Avaya takes a unique approach to ease the pain of SDN migrations

In the movie, Star Trek V: The Final Frontier, Spock's older brother, Sybok, had telepathic abilities and he could feel people's pain by touching them. In the movie he would say, "share your pain with me and gain strength from sharing." Sybok was a deeply religious Vulcan and, in the movie, sought out to find "Sha Ka Ree," the Vulcan equivalent of Eden, where everything began. Nirvana, if you will.In the networking industry, software defined networks (SDN) are supposed to bring the networking equivalent of Sha Ka Ree. However, I don't need to be a Vulcan telepath to understand customers' pain when it comes to SDNs. Almost every network professional I talk to today has an interest in SDN. However, the majority of businesses feel that deploying a software defined network is too complicated.To read this article in full or to leave a comment, please click here

HP has joined the disaggregation party through two partnerships that will produce a branded white box switch capable of running multiple network operating systems.HP has expanded a relationship with Accton Technology to offer two new switches initially, and more later this year. The switches will be low-cost, software-independent white box hardware targeted at Web scale data centers supporting cloud, mobile, social media and big data workloads.Under a second arrangement, HP will offer Cumulus Networks’ Cumulus Linux network operating system on the Accton switches. Cumulus Linux runs on a variety of white box and branded switching hardware based on merchant silicon, and is intended to make the software side of networking hardware independent.To read this article in full or to leave a comment, please click here

Brocade improves data center agility with new VDX fabric switch

While the networking industry has gone crazy over software defined networks (SDNs), Brocade has been one of the few vendors that have continued to evolve their fabric portfolio. Customers looking to improve the agility and level of automation do not need to make the jump to an SDN – instead, an Ethernet fabric can be used to accomplish these goals and provide an excellent foundation for a future SDN deployment.Earlier this month, Brocade announced a new fabric switch, the VDX 6940. The new switch set the current high water mark in the industry with respect to port density for a fixed form factor switch. The 6940-36Q is a 1RU switch with 36x40 Gig-E connections or 144x10 Gig-E connections (assuming breakouts are used). The 6940-144S is a 2RU switch with 96x10-Gig-E ports and either 12x40 Gig-E or 4x100 Gig-E ports. Both switches have a massive amount of capacity, making them ideal for on-demand scaling of a fabric by adding capacity to a spine horizontally as the number of leaf switches increases.To read this article in full or to leave a comment, please click here

Talented startup aims to deliver software defined cloud

One of the ways you can tell that software defined networking (SDN) has the power to change the vendor landscape is by the number of startups that have emerged. Over the past few years, we've seen startups pop up to address the evolution of the data center and the WAN. For this reason, I always tend to keep my eyes open for companies generating buzz in the marketplace in this area. In my recent travels, I was made aware of another "stealth-mode" startup that's building a solution to address a new use case for SDNs. According to its website, Avni Networks addresses the "transformation of the Data Center to Virtual Clouds for the Applications Economy." From what I can tell, there seems to be some buzz around what this company is up to, which made me curious about learning more.To read this article in full or to leave a comment, please click here

Cisco’s Nexus 9000, ACI customers grow

Cisco now has 1,700 customers for its Nexus 9000 switch and over 300 for its APIC controller, the central element of its Application Centric Infrastructure (ACI) programmable networking and SDN strategy. This is up from 970 and 200+, respectively, in the company’s fiscal first quarter.The number of ACI/APIC customers compared to the number of Nexus 9000 customers – Nexus 9000 is the hardware underlay or foundation for ACI – might seem underwhelming at first blush: only 20% were ACI customers in Q1 and less than 20% in Q2. But APIC just started shipping August 1, Cisco says, while the Nexus 9000 has been shipping for almost a year.To read this article in full or to leave a comment, please click here

Arista says it can route VXLAN too, just like Cisco

Cisco’s claim that its Nexus 9000 leaf switches have a VXLAN routing advantage over those based on Broadcom Trident II silicon is meeting some resistance. In announcing support for the BGP EVPN control plane for VXLAN on its Nexus 9000 switches, Cisco said its Nexus 9300 leaf switches, equipped with Cisco’s custom ALE ASIC, can route VXLAN overlay traffic, which the company touts as a benefit over Broadcom Trident II-based platforms from competitors.To read this article in full or to leave a comment, please click here

Why the SteelApp sale is a win-win for Brocade and Riverbed

Last week, Brocade announced its intent to purchase the SteelApp product line from Riverbed for an undisclosed amount of cash. SteelApp is a virtual application delivery controller and competes most often with the likes of F5 and Citrix. Formerly known as Stingray, SteelApp came to Riverbed in the acquisition of UK-based Zeus, who pioneered the virtual ADC market. On paper, the acquisition made sense for Riverbed, as Zeus had solutions that optimized the performance of applications with a data center solution and Riverbed was a vendor that optimizes application performance over the wide area network.However, although the business unit had some early success when it was dropped into the Riverbed channel, it never really became a meaningful part of Riverbed's revenue stream. Now, after almost four years, SteelApp will become part of Brocade's business.To read this article in full or to leave a comment, please click here

How network admins can survive SDN

With the advent of SDN, there’s been a lot of speculation about the future of the network administrator.Some doomsayers predict the network admin will be obsolete as network virtualization becomes the responsibility of the server or systems admin already in charge of server virtualization. Or that as SDN applications take on more network intelligence in order to program what network resources they need, the application developers might take over the role of network admin.To read this article in full or to leave a comment, please click here

The SteelApp product line controls traffic to and from applications to improve application delivery.To read this article in full or to leave a comment, please click here

Cisco offers ACI alternative for Nexus 9000 switches

Cisco is adding a new control plane capability to its Nexus 9000 switches for customers not yet opting for or needing a full-blown application policy infrastructure.Cisco’s BGP Control Plane for VXLAN is designed to appeal to operators of multitenant clouds looking for familiar BGP routing protocol features with which to scale their networks and make them more flexible for the demands of cloud networking. VXLAN, which scales VLAN segmentation to 16 million endpoints, does not specify a control plane and relies on a flood-and-learn mechanism for host and endpoint discovery, which can limit scalability, Cisco says.To read this article in full or to leave a comment, please click here

Dell celebrates disaggregation’s first anniversary

Dell is celebrating the first anniversary of its Open Networking initiative, an effort to offer customers a choice of operating systems and applications on standard, merchant silicon-based hardware.Dell was one of, if not the first major vendor to disaggregate switching – separating the interdependencies of hardware and software so customers, in this case, can run a variety of operating systems on Dell switches. Juniper followed suit with an Open Compute Platform-based switch that can run its Junos operating system, or another that’s ported to the OCP-based hardware.To read this article in full or to leave a comment, please click here

IDG Contributor Network: It’s my network and I’ll binge watch if I want to

In my first blog post I discussed the gap that exists between what consumers want and what the network can feasibly provide – what I referred to as the "agility gap." In just the four months since that post, we have seen a variety of new examples of the acceleration in technology advances for the consumer and end user, while the network chugs along trying to keep up.The most intriguing of these was Sony's unveiling of PlayStation Now at CES 2015, a cloud-based gaming subscription service that gives players unlimited streaming access to more than 100 games.To read this article in full or to leave a comment, please click here

The Layer 2-3 Ethernet switch market is expected to exceed $25 billion in 2019, a compounded annual growth of over 2% from 2014, according to Dell’Oro Group.Data center switching will drive most of the growth in the market.  Data center switching growth will be driven exclusively by the cloud, with the enterprise market declining slowly, towards the end of the decade, Dell’Oro expects. MORE ON NETWORK WORLD: Will enhanced servers do away with the need for switches?To read this article in full or to leave a comment, please click here

Viptela brings Software-Defined WANs to the enterprise

This column is available in a weekly newsletter called IT Best Practices.  Click here to subscribe.  In April 2014, Zeus Kerravala wrote in Network World that the software-defined WAN (SD-WAN) is now a business imperative. He cites several reasons why the time is right for companies to reconsider their WAN architecture.First of all, cloud and mobile computing, as well as applications such as video and voice over the network, are creating vastly different traffic patterns than the old style of client/server computing. Next, business agility is the enterprise mantra today, but traditional WAN architectures are too inflexible to enable the much-needed application agility. And last but not least, the complexity of the WAN makes it increasingly difficult to make even small changes in a reasonable timeframe.To read this article in full or to leave a comment, please click here

The first place to tackle SDN? In the WAN

Disruptive innovation in infrastructure is on the rise, and nowhere is that more evident than in the Software Defined Networking movement. But while much of the SDN discussion has focused on the data center, the better initial use case might be in the wide area network. One advocate of that approach is Michael Elmore, IT Senior Director of the Enterprise Network Engineering Infrastructure Group at Cigna, a global health service company headquartered in Bloomfield, Connecticut. Michael is also on the board of Open Network Users Group (ONUG). Network World Editor in Chief John Dix asked Elmore to participate in an email-based Q&A to explore the promise of Software Defined WANS.
