Debunking the myths of the protection of entry control programs

It’s no longer fabulous that people are fearful in regards to the protection of more moderen applied sciences, lots of which can be a part of the cyber web of things (IoT). while they present improved effectivity and connectivity, some people nevertheless hesitate. after all, there seems to be a relentless circulation of information studies about multinational enterprises being breached or hackers taking handle of sensible home gadgets. each of those eventualities can feel personal. nobody likes the thought of their statistics falling into crook palms. And we in particular don’t just like the thought that a person can, even virtually, come into our deepest spaces. The fact, although, is that, in the event you opt for the appropriate expertise and undertake the relevant procedures, IoT instruments are tremendously comfy. That said, one of the vital spaces where we see persevered confusion is round access control methods (ACS) that are deployed over networks, especially in relation to mobile entry, smartcards, and digital locks. These applied sciences are sometimes perceived as being less secure and hence extra at risk of assaults than older ACS systems or gadgets. in the activity of clearing up any confusion, it's vital to give respectable, legitimate guidance. With this in mind, there are some myths out there about the security of ACS that need to be debunked. The fact that these contraptions speak with an ACS by way of Bluetooth or close box verbal exchange (NFC) results in one of the main myths we come across myth #1: cellular credentials are not secure the first myth we ought to analyze exists around cellular credentials. cellular credentials allow cardholders to access secured doors and areas with their cellular contraptions. The undeniable fact that these instruments communicate with an ACS by means of Bluetooth or close container communication (NFC) results in some of the leading myths we encounter about the security of credentialed suggestions. there's a persistent perception that Bluetooth isn't secure. In certain, people seem to be anxious that the use of cell credentials makes your enterprise extra susceptible to skimming attacks. while specializing in the medium of verbal exchange is an important consideration when an supplier deploys a cellular credentialing equipment, the concerns about Bluetooth omit the mark. Bluetooth and NFC are conveniently channels over which tips is transmitted. Believing that Bluetooth isn't secure would be the identical as suggesting that the cyber web is not cozy. In each cases, the safety of your conversation depends on the expertise, protocols, and safeguards we all have in region. So, as a substitute of wondering about Bluetooth or NFC, users should still be focused on the protection of the devices themselves. before deploying cellular credentials, ask your dealer (1) how the credential is generated, saved, and secured on the device, (2) how the device communicates with the reader, and (3) how the reader securely accesses the credential tips. if you installation smartcard expertise as part of your ACS, make sure to opt for the newest technology, akin to MiFARE DesFIRE EV1 or EV2 and HID iCLASS SEOS fantasy #2: All smartcards are equally comfy The query “how cozy are my smartcards?” is a significant one. And the reply can rely on the era of the playing cards themselves. for instance, whereas older smartcards like MiFARE classic and HID iCLASS classic present improved encryption than proxy playing cards and magstripe credentials, they have got been compromised. the use of these older technologies could make your employer vulnerable. subsequently, for those who deploy smartcard know-how as a part of your ACS, you'll want to select the newest technology, similar to MiFARE DesFIRE EV1 or EV2 and HID iCLASS SEOS. during this manner, you may be retaining your equipment in addition to your structures or amenities. Some natural readers and controllers can also pose a major possibility to your supplier in the event that they use the Wiegand protocol, which offers no safety. while you could improve to a more relaxed protocol like OSDP edition 2, digital locks are a extremely at ease alternative value considering the fact that. it's also essential to remember not all smartcard readers are compatible with all smartcard varieties. after they don't seem to be suitable, the constructed-in protection designed to preserve your gadget secure will now not in shape up and you will well-nigh forego safety as your smartcard-reader will now not study the credentials in any respect. as a substitute, it's going to with no trouble read the non-comfortable portion—the cardboard Serial number (CSN) —of the smartcard this is obtainable to every person. whereas some manufacturers suggest that this is an potential as a result of their readers can work with any smartcard, the truth is that they aren't studying from the secure a part of the card, which can put your gadget and premises in danger. using digital locks can support give protection to amenities and networks through various safety protocols, together with encryption and authentication fable #three: electronic locks are more inclined this present day, there are nonetheless many who agree with that digital locks, specifically wireless locks, are greater susceptible to cybercriminal endeavor as in comparison to ordinary readers and controllers. The concern here is that digital locks can allow cybercriminals to both access your community to get facts and intercept commands from the gateway or nodes over the air that might permit them entry to your buildings or amenities. The reality is that the usage of electronic locks can aid protect amenities and networks through a considerable number of protection protocols, including encryption and authentication. additionally, as a result of many of these locks stay operational inspite of community status, they provide actual-time door monitoring. This ability that many electronic locks now not simplest steer clear of unauthorised access however additionally keep operators counseled about their repute at all times, notwithstanding a network goes down. out of date expertise and historical analogue methods are extra susceptible to attacks When it involves deploying electronic locks, it is essential to bear in mind that, like several machine on your community, they should have developed-in security aspects in order to can help you retain your information, individuals, and facilities safe. Be prepared to free up future benefits finally, the counsel for your IP-primarily based ACS is at no greater chance than another assistance being transmitted over the community. We simply ought to be wise about how we connect, transmit, and store our statistics. in the conclusion, holding the repute quo and refusing to circulate faraway from historical know-how isn't a doable choice. outdated expertise and ancient analogue systems are extra vulnerable to assaults. The purpose it's so vital to debunk myths around ACS and, at the identical time, get individuals thinking about community protection in the right method is that network-based techniques can offer an ever-increasing variety of merits. after we deploy new technology the use of trade most suitable practices and purchase instruments from trusted carriers, we put ourselves and our networks in the absolute best position to take full capabilities of all that our more and more connected world has to present.

in opposition t all odds: How Ciena and its Nortel engineers won optical | killexams.com Real Questions and Pass4sure dumps

Dino DiPerna, VP of Transport and Switching R&D at Ciena, led the group that saved Nortel's optical group. Julie Oliver / Ottawa Citizen

on the time, it seemed the area become ending.

Lehman Brothers’ investment financial institution had filed for bankruptcy on Sept. 15, 2008, triggering a world fiscal disaster. The next night, Dino DiPerna – the top of R&D for Nortel Networks’ optical networks group – become trying to calm down in his Boston resort room when he got a name from his boss, Philippe Morin. one other shock. Morin advised his colleague their group could be put up on the market the following morning.

DiPerna — a protracted-serving veteran of this unforgiving industry – knew there would be fallout, lots of it. certainly, Nortel’s competitors lost no time spreading vicious gossip in regards to the weaknesses inside. They claimed Nortel’s optical enterprise had been starved of elements, its engineering talent drained away. These and different rumours accelerated in January 2009 when Nortel sought the insurance policy of bankruptcy court.

DiPerna knew the gossip, most of it, wasn’t real. but to persuade Nortel’s valued clientele, he and his colleagues logged a whole bunch of heaps of miles to reassure them in grownup. a further equally vital mission became to prevent competitors from poaching Nortel’s most appropriate engineers.

“I’m proud to say they received very few of our people in the end,” DiPerna says. “we've a lifestyle of sticking it out via tough times, a belief in ourselves, in our capability to innovate.”

The stretch of gigantic uncertainty produced an sudden advantage. 

“It was us against each person,” DiPerna adds, “and it made us more advantageous.”

greater to the aspect, DiPerna’s optical items group – called Metro Ethernet Networks – grew to be a tremendously sought property. 

On March 19, 2010 – greater than a year into Nortel’s gut-wrenching bankruptcy – Maryland-based Ciena shelled out $774 million US to purchase the Metro Ethernet Networks unit.

The minute it did, the business gossip stopped and a gruelling multi-yr integration of the two groups started.


Now, finally, the payoff is apparent.

For the previous 12 months, Kanata commuters were handled to the rare sight of a significant new excessive-tech campus beneath construction along Terry Fox power simply west of March highway.

Ciena employees are moving in waves from Nortel’s longtime base at Carling Avenue and Moodie pressure in the west conclusion of Ottawa. the primary community is filling an adjoining one hundred seventy,600 square-foot facility at 5050 Innovation Dr. in the past constructed via BlackBerry but not ever occupied. beginning in January, the leisure of the Ciena people will circulation into two new towers on Terry Fox pressure — comprising an additional 254,300 square toes of leased space. 

by the point the brand new Ciena challenge is achieved, undoubtedly in September 2017, the cluster will apartment about 1,600 personnel — confirming the enterprise’s status as the location’s 2nd-greatest technology employer after Nokia. 

extra essential than the dimension of the Ciena campus is its role: a majority of the business’s global R&D is completed right here. And when it involves optical technology — the high-velocity core of nowadays’s web — Ciena is the No. 2 company on the planet in the back of China’s Huawei, and No. 1 in North the usa.

“It become the deal of a lifetime,” says James Frodsham, Ciena’s chief method officer — and the man in can charge of buying different businesses. 

however took much more than one harmful bet to make this combo work. It required a collection of them – with the aid of Ciena and Nortel alike. this is the story of how they did it.


in case you are looking to be aware why Ciena survived and Nortel didn't, the finest beginning aspect is February 2001 – the month the telecom industry’s foundations cracked. On Feb. 9, Ciena achieved the sale of convertible debt and eleven million shares for a net payoff of $1.6 billion US. The Maryland enterprise bought in exactly beneath the wire. Six days later, Nortel printed its revenues would gradual — the first of many such announcements that yr.

by using the conclusion of 2001, Nortel would listing annual income of just $17 billion in comparison to its common forecast of $forty billion. with out a end in sight to the income slide or the multi-billion dollar annual losses, Nortel now not had the option of shoring up its stability sheet by using issuing shares to traders. no person became fascinated.   

The initial move of DND employees to the former Nortel Campus on Moodie Dr at Carling Ave. has been delated until late 2015.

Former Nortel Campus on Moodie Dr. Chris Mikula / Ottawa Citizen

The company’s failure to sell shares when it became flying excessive would go away it fatally inclined all over the 2008-09 international economic crisis. 

It become a a lot distinct circumstance at money-prosperous Ciena, which in 2001 had the flexibleness to be artistic. The business reached that place no longer because it become extraordinarily prescient — infrequently anybody within the industry noticed what became coming that 12 months. youngsters, Ciena simplest had around six years of operations beneath its belt on the time. It turned into very lots a startup, and very aware of the should elevate cash when situations authorised. And so it did.

From 2001 to 2004 — the telecom trade’s “nuclear iciness” — Ciena shelled out greater than $2 billion to purchase 5 networking expertise experts, together with Akara and Catena Networks from Ottawa. through these purchases, Ciena considerably broadened its product strains.

“if you happen to get these periods of incredible uncertainty, possibility and dislocation, it’s an opportunity to change the video game,” Ciena CEO Gary Smith says. “We positioned some very big bets but i'd say they were calculated.”

At Nortel’s Metro Ethernet Networks unit, equally massive risks had been being meditated. but these were brought about by using desperation in place of opportunity. 

Nortel consumers reminiscent of Qwest Communications and Verizon radically pared back orders for communications apparatus starting in 2001. That’s when DiPerna and his engineering team knew that they had a big problem — rather other than the loss of revenues.

The problem become cost: their items were expensive to supply, anything that hadn’t mattered all over the telecom increase. but now it did.

Nortel had received the late Nineteen Nineties world race to supply an optical transmission expertise capable of pushing records through the internet at speeds of 10 billion bits per second (10 gigabits). Bumping up the pace in subsequent-technology programs (forty gigabits) down a similar direction of expertise would require the use of better-nice optical fibre and expensive pieces of equipment to regenerate signals.

no longer best have been purchasers now unwilling to pay for these technical enhancements, they nevertheless wanted larger speeds to be able to accommodate the starting to be use of online video and other digital site visitors.

DiPerna and his team spent months brainstorming along side consultants in instant expertise and electro-optical devices. They reached a fateful conclusion. as opposed to force valued clientele to add costly new optical methods, they might create technology for extensively increasing the ability of existing optical fibre — anything that demanded distinctive technical breakthroughs. The team wasn’t sure it may be performed.

The engineers shrank analog-to-digital converters and applied digital sign processing in unique approaches. They used these constructing blocks to design a brand new forty-gigabit chip, which they unveiled in 2005 and began testing it here year. This, in flip, fashioned the heart of the 40-gigabit optical device — which Nortel introduced in March 2008. That changed into just six months before DiPerna learned Nortel would put his Metro Ethernet Networks unit up on the market.

but it became sufficient. the new forty-gigabit gadget — dubbed digital coherent optical — was becoming the business’s new typical for sending information alongside the cyber web’s backbone. “We guess every thing on coherent,” says DiPerna, “That’s what saved us going through the 2000s.” 

ownership would soon pass from Nortel. but the decent information changed into digital coherent technology gave the Metro Ethernet Networks unit some precise price.

Ciena became some of the first knowledge buyers to express activity in purchasing it.

“We’d been trying to find a long time at Metro Ethernet, principally a expertise referred to as coherent,” Ciena’s Gary Smith says. “These guys have been means forward of us.”

Ciena CEO, Gary Smith, offers a presentation on the convergence of Nortel and Ciena to former Nortel employees from Ottawa and Montreal in 2010. THE OTTAWA CITIZEN

James Frodsham — a Ciena executive in view that 2005 and a former Nortel manager — led the examination of Metro Ethernet Networks. He changed into normal with Nortel’s optical expertise crew and knew what they have been capable of doing. What neither he nor his boss Smith may make certain about turned into the first-class of Nortel’s product line. When Nortel become losing buckets of money during the telecom crash, simply how lots funds had been withheld from R&D? And which tasks had been damage the most?

here's what they found: “Philippe and Dino needed to a great extent blanketed the assets and the team from frankly all of the trauma and mismanagement at the top in the broader Nortel,” Smith says. “that they had managed to shoestring investments collectively and stored the skill. It changed into a large surprise.”

DiPerna’s massive concern turned into that Metro Ethernet Networks would be sold to an organization involved simplest in components of the product portfolio — ensuing in the breakup of the unit and its 2,000 plus employees. an additional damaging result, as a minimum from his factor of view, would have viewed Nortel’s optical community disappear into the underbelly of a huge multinational.

“If we’d been purchased by way of a huge enterprise like Ericsson, Alcatel-Lucent or NSN (Nokia Siemens Networks), we would have been just a mere a part of a huge computing device,” DiPerna observes. “That’s not who we are.”

When Ciena prevailed within the bidding for Metro Ethernet Networks in 2010, DiPerna’s concerns weren’t wholly allayed. earlier than the telecom crash, Nortel and Ciena had competed directly in promoting optical methods. What if Ciena become buying Metro Ethernet Networks conveniently to strip it of know-how then shut it down?

Smith and Frodsham soon reassured him. all over the nuclear winter both establishments had concentrated on very different constituents of the optical expertise puzzle. while Nortel had targeting core, long-haul optical programs, Ciena had obtained many of the different pieces associated with excessive-velocity networking. whereas there turned into nonetheless some overlap, the businesses complemented each different greater than Diperna had expected.

This supposed merging the firms’ operations changed into slightly less complicated than it might had been, but the fees — and dangers — have been nonetheless giant. Ciena estimates it spent nearly $200 million on integration and restructuring prices ranging from consulting fees to severance fees. 

Nor was the financial system strong. Ciena’s revenues in 2009 had slipped to $653 million from $902 million the old 12 months and had been improving slowly. The loss in 2009 had topped $580 million in comparison to a outdated yr income of $39 million.

“The financial backdrop was fairly tepid,” Smith says, “so it took us a little longer than our preliminary plan known as for” to make the purchase of Metro Ethernet pay off.

indeed, Ciena misplaced cash for six straight years except 2015 when, finally, the enterprise posted a small earnings of $12 million on earnings of $2.4 billion. but the items are ultimately falling into vicinity.

along with its acquisition remaining year of Cyan — a California-primarily based networking application professional — Ciena’s items today direct traffic alongside the information superhighway’s densest routes. A consensus forecast prepared by Thomson Reuters suggests Ciena’s revenues will develop pretty much seven per cent this 12 months and 15 per cent in 2017 to reach an estimated $three billion, paced by means of expanded orders for speedier optical gear and linked application.

As Ciena continues buying other corporations, the relative contribution of the company’s 1,600 Kanata employees will lower a little bit. As of last October, the company employed 5,345 globally in comparison to four,300 in 2011. even so, there is little denying the significance of the Canadians inside the service provider.

The ancient Ciena and Nortel product strains have converged and the enterprise’s engineers are busy collectively reinventing networking technology in optical programs, utility and functions. The enterprise claims 70 per cent of its patents filed when you consider that it received Nortel’s Metro Ethernet Networks unit consist of as a minimum one Canadian inventor.

Ciena equipment is now processing video and information through optical fibre at speeds of 400 billions bits per 2nd — in are living networks the current state of the art is 200 gigabits.

“In challenging times we needed to decide upon and decide what we focused on,” says DiPerna, “but we certainly not took our eye off innovation.”


In Ciena, he discovered a corporation that has for 16 years maneuvered efficiently during the post-telecom crash and a world financial crisis — transitions that Nortel failed. He also discovered a firm willing to collaborate together with his engineers, and not deal with Kanata like a branch plant R&D shop.

Will the method proceed to work? This region has considered too many excellent screw ups in excessive-tech to answer this definitively. the sector is effectively too competitive. “here is no longer an business the place you let up,” Frodsham concurs.

When the excessive-tech world crashed after 2000, height annual earnings at Ciena slumped from $1.6 billion to less than $300 million. At Nortel, revenues within the optical unit collapsed from $10 billion to simply $1.5 billion. Losses at both operations were superb.

seen in this gentle, Ciena and Nortel’s optical neighborhood beat the odds conveniently by surviving. That they went on to jointly construct an organization that claims first or 2d spot in most of its product traces is all the more brilliant.

“individuals like readability if you happen to do these types of mergers,” says Smith, “We’ve invested heavily in R&D and run the company for the lengthy-time period — the effects have incessantly better.”

It’s the kind of steadiness and faith within the business’s personal skill that Nortel’s properly executives had abandoned all the way through their enterprise’s heyday. extra challenges loom as Ciena adapts its product traces to more software-intensive networks — more bendy techniques that depend much less on uncooked hardware. 

however this time DiPerna’s engineers are pushing the edges of technology while not having to fret even if their business is ready to implode. It’s a global of change from simply a couple of years ago.

HD-PacketExpert™ Multiport Ethernet Switch Tester supports BERT on all 12 or 24 ports. | killexams.com real questions and Pass4sure dumps

Press Release Summary:

Capable of handling multi stream traffic simultaneously, HD-PacketExpert™ Multiport Ethernet Switch Tester can generate traffic rate of 24 Gbps or 48 Gbps. Supporting RFC 2544 testing on 3 or 6 Port Pairs, product follows three steps for performing test analysis on multiport switches. Unit’s each port can generate mix of Layer2/Layer3 streams with different MAC/IP addresses and VLAN tags. HD-PacketExpert™ is compatible with Y.1564 based Ethernet Service Activation testing.

Original Press Release: Multiport Ethernet Switch Testing Made Easy!!

GL Communications Inc., announced today its solution for Testing Multiport Ethernet Switches for Functionality, Throughput and related parameters using GL’s HD-PacketExpert™ a versatile Ethernet based Testing Tool.

Speaking to the press, Mr. Jagdish Vadalia, a Senior Manager for product development of the company said, “High density Gigabit Ethernet Network Switches can have 12 or 24 ports, each supporting full bidirectional 1Giga bits/sec traffic rate, totalling to 24 Gbps or 48 Gbps rate simultaneously on all ports. To test such switches requires test equipment that is capable of generating traffic at the rate (24 Gbps or 48 Gbps) and analyse the traffic returned from the switch for errors.”

He added, “GL's High-Density versatile test equipment referred to as HD-PacketExpert™ facilitates the testing of Multiport Ethernet Switches with ease and accuracy. The Important test procedures are BERT, RFC 2544, Y.1564, and Multi stream UDP and TCP traffic generation and analysis.”

Mr. Vadalia further explained, “GL’s HD-PacketExpert™ helps Testing Multiport Switches in 3 Stages: To begin with Basic Bit Error Rate Testing (BERT) ,in this, Layer2/Layer3/Layer4 frames containing BERT payload of various frame sizes are sent at full line rate to each and every port of the switch. The forwarded traffic from the switch is received by HD-PacketExpert™ and analysed for Bit Errors, Pattern Sync etc. BERT testing represents a basic first level testing, making sure that the switch can handle full line rate on all the ports without dropping or corrupting even a single bit. HD-PacketExpert™ supports BERT on all 12 or 24 ports.”

He added, “Once the BERT process of the switches accomplished, next stage involves the testing of Throughput, Latency (Delay), Packet Loss (at different rates), and also ability to handle bursty traffic etc. RFC 2544 testing helps in testing and measuring the aforementioned test parameters. HD-PacketExpert™ supports RFC 2544 testing on 3 or 6 “Port Pairs” simultaneously i.e. RFC 2544 tests are conducted using Port Pairs.

The ability of the switch to handle multi stream traffic simultaneously is an important feature to be tested. When packets with multiple MAC addresses, VLAN tags, and IP addresses hit the same port, the switch has to process these packets and forward them correctly without introducing any impairment. HD-PacketExpert™ supports multi stream traffic generation on 3 or 6 ports simultaneously (up to 16 streams per port), at full line rate. Each port can generate a mix of Layer2/Layer3 streams with different MAC/IP addresses and VLAN tags. Using a remote loopback, the traffic is routed back to HD-PacketExpert™ and analysed for Throughput, Delay, Packet Loss and Packet jitter per stream.

HD-PacketExpert™ also supports Y.1564 based Ethernet Service Activation testing and multi stream TCP testing.”

    Facebook's new open networking switch 'overkill' for enterprises | killexams.com real questions and Pass4sure dumps

    Facebook's introduction of a design for building a scalable network switch using a common set of building blocks is the social media company's latest move toward flipping the source of innovation from vendors to technology users.

    Facebook unveiled its switch platform, called 6-pack, Feb. 11. Unlike proprietary switches, the technology is open, modular and not dependent on specific hardware.

    "We hope this is a platform that the entire industry can build on," the company said in a blog.

    6-pack is in production testing with Facebook's previously announced switching technologies. They include the bare-metal switching hardware, called Wedge, and a Linux-based operating system called FBOSS.

    Like its other  technologies, Facebook plans to submit 6-pack to the Open Compute Project, the initiative started by the social network in 2011 to share open server and data center designs with the general IT industry.

    Overkill for most enterprises

    Facebook, Google, Amazon and other operators of massive data centers have rattled the computer hardware industry by designing servers and networking gear to meet their specifications, and thus bypass traditional manufacturers.

    While such work can be innovative, some analysts view it as applicable only to the several hundred global companies with similar size data centers and IT budgets. Facebook's technology supports 1.4 billion users.

    Most organizations do not have data centers as large as Facebook's, so a modular design isn't necessary.

    "Generally, it's good to demonstrate what's possible, but it's very niche in terms of its applicability," Gartner analyst Joe Skorupa said about such efforts as 6-pack and Wedge. "Having them open source the design is significant and necessary, but greatly insufficient to move the market."

    Yet a company the size of Facebook releasing details on its cutting-edge data center may spur analysts and consultants to get networking professionals within conservative enterprises to think outside the box.

    "Enterprises get stuck in a rut and sometimes they won't look outside the market leader," Forrester Research analyst Andre Kindness said.

    Facebook's work is useful as a catalyst to get enterprises thinking differently. "It doesn't mean you have to do it, but you can challenge yourself," Kindness said.

    And hardware makers have taken note of Internet giants designing their own equipment. Hewlett-Packard and Dell, for example, have started selling some of their servers and switch platforms without their proprietary software, and Cisco Chief Executive John Chambers has said the trend has helped push his company toward more software innovation.

    Facebook introduced in November a network architecture comprised of modular components. Like Lego pieces, the components are part of the whole system, but each can be replaced or upgraded independently, so the social media company can launch services and increase network capacity faster.

    The design is meant to separate the hardware and software layers of the network stack to get more visibility into system operations, automate provisioning of services, and gain greater overall control.

    6-pack core technology

    6-pack, which Facebook calls the "core" of its network fabric, uses Wedge as a basic building block. It is a full mesh non-blocking, two-stage switch that includes six pairs of 12 switching elements, thus the name 6-pack.

    Each element can switch 1.28 Tbps, runs its own operating system on the local server, and is completely independent, Facebook said. The design lets the company modify any part of the system with no system-level impact to software or hardware. The elements, populated by 32 40 Gigabit Ethernet (GbE) ports, can be configured in two ways, depending on whether they are used for aggregation purposes.

    Each switching element contains a local control plane on a micro-server that communicates with a centralized controller. The elements use the same sheet metal shell, backplane and power supply, so they can be easily replaced or added, Facebook said.

    Enterprises prefer prebuilt technology

    Despite the benefits Facebook reaps from its development efforts, most enterprises prefer doing business with traditional suppliers, rather than cobbling together their own software and hardware based on specifications from an organization like the Open Compute Project, Skorupa said.

    "Unless it's widely available from someone who can actually build it, ship it, sell it and support it, it's tough to get [the technology] into the enterprise," he said.

    Most organizations do not have data centers as large as Facebook's, so a modular design isn't necessary. In addition, because of intense competition, vendors selling prebuilt systems are willing to negotiate pricing.

    "The need for modular switches is just a lot less," Skorupa said. "You have to get into very, very big scale before that starts to make sense."
