Alcatel-Lucent Wednesday delivered a virtual IP area router that makes use of its usual working system to fulfill service cloud carrier wants, with the goal of enabling network operators to bring features to market rapidly.
The Alcatel-Lucent Virtualized service Router announcement follows a similar stream by means of Juniper Networks closing week to highlight its virtualized MX collection 3-D aspect router, which Juniper referred to is designed to assist carriers and organizations pace provider deployments.
Alcatel-Lucent and Juniper are among machine providers joining a tiny however quickly-starting to be community of suppliers rolling out service-grade virtual part routers to network operators.
"we've been looking forward to a year and a half for big router organizations to lay out their software routing product strategy, and now Juniper and Alcatel-Lucent, while taking distinctive strategies, have each announced v-router items," spoke of Infonetics research co-founder Michael Howard. finally all router vendors, together with Cisco and Huawei, will need to roll out v-router recommendations, Howard brought, notwithstanding doing so may cannibalize their existing hardware product lines.
a brand new Infonetics forecast estimates the digital router marketplace for community operators will be a slim $2.5 million with the aid of the conclusion of 2014. however in 2015, Infonetics tasks the v-router market to develop to $21 million.
"provider suppliers had been awaiting these, so we suppose this is a market ready to delivery," Howard referred to.
nevertheless, provider providers plan to do lots of testing during this new market section.
"I feel that in definite overlaid digital environments, there's a good use case for virtualized routers running on hypervisors, however I do not believe they'll exchange all intention-constructed routing hardware any time in the foreseeable future," pointed out Christopher Davis, NTT Communications senior director advertising Americas, in an electronic mail.
"The capacities we require for our core and edge networks, not to point out operational excellence, are critical to the success of our enterprise. Our R&D teams, IP engineers and product development groups proceed to research, look at various and consider router alternatives and configurations (like digital), as neatly as the providers supplying them, while giving full consideration to the necessities contributed to us by way of our purchasers," he brought.
Alcatel Lucent wants to supply customers the flexibleness to move right into a greater cloud-centric atmosphere, as a result of a cloud these days is well-nigh a knowledge center full of racks of servers, noted Manish Gulyani, Alcatel-Lucent vice chairman for IP routing product advertising and marketing. "What they [operators] would care to do is observe that philosophy of deploying apps to networking and to be able to run some of their key community features as purposes of their records facilities."
In 2015, Infonetics tasks the v-router market to develop to $21 million.
Alcatel-Lucent based mostly its v-router requisites on feedback and tips from provider suppliers that began the network services virtualization (NFV) workgroup, Gulyani spoke of. The message became that they necessary to alternate the way they design and operate networks and bring functions if they are to stay critical in the cloud world, he said. Alcatel-Lucent's answer become to decouple the application in its area router hardware and make it accessible as a application-simplest software that runs on Intel x86 servers.
Alcatel-Lucent is the use of its carrier Router working gadget as the foundation of its v-routers, which runs across its entire portfolio of aggregation, aspect and core router items. "We rearchitected it to get essentially the most out of this new means of scaling up," Gulyani referred to.
"You deserve to use definite platform and application suggestions to benefit from this new flexibility. we will push the boundaries of scale each in control airplane efficiency and on the statistics aircraft facet."
as a result of most of its valued clientele don't seem to be constructing new networks, Alcatel-Lucent prolonged its operations atmosphere with end-to-end management using the same equipment customers use for its hardware-based products. "We labored to have in mind digital machines and IT services so our management device looked and felt like an software," Gulyani referred to.
This doesn't suggest virtual facet routers will substitute purpose-developed hardware, Gulyani mentioned. in its place, community operators can use digital area routers especially for purposes more desirable ideal to a virtual foundation.
"offering virtual routers on the community part makes feel as a result of it is the place you say what IP traffic is for which consumer. this is why we accept as true with an side platform makes feel to carry into the digital world some subset of functions," he said.
Gulyani talked about Alcatel-Lucent has confirmed one hundred sixty Gbps throughput on a single x86 server, a velocity in an effort to "supply individuals the agility to introduce carrier quickly and scale it up to greater capability by using adding more instances of purposes running on greater servers."
Alcatel-Lucent mentioned two carrier suppliers have already deployed the new v-routers, with 20 more within the procedure of trying out them.
"Now carriers have the option to purchase the packaged router code to run on servers for facet router applications," Infonetics' Howard stated. "A yr from now, the landscape of who's enjoying within the virtual routing house in service labs will be relatively glaring. however at the moment, or not it's no longer absolutely clear what the carrier-grade routing carriers are doing."
Neither Alcatel-Lucent nor Juniper has launched virtual part router pricing information.

If your virtual private network (VPN) leaks, there’s no point in even turning it on.
You might as well take that monthly fee and hand it to a random person on the street. We’re not kidding. The reality is that a lot people use VPNs today - overall usage increased to 26% in 2018, making this tool one of the fastest technical adoptions in recent memory. But are they using it correctly?
The joke, and it’s a bad and frequent one, is on anyone who turns on their VPN without checking it for data leaks.
An improperly configured service can leave you vulnerable to WebRTC leaks or DNS hijacking (more on these later). Either is essentially an engraved invitation to any passing hacker to jump into your life and screw it up. Luckily, there is a quick way to check if your VPN is, in fact, broadcasting your whereabouts. More on that later too.
The Weak Link in the Chain
You might have already noticed that the internet is inherently insecure, and we’re not talking about emotional issues. In the early days, it was designed to reliably send data chunks called packets anywhere in the world, rerouting itself around failed connections as needed.
In other words, the online environment was built for adaptability, not security. By the time anyone thought it might be a good idea to implement privacy protocols, hackers already had a strong toehold. One of the most recent and promising tools to try to take back control are VPNs, which work great.
Except when they don’t.
While a VPN connection is active, websites and outside entities should never be able to detect the true IP address assigned by your ISP. However, this is not always the case due to a known deficiency within browsers like Google Chrome and Mozilla Firefox which can lead to an issue known as WebRTC leaks.
Many of the most popular websites in the world rely on WebRTC, which stands for Web Real Time Communication, to populate webpages with dynamic content that can be updated live without reloading. This type of data is transmitted through a different mechanism than traditional HTTP traffic.
WebRTC leaks occur at the browser level when a website is able to expose a user's source IP address while bypassing the VPN protection. When this happens, you no longer are truly anonymous online and could have private information exposed.
If a cyberattacker is able to retrieve your true IP address through a WebRTC leak, it means they may be able to determine your geographic location or even infiltrate your local network. The worst case scenario is a type of attack known as DNS hijacking, which leaves your entire network at risk.
All computers, including “smart” devices and wearable tech, rely on the Domain Name System (DNS) to help translate web URLs into IP addresses. That information is what allows data on the internet to be routed so quickly. Each time you load a webpage in your browser, the computer checks DNS to find out where to send the request.
When hijacking the DNS, the hacker changes your device's DNS settings and intercepts - or redirects - all outgoing traffic. As a result, you might open a bookmark or type in the URL of a common website, but instead of loading the correct content, your browser will point to a rogue webpage that seeks to steal your personal information.
Such was the case in a recent attempt by cyberattackers to hijack the domain names of several U.S. government websites.In the wake of the attacks, the US Department of Homeland Security (DHS) issued an emergency directive tightening DNS security.
Testing VPN Vulnerabilities
If you are concerned about the possibility that your VPN client is leaking your primary IP address, then you need to be proactive about testing its vulnerability. Otherwise, it might be too late and a hacker could already be intercepting your web traffic and using it for nefarious purposes.
Many tools are available online that will simulate WebRTC traffic and let you see whether your VPN client is vulnerable. A popular one is the BrowserLeaks website, which will show you whether your current browser supports WebRTC connections and what IP addresses are shared.
If you run the test and see your ISP's address and country listed in the "Public IP Address" section, then it means you are affected by a WebRTC leak. Since these leaks occur at the browser layer, make sure to run the test in every browser that your operating system supports.
For Google Chrome users, there are third-party plugins available, like WebRTC Control, which can quickly test your system for WebRTC leaks and let you deactivate such connections. Just be sure any plugin you download is from a reputable developer, as these tools could actually be disguised by hackers looking to install malware on your computer.
For protecting against DNS leaks, the best tool to use is DNSLeak.com, which will check your current IP address and then let you run a diagnostic tool to check your current DNS servers. If your DNS server addresses differ from your VPN's IP address, then your settings may have been hijacked. At that point, it's important to quickly reset your DNS addresses using a free, safe service like Google DNS.
Finding a Reliable Service Provider
VPN's typically involve a monthly or yearly cost and are somewhat more expensive than your regular ISP provider - and, yes, you will need both.
Therefore, you have a right to ensure that the product is doing what it claims to and delivers true protection and anonymity online. If that's not the case, then it is time to move on to a different solution.
Cyberattacks continue to evolve, so even if your VPN passes leak tests in its current state, you must continue to watch for new threats while keeping your VPN software up to date.Join the newsletter!

Alcatel-Lucent has launched Nuage Networks, an SDN company that will offer automated provisioning of virtual networks across data centers, as well as integration into a larger cloud orchestration framework.
Rather than building an SDN system centered on Alcatel-Lucent hardware, Nuage's vendor-neutral technology is using OpenFlow controllers to direct virtual switches and routers on software overlay networks with open application programming interfaces.
"Openness is a key pillar in the premise of software-defined networking," said Sunil Khandekar, CEO of the SDN company. "Nuage Networks' SDN solution virtualizes and automates any existing data center infrastructure … that includes working with the data center operators' existing network equipment of choice, as well as their desired servers, hypervisors and compute orchestration environment. Nuage Networks assumes no dependency on hardware, including Alcatel-Lucent hardware," he said.
Nuage's software-defined ecosystem includes an OpenFlow-based controller, extensions of the Open vSwitch for virtual routing and switching, and a platform that acts as a services directory and policy engine. With the combined technology, engineers can dynamically instantiate virtual network segments in response to the needs of applications and migrating virtual machines (VMs).
"Compute and storage are virtualized, but the network gets in the way. It's not dynamic; it's cumbersome … [so] a fundamentally new model is in order," Khandekar said.
With the SDN company's technology, engineers establish rules and policy for provisioning network infrastructure using the Virtual Services Directory platform. The policy engine relies on a combination of network analytics and programmed rules to grant role-based permissions based on any number of factors, such as hierarchy of need.
Based on these rules, the Virtualized Services Controller sends messages to the Virtual Routing & Switching platform to create network segments and direct flows appropriately. "Nuage detects the creation or deletion of [a VM]. Then it queries the SDN controller to see if there is a policy already established in the directory for that tenant. If the rules have been set, network connectivity is established right away," said Houman Modarres, senior director of product marketing at Nuage.Does Nuage solve the problem of intercloud networking?
Enterprises and cloud providers have found plenty of innovation in networking within their own virtual stacks and clouds. But they're often unable to extend that networking, with all of its routing, switching and Quality of Service, or QoS, policy, across private and public cloud domains.
"The real problem for operators is to help the data centers become part of the WAN and carrier network, as opposed to being separate nodules attached [to] the WAN," said Michael Howard, principal analyst at Infonetics Research.
Nuage tackles that challenge by using IP networking to peer routers at the edge of any data center, which essentially extends network overlays -- or virtualized Layer 2 -- across data center domains through a virtual private network, or VPN. Network policies can be implemented across multiple tenants, but also across data centers and hybrid clouds, for example.
"Our VM controller is federated using IP protocols, and this is the reason why we are able to seamlessly peer any router at the edge of the data center and provide connectivity," Khandekar said. The idea is to "stretch the control plane" across multiple network domains so "automation is consistent across data centers," he said.
The SDN company's system can be integrated into any cloud orchestration system, including those from VMware, CloudStack and OpenStack. It can also work with any network overlay protocol, including VXLAN [Virtual Extensible LAN] and NVGRE [Network Virtualization using Generic Routing Encapsulation]. That means that networks can be provisioned and managed in the same context as compute and storage, allowing for an even grander federation of management, according to Howard.
In his vision of the ideal future network, there will be a controller that directs "a bunch of different types of controllers; for example, one for consumer broadband, one for global backhaul or mobile packet core," Howard said. The Nuage federated controller system is a first step toward that vision, he said. "The major goal is to have a global view of the multilayer and multivendor network, and to be able to provision services they run across different [segments] of the network with some kind of orchestration of controllers," he added.
Nuage also integrates Layer 4-7 services into this automated provisioning by working with an ecosystem of partners, including Palo Alto Networks and F5, to place virtual instances of application-aware firewalls and load balancers into the mix. Generally, when new applications are created, they need to be manually connected to a firewall and load-balancing capability, but in the SDN company's system, those functions would become part of the orchestration and automation, Modarres said.
Trials of the Nuage Networks Virtualized Services Platform begin in May with beta customers, including U.K. cloud service provider Exponential-e, French telecom service provider SFR, and the University of Pittsburgh Medical Center. Worldwide commercial availability is planned for mid-2013.
In this design, the Azure Firewall will be deployed once into a hub virtual network. Applications or services will be deployed in spoke virtual networks. VNet peering (global peering is not supported), will connect the hub, where the firewall is hosted, to the peers, where the applications/services are hosted.
The benefits of this design are:
Deploying Azure Firewall into a hub & spoke virtual network architecture [Image Credit: Aidan Finn] Firewall Virtual Network
This is a very simple virtual network – a single subnet, that must be called AzureFirewallSubnet, is required to host the Azure Firewall. The firewall has a single public IP address, which you should note for the “destination address” in NAT rules, and a single internal IP address, which you should note for creating route tables in the application/services subnets.
If your applications will be internet facing and they require a dedicated public IP address (see web application gateway/firewall), then traffic from the Internet will come into those services without flowing through the firewall. However, traffic between applications must flow through the firewall, and this level of isolation will contain risks and enable full logging with centralized oversight & control.
NAT rules will allow you to present applications to the Internet via the PIP of the firewall. Application and/or network rules will allow you to control the flow of traffic between the subnets and out to the external world.Application Virtual Network(s)
There are three things to consider here:
You will do a lot of routing management if you choose to deploy Azure Firewall, and you will do massive amounts of routing management if you deploy the Azure Firewall into hub-and-spoke architecture. This is, so far, where I have spent most of my network troubleshooting time – usually it’s a route table that I have forgotten to associate with a subnet.
If you create a route table for each subnet with a simple route to 0.0.0.0/24 via the internal IP address of the Azure Firewall. It would appear that all traffic will route via the Azure Firewall, but in reality:
In reality, you will need greater control. One could create a route with a destination of 10.0.0.0/16 via the internal address of the Azure Firewall. That route will direct all traffic inside the VNets through the firewall but allow services to respond out through their respective inbound routes. However, this micro-segmentation will send all traffic across the peering connections and that could increase network costs substantially.
A balancing act will be to send all inter-VNet traffic through the Azure Firewall but leave all intra-VNet traffic to stay inside the VNet – and still be filtered by the NSGs. To do this, you will need more complex route tables. Each route table will need a route for each VNet or subnet that it must communicate with. For example, the route table on 10.1.1.0/24 might have a route to 10.2.0.0/16 that passes through the Azure Firewall’s internal IP address.VNet Peering
The final piece of the puzzle is VNet peering. Each application VNet has peered with the Azure Firewall’s hub VNet. You should consider a few things here:
If you require a bastion host to enable secured remote access to your virtual machines then place it into another spoke virtual network. You should then allow traffic from it to the other subnets using network rules in the Azure Firewall. Here are two things to think about:
