    both companies first introduced their collaboration ultimate summer.

    The road map contains three new joint options “to dramatically enhance business communications with the aid of breaking down the limitations between voice, e mail, fast messaging, multimedia conferencing and different forms of communique,” in response to a press release via the two corporations.

    additionally covered within the announcement are 11 new implementation capabilities from Nortel and the outlet of more than 20 joint demonstration facilities where shoppers can journey the technology, the statement persisted.

    additionally, the two agencies said they've signed agreements with dozens of customers, and have developed a “pipeline of lots of of prospects who need to understand the advantages of unified communications.”

    From Microsoft's point of view, it is all a part of the business's lengthy-term play to merge every kind of communications and messaging into a single framework. A yr ago, the company introduced that it become merging its alternate Server neighborhood with its true-Time Collaboration (RTC) group, and that it had begun to consider of both technologies comprising a "platform."

    Avaya lays out Nortel migration street map | killexams.com Real Questions and Pass4sure dumps

    Avaya day after today will exhibit a street map that indicates how its valued clientele – in particular its newly minted Nortel valued clientele -- can flow to unified communications applied sciences with out ripping out current gear.

    Avaya tomorrow will reveal a highway map that indicates how its valued clientele – in specific its newly minted Nortel consumers -- can movement to unified communications applied sciences devoid of ripping out present apparatus.

    the upward thrust and fall of Nortel

    The plan specifically addresses how the business will dispose of overlap between its own and Nortel's product lines, once in a while favoring Avaya expertise, occasionally Nortel's, in the areas of unified communications, contact centers, small and midsize corporations as well as network infrastructure. on the same time the plan permits cost mark downs by means of SIP trunking for you to let consumers send voice and information over one pipe in place of diverse lines and other reduced costs with the aid of centralizing administration of corporate phone methods, Avaya says.

    The internet effect, says Alan Baratz, senior vice chairman and president for world verbal exchange options at Avaya, is accelerated capabilities, decreased charges and less disruptive alternate.

    Promising to achieve a major a part of this inside the year is an aggressive goal that may also galvanize Nortel shoppers looking for a pretty path to unified communications, says Zeus Kerravala, an analyst with the american group.

    Chart showing what products will come out of Avaya Nortel

    supplying on time is crucial as a result of former Nortel purchasers that want to aggressively pursue UC won't wish to wait and wait, he says. Avaya CEO Kevin Kennedy's time at Cisco might also support as a result of that rival's adventure in buying other businesses and integrating them smoothly, he says.

    "each Nortel client is going to have a aggressive seller trying to create a course to their own unified communications solution," he says. Fumbling won't be deadly, Kerravala says, however may mean a lack of the extraordinary 25% marketshare he says Avaya has accrued in telephony.

    As for the specifics of the street map, adding an essential SIP layer into the communications hierarchy may be completed by means of Avaya aura, the company's SIP-based mostly verbal exchange utility platform that may be sandwiched between communications infrastructure - equivalent to PBXs - and features - equivalent to voice, video, messaging, conferencing and mobility.

    With air of secrecy in place, legacy Avaya and Nortel PBXs will interoperate with SIP-primarily based VoIP apparatus. So Nortel conversation Server 1000 IP PBX with air of mystery layered on right of it could interface with SIP-based mostly telephones plugged into the charisma aspect of the community. all of the telephones would have CS a thousand features and the equal button sequencing with the intention to navigate those features, Baratz says. also, legacy Nortel phones could be plugged into the charisma side of the community.

    This circulation will reduce cost of adopting unified communications because it reduces the need for changing PBXs and phones as neatly as the charge of retraining end clients in how new telephones work, he says.

    The plan requires application integration and it may not occur overnight, Baratz says, but it will be achieved via the conclusion of this 12 months, probably in November, Baratz says. Nortel's business Communications gadget supervisor can be included into charisma, as will Nortel's Agile Communications atmosphere (ACE), which permits infusing functions with communications capabilities.

    The changes might be allotted as utility enhancements to present air of secrecy valued clientele.

    This approach isn't excellent, Kerravala says, because charisma turned into designed to include an SIP-based mostly gear, no be counted who the dealer. Integration with Nortel equipment should still be more convenient because Avaya owns each sets of property so could make their SIP implementations suitable. necessities-compliant implementations of SIP can range ample that they don't interoperate, he notes.

    in the area of contact centers, Avaya will improve Nortel Contact center application after which integrate it into its latest line. Over the subsequent six to nine months, further revisions of Nortel's Contact middle will prepare it to turn into the Avaya offering for midsize groups in preference to Contact center categorical.

    After that, the contact center application from Nortel might be evolved to incorporate architectural aspects from both Nortel and Avaya traces, then additional developed to scale to enterprise proportions. These two revisions will take six to nine months each and every. At that element the utility will turn into an upgrade to change Avaya's excessive-end Contact center Elite.

    Baratz says that even earlier than the acquisition of Nortel, Avaya recounted that Nortel's midsize contact core changed into superior. "It changed into very close to the most efficient product we desired," he says.

    Avaya plans to slowly cut back the variety of telephony alternate options obtainable for small and midsize agencies. It plans to convey legacy Avaya associate and fundamental 5 key techniques in addition to Nortel Norstar techniques beneath the umbrella of its IP office equipment.

    IP workplace may be developed to support Norstar techniques and Nortel company Communications supervisor hybrid PBXs, and a few years down the line will exchange them. but meanwhile, Norstar and BCM will remain attainable. "Nothing abrupt goes to occur here," Baratz says.

    Nortel's application Communications device SIP equipment will join the portfolio as is. There is no analogous Avaya product.

    Nortel brought alongside a portfolio of switches, network safety and wireless gear for which Avaya has no competing device. Avaya plans to promote these products and increase them to interoperate more carefully with its unified communications infrastructure, Baratz says.

    as an instance, the instant apparatus and switches will also be tweaked to supply greater complete information about the presence of cellular laborers. presently they display no matter if an individual is attainable by means of voice. With more advantageous integration they might say that the particular person is available on a mobile equipment and the place it is discovered, he says.

    however Kerravala says that Avaya needs to enhance its gear to be aggressive with other infrastructure companies characteristic for characteristic, not just to have switches and routers that increase communications.

    Xen Project Hypervisor 4.12 Offers Smaller Code Size and Improved Security | killexams.com real questions and Pass4sure dumps

    (MENAFN - PR Newswire)

    SAN FRANCISCO, April 2, 2019 /PRNewswire/ -- The Xen Project , an open source hypervisor hosted at the Linux Foundation , today announced the release of Xen Project Hypervisor 4.12. This latest release adds impressive feature improvements around security and code size, x86 architectural renewal and additional updates making the technology ideal for embedded and automotive industries.

    The leaner architecture in Xen 4.12 reduces the lines of code and in turn, reducing the potential for security vulnerabilities while making Xen an attractive option for use in mixed-criticality systems. Additionally, improving de-privileged QEMU, through defense-in-depth techniques, as well as improving VMI, reduces exposure to unknown security threats. This version of Xen will be more configurable, significantly reducing integration costs for business and organizations which customize Xen heavily. Additionally, Xen 4.12 continues to build upon previous versions regarding cleaner architecture, improved user experience, and future proofing.

    "Xen Project Hypervisor 4.12 is a clear example of the project delivering on its promise for revamped architecture, a major step forward to unlock market segments such as security products as well as embedded and automotive," said Lars Kurth, chairperson of the Xen Project Advisory Board. "As we continue to serve the hosting and cloud markets, we will also focus on streamlining the certification process for Xen while helping the security embedded automotive vendors that are invested in Xen continue to build attractive products on top of the hypervisor."

    Security & Code Size

    The Xen 4.12 release builds upon the security features of previous releases, continuing Xen's legacy of being the safest and most stable hypervisor for security-focused environments.

  • HVM/PVH and PV only Hypervisor: The new Xen Project 4.12 release separates the HVM/PVH and PV code paths in Xen and provides KCONFIG options to build a PV only or HVM/PVH only hypervisor. This enables Xen based security products such as Qubes OS, Star Lab Crucible, & OpenXT to more easily build products with vastly reduced memory footprint and attack surface. In addition, the release enables cloud and hosting providers which do not offer support for PV guests to deploy HVM/PVH only hypervisors which in turn, increases security.
  • QEMU Deprivilege (DM_RESTRICT): Xen's previous three releases laid the groundwork for the QEMU Deprivilege, limiting the impact of security vulnerabilities that originate QEMU. In Xen 4.12, this feature has been vastly improved. The majority of restrictions and features have been implemented, improving security and readiness for wide-scale testing. Support for VM migration has also been added and defense-in-depth techniques using chroot, RLIMITs, and Linux namespaces which are used to protect against privilege escalations from QEMU to Xen and VM's.
  • Argo - Hypervisor-Mediated data eXchange: Argo is a new inter-domain communication mechanism that is designed for security, safety and mixed-criticality systems with isolation properties that go beyond those of existing inter-domain communication mechanisms. Argo is designed to be robust and simple to use correctly, securely and safely. In addition, Argo meets requirements for performance isolation between domains, to prevent negative performance impact from malicious or disruptive activity of other domains, or even other VCPUs of the same domain. It follows Multiple Independent Levels of Security/Safety (MILS) architecture foundational principles. Argo provides Xen hypervisor primitives to transmit data between VMs, by performing data copies into receive memory rings registered by domains. It does not require memory sharing between VMs and does not use grant tables or Xenstore.
  • Improvements to Virtual Machine Introspection: The VMI subsystem which allows detection of 0-day vulnerabilities has seen many functional and performance improvements. Altp2m (see https://xenproject.org/tag/alt2pm/ ) and Intel #VE/VMFUNC support within the subsystem have been tuned and hardened. These two technologies reduce the performance overhead of Virtual Machine Introspection by 5% to 20% depending on workload.
  • x86 Architectural RenewalThe new Xen 4.12 features renew how x86 architecture support is implemented in Xen, a multi-year effort that is nearing completion.

  • Credit 2 Scheduler: The Credit2 scheduler is now the Xen Project default scheduler. This Credit2 scheduler represents several years worth of effort to create the next-generation scheduler for Xen. It is designed specifically for performance of latency-sensitive workloads, as well as scalability and predictability.
  • PVH Support: Grub2 boot support has been added to Xen and Grub2. These additions enable users to boot any PVH guest kernel via the grub menu. The updates to PHV also improves its stability.
  • PVH Dom0: PVH Dom0 support has now been upgraded from experimental to tech preview. This upgrade, exclusive to Intel Hardware, resolves various bugs and features several improvements such as the new dom0-iommu=map-reserved option which can be used to work around broken firmware when using a PVH Dom0. Support for migrating domUs from a PVH dom0 has also been included.
  • Embedded/AutomotiveThe Project is working to make Xen more easily safety certifiable targeting embedded and automotive use-cases. These new upgrades will increase the viability of Xen for use in mixed-criticality systems.

  • Dom0less VMs for statically partitioned systems: The new Xen 4.12 upgrade makes it possible to create and boot Arm VMs from Device Tree immediately after starting Xen. In traditional Xen environments, VMs can only be started after Dom0 kernel, user space and the toolstack are up and running. The upgrade decreases boot time by more than 90%. Dom0less VMs extend the usage of Xen to statically partitioned mixed-criticality systems. Xen is planning on extending the concept of Dom0less in subsequent releases to allow building Xen Systems entirely without a Dom0. This, in turn, will reduce the cost of safety certification significantly.
  • Tiny Arm Configurations: The Xen 4.12 upgrade allows users to build a tiny Arm configuration with less than 50 KSLOC, which in turn reduces the cost of safety certification for Xen based systems. This new functionality allows building Xen variants for specific hardware such as Renesas RCar 3 and Xilinx Ultrascale+ MPSoC with a minimal set of drivers and features that are needed for mixed-criticality systems.
  • Additional Technical FeaturesThe new Xen 4.12 upgrade also includes improved IOMMU mapping code, which is designed to significantly improve the startup times of AMD EPYC based systems.

    The upgrade also features Automatic Dom0 Sizing which allows the setting of Dom0 memory size as a percentage of host memory (e.g. 10%) or with an offset (e.g. 1G+10%).

    Comments from Xen Project Users and Contributors:

    Apertus Solutions"With today's introduction of the hypervisor-mediated exchange protocol Argo, Non-bypassable and Always-invoked (NEAT) properties are now possible with the Xen hypervisor," said Daniel P. Smith, Chief Technologist at Apertus Solutions. "Early separation kernel concepts were defined in the 1980's by John Rushby's seminal work, extended by Jim Alves-Foss for virtual systems, and distilled into NEAT properties for Multiple Independent Levels of Separation (MILS) systems. Apertus Solutions looks forward to future Xen Security Modules (XSM) type assertion capabilities that only a hypervisor-mediated exchange protocol like Argo can deliver on a per-message basis, on the trusted computing foundations of DRTM, TrenchBoot, disaggregated Xen and OpenXT."

    Xen Project Hypervisor 4.12 Offers Smaller Code Size and Improved Security

    Stealth and Lasers: How the Navy's New Zumwalt-Class Destroyer Will Sink Your 'Battleship' | killexams.com real questions and Pass4sure dumps

    The larger the amount of exportable, ruggedized mobile power technology, the stronger the laser. Ship-based laser weapons, it is widely discussed, are now operational. The challenge moving forward is to succeed in increasing their strength and range while accelerating its integration with radar, sensors and fire control technologies.

    As the Navy commissions its second Zumwalt-class stealthy new destroyer, the service is expanding the strategic scope for the attack vessels and engineering the ships for new weapons, improved sensors and advanced applications of Artificial Intelligence and cloud technologies.

    (This first appeared last month.)

    Beneath the highly visible shadow of its first-in-class stealthy USS Zumwalt destroyer, the Navy has been quietly making rapid progress with its second Zumwalt-class destroyer – the now commissioned USS Michael Monsoor. The Monsoor was commissioned last month.

    Much like the lead Zumwalt-class ship, the 2nd is envisioned as a stealthy, multi-mission land and blue-water attack platform armed with long-range precision fires, a wide range of offensive and defensive missiles, faster computer processing speed and an electric drive Integrated Propulsion System with 78-megawatts of on-board electrical power.

    “DDG 1001 employs an Integrated Power System (IPS), distributing 1000 volts of direct current across the ship. The IPS' architectural capabilities include the ability to allocate all 78 megawatts of installed power to propulsion, ship's service, and combat system loads from the same gas turbine prime movers based on operational requirements,” a statement from Naval Sea Systems Command said.

    The ship, called DDG 1001, has now been commissioned following extensive tests, trials and demonstrations of the ship's HM&E systems (Hull, Mechanical & Electrical) including the boat handling, anchor and mooring systems as well as major demonstrations of the damage control, ballasting, navigation and communications systems, a statement from Naval Sea Systems Command said.

    The HM&E delivery follows Navy reports of successful acceptance trials for DDG 1001 during which the ship tested power propulsion systems and high-speed turns while also assessing the HM&E engineering systems, according to a statement from General Dynamics Bath Iron Works.

    Using the same technical baseline, ship specs and weapons system as the first Zumwalt, the Monsoor is engineered with a computer system specifically designed to accommodate software upgrades as new technologies emerge, Raytheon and Navy developers describe.

    The ship computer, called Total Ship Computing Environment, integrates many of the ship’s systems such as its radar, weapons and propulsion apparatus. Software upgrades impacting radar, fire control and some weapons areas represent some potential margins of difference making the ships more advanced. Raytheon is the primary ship integrator of the on-board computers and other Zumwalt-class technologies.

    “We are continually looking to further optimize the total ship computing environment through technology refresh. This could eventually include AI and/or cloud-based solutions,” Wade Knudson, Raytheon’s Senior Director of Total Ship Integrated Systems, told Warrior Maven.

    AI or cloud integration, should that happen in the near future, brings several new dimensions to maritime attack. One initial advantage, simply, is that increased virtualization enabled by cloud migration can greatly reduce the hardware footprint. Fewer “boxes” or servers will be required on board as a greater elements of the technical infrastructure become multi-function. Fewer numbers of sensors and data storage technologies allow for better integration and free up what’s called “size, weight and power” opportunities on board the ship.

    Data access is another defining element of cloud migration, meaning sensors, weapons systems and things like navigational data can be accessed in a faster, more consolidated fashion. When greater automation or AI are added to the equation, sensor, targeting and weapons information can even be organized autonomously for human decision makers to consider.

    AI integration could automate sensor and weapon integration - by comparing new information against vast volumes of data to analyze and organize combat-relevant data; this will give commanders a much improved sensor-to-shooter time with which to destroy fast-approaching targets.

    Meanwhile, the third-in-class Zumwalt, the future USS Lyndon B. Johnson, has also been under construction and is nearing completion. The 3rd Zumwalt’s deck house, which unlike the first two ships built with composites, is made out of steel.

    The three-ship Zumwalt fleet is likely to be in great demand in coming years as new threats emerge which present a need for its unique technologies. Given its stealthy configuration, it seems plausible that a Zumwalt class ship could lead an assault or help launch a broader attack by virtue of an ability to strike while avoiding detection.

    Also, in a manner quite similar to the current fleet of DDG 51 destroyers, a Zumwalt will almost certainly help protect a carrier strike group. Drawing upon its stealthy configuration, a Zumwalt destroyer might be well positioned to test or penetrate blue-water enemy defenses without necessarily surrendering the location of a carrier group.

    Secretary of the Navy Richard V. Spencer recently mentioned the larger role of the Zumwalt-class, saying "This ship will provide independent forward presence and deterrence for decades to come,” according to a written statement from Naval Sea Systems Command.

    If radar, aerial ISR or on-board MH-60Rs and Fire Scout drone assets detect long range threats or areas of incoming enemy fire, the Zumwalt could very well be called upon as a launching point for a counterattack.

    Navy officials explain that, compared to previous destroyers, the Zumwalt-class fields a larger flight deck and has capacity for two MH-60R and multiple drones.

    With its long-range precision gunfire technology, a Zumwalt could perhaps be successful in attacking more fortified enemy land targets without itself being as susceptible to land-based sensors and anti-ship missiles.

    Navy developers also say that the USS Michael Monsoor's Vertical Launch System features cells physically larger than similar cells on today's ships, allowing this class to fire larger and more advanced land and anti-ship missiles in the future.

    Furthermore, given its low radar signature, it might not seem like too much of a mission stretch to envision a Zumwalt-class destroyer as an element of an amphibious assault. Advanced on-board sensors could connect with drones and other ISR assets to help orient an approaching Amphibious Ready Group as to the best methods or locations of attack.

    The 610 foot, wave-piercing tumblehome ship design provides a wide array of advancements. The shape of the superstructure and the arrangement of its antennas significantly reduce radar cross-section, making the ship less visible to enemy radars, a Navy statement writes.

    A Zumwalt’s shallow draft, littoral mission abilities and long-range precision fires could, in tandem with air power, help soften land targets in preparation for an amphibious landing. In a manner not entirely unlike an LCS, a Zumwalt could access shallow water ports and other coastal areas currently inaccessible to deeper draft vessels; this changes the combat calculus in that brings substantially enhanced surface firepower to littoral operations.

    At the same time, it is undoubtedly relevant to point out that, at least for the moment, will only be three Zumwalt class destroyers – a circumstance likely to limit a more ubiquitous global reach. As a result, it takes little imagination to observe how the Zumwalt-class is likely to function as an inspiration or model for other new ships and innovations, to emerge in the future, which may emulate or build upon some of its technologies.

    The question of rail guns and lasers weapons, without surprise, is something which tends to generate much attention in the minds of innovators, threat assessment analysts and future planners; this is a key reason why many point to the Zumwalt’s Integrated Power System as an impactful mobile power source which, as it continues to evolve, provides the technical foundation for the integration of laser weapons.

    The larger the amount of exportable, ruggedized mobile power technology, the stronger the laser. Ship-based laser weapons, it is widely discussed, are now operational. The challenge moving forward is to succeed in increasing their strength and range while accelerating its integration with radar, sensors and fire control technologies.

    SSA goes big on VOIP | killexams.com real questions and Pass4sure dumps

    CASE STUDY

    SSA goes big on VOIP

    Agency’s program is one of the world’s largest voice-over-IP implementations

  • By William Jackson
  • May 27, 2009
  • The Social Security Administration is about a third of the way into a program to replace phone systems at 1,526 field offices nationwide with a single, centrally managed voice-over-IP solution that runs on the agency's data network.

    By late February, the VOIP system had handled more than 1.6 million calls. SSA officials expect to add as many as 16 offices a week to the new system during the next two years, said Roderick Hairston, deputy associate commissioner of SSA's Office of Telecommunications and Systems Operations. When completed, the system will be one of the largest VOIP deployments in the world.

    "For SSA to go with VOIP to this extent, they had to have a lot of faith in it," said Benjamin Moses, vice president of solutions at Nortel Government Solutions, the project's lead contractor.

    The agency needed technology that could help increase productivity during the labor crunch officials expect in the coming years. "They are losing employees, and they are getting ready to deal with the baby boom explosion of retirees," Moses said.

    SSA's network of field offices has 63,000 employees and a budget of about $10 billion a year. The agency paid $650 billion in Social Security benefits to 55 million people in 2008, and for years, it has been preparing for a wave of baby boomer retirements. SSA will be hit twice because many of its employees will reach retirement age at the same time the agency's workload spikes.

    That process has already started. SSA's field office staff decreased by 4.4 percent from 2005 to 2008, according to a recent study by the Government Accountability Office. Visits to SSA offices increased from 42 million in 2006 to 44.4 million in 2008. Forty-four percent of the agency's staff is expected to retire by 2016, while the agency expects to be processing 1 million additional claims a year from retiring boomers by 2017.

    Meanwhile, the agency's telephone infrastructure was aging. It had never been a single system but rather a collection of separate systems with different carriers at each office.

    "Our system was more than 12 years old," Hairston said. "Some of it was past its end of life, and other parts were approaching it. We have been running out of parts," and the tasks of adding, dropping or moving lines were lengthy and labor-intensive. "We really had to do something to replace them. This was a perfect opportunity to look at what kind of system we needed."

    What officials needed was a single system that could be centrally managed and offer a common look and feel for employees and customers. They wanted to be able to balance traffic among offices and re-route calls in case of an outage, and they wanted to be able to consolidate trunk lines to save money. The result of that assessment was the 10-year, $300 million Telephone Systems Replacement Project (TSRP).

    Because it was a wholesale replacement rather than an upgrade, "it was pretty much a no-brainer" to go with VOIP, Hairston said. "We made the decision in 2003 to do it, but only after we did a pilot. It was a fairly new technology when we made the decision."

    The pilot project was conducted from 2004 to 2006 at 43 offices, with separate systems operated by AT&T and Nortel as primary vendors. The results were satisfactory, and Nortel Government Solutions was awarded the TSRP contract in 2007. Implementation began in March 2008.

    The system uses Nortel's Contact Center Manager Server, Communication Server 1000 for switching, Media Processing Server 500 for interactive voice response, Unified Messaging 2000 for voice mail and IP Phone 1100 Series handsets. Other members of the contractor team include General Dynamics, Black Box Network Services, Shared Technologies, York Telecom, High Wire Networks, NetIQ, Netcom Technologies, AttivaSoft and Pal-Tech.

    There are separate parts to an IP phone system, Moses said. The IP telephony functions — the core switching and applications such as interactive voice response and call records — reside on the network and are independent of the means used to transport calls.

    "VOIP is really transport," he said. "All we're doing is pointing to a [Session Initiation Protocol] trunk rather than to a [public switched telephone network] trunk. The applications are available either way." But VOIP allows trunk consolidation and better bandwidth use for improved pricing. "VOIP is a cost issue — it's not about application availability."

    Combining the applications with the transport is the trickiest part of the implementation.

    "If it was just providing a dial tone, it wouldn't be much more than putting a few servers on the network," Moses said. "This customer has an extremely interesting application environment."

    One of the most unusual features of SSA's systems is the ability to partition call and performance data for each level of management. Managers log on through a Web front end, using SSA's authentication system, for access to the data that they are authorized to see. An office manager has access to data and security controls only for that office. District, regional and headquarters managers have access to progressively broader swaths of data.

    Applications and dial tone are provided from four redundant service delivery points at Richmond, Calif.; Kansas City, Mo.; Durham, N.C.;and the SSA computer center in Baltimore. The service delivery points provide automatic failover in case of an outage.

    "We have experienced an outage," Hairston said. "It works very well."

    Each office has a separate gateway to the public switched telephone network for additional failover. In case of a local-area or wide-area network outage, the phone can automatically re-register to the PSTN. Emergency 911 service is directed through the PSTN gateway on a local trunk, so that the public safety answering point receives accurate information about the number and address from which the call is being made.

    The handsets also do their part to ensure quality of service. Each acts as a voice quality agent, and when quality moves outside acceptable parameters, the system automatically alerts the service delivery point. Calls can be re-routed, problems identified and solutions launched without interrupting the call.

    Ultimately, the quality of voice service depends on the quality of the network transporting it. Nortel works with SSA's Division of Network Engineering to analyze network health and troubleshoot problems before an office implements VOIP.

    "In most cases, they are in pretty good shape," Moses said. "Our solution is somewhat tolerant" of network conditions.

    "We learned from the pilot how to tune the network and get voice traffic where it needed to be," Hairston said.

    SSA was fortunate that it had done a major network upgrade shortly before TSRP, during which it implemented Multiprotocol Label Switching. MPLS supports multiple services and simplifies traffic management for applications such as voice and video that are sensitive to latency. A few years ago, it was an expensive, leading-edge technology used primarily by large service providers to provision multiple services, but affordable high-performance MPLS routers now are available in a variety of sizes, making the technology practical for other organizations.

    SSA still has a lot of work to do to transition field offices to VOIP, said Andre Pinto-Lobo, program manager at Nortel Government Solutions. "We are coming to the end of Year One," he said. The rate of implementation will increase during the second and third years and then slow again as the implementation concludes.

    But "we're seeing the advantages already," Hairston said. System management has been simplified, there is better redundancy, and calls can be better routed to the proper person or automated service, which should please both employees and retiring baby boomers.
