LAS VEGAS -- HP says it has all of the necessary orchestration tools for its software defined networking strategy - the big question is, will it build its own controller?HP Networking officials wouldn't say. Currently HP OpenFlow-enabled switches interoperate with controllers from various vendors, as demonstrated in the OpenFlow Lab on the Interop exhibition floor. But HP wouldn't say if it will stick to this route or roll its own. Hot Products at Interop 2012THE NEXT-GENERATION ENTERPRISE?: OpenFlow, Software-Defined Networking and the Enterprise WAN"We can't comment on too forward looking (developments) but controller is part of a larger picture for an offering in SDN, no question" said Bethany Mayer, senior vice president and general manager of HP Networking. "That's about all I can say."HP Networking CTO Saar Gillai expanded on it a little bit, hinting that SDN control does not just involve the company's networking gear."We see the control plane as not just a networking thing in … [Read more...] about HP has all the Ingredients for Software Defined Networking, Almost

This vendor-written tech primer has been edited by Network World to eliminate product promotion, but readers should note it will likely favor the submitter's approach.Software-defined networking (SDN) is emerging as an alternative to proprietary data center networks, a way to separate the control plane from the data plane in data center switches and routers. With SDN, network control is implemented in software and can be executed from a server, which reduces network complexity and provides a common interface that is an alternative to vendors' proprietary and expensive options.There are several developments of SDN solutions, with OpenFlow (in its early stages) and OpenSM (in production today) being the two leading options. OpenSM is the SDN solution for InfiniBand, a fast interconnect technology that was built as an SDN from its basic architecture level and used in the most demanding production sites in existence today.ANALYSIS: What are the killer apps for software-defined networks?SDN … [Read more...] about InfiniBand: The Production Software-Defined Networking (SDN)
The network team is being bombarded with configuration requests that can take days or weeks to handle, but luckily several approaches are emerging that promise to increase network agility, chief among them Network Virtualization (NV), Network Functions Virtualization (NFV), and Software Defined Networking (SDN).The alphabet soup may seem overwhelming at first, but each of these approaches is trying to solve different subsets of the macro issue of network mobility. In this article we’ll examine how NV, NFV and SDN differ and how each moves us down the path toward programmable networks.Network VirtualizationEnterprise networking administrators can’t keep up with requests for network changes. There needs to be a way to automate the network to improve IT’s responsiveness to change. In this use case, we are typically trying to solve one problem: How do I move VMs across different logical domains? Network virtualization literally tries to create logical segments in an … [Read more...] about Understanding the differences between Software Defined Networking, network virtualization and Network Functions Virtualization
Software defined networking applies the abstraction concepts of hardware virtualization to networking infrastructure. This works well for cloud implementations, which need significant configuration and planning. But SDN and network virtualization may still be too immature for prime time.Software defined networking is one of the most misunderstood concepts in infrastructure computing. It's a phenomenon that's growing in relevance, but it's still mysterious to many CIOs, particularly those who were not reared in overly technical practice. Many myths still surround SDN. What exactly is the notion behind the technology? How can you apply SDN at your business? And how can your organization benefit from it. Software-Defined Networking BasicsEssentially, SDN takes the virtualization phenomenon that's been sweeping datacenters around the globe for the past several years and extends it from computing hardware and storage devices to network infrastructure itself. By inserting a layer of … [Read more...] about What CIOs Need to Know About Software Defined Networking
SDN (software-defined networking) promises some real benefits for people who use networks, but to the engineers who manage them, it may represent the end of an era.Ever since Cisco made its first routers in the 1980s, most network engineers have relied on a CLI (command-line interface) to configure, manage and troubleshoot everything from small-office LANs to wide-area carrier networks. Cisco's isn't the only CLI, but on the strength of the company's domination of networking, it has become a de facto standard in the industry, closely emulated by other vendors.

Software-defined networking (SDN) is a way to virtualize networks for ease of configuration and maintenance in the same way that servers and storage are being virtualized. The difference is that SDN as a network solution is not nearly as far along as virtualization in the server and storage worlds.Nevertheless, SDN is coming — and the more IT decision-makers and business leaders know about it, the better they'll be able to determine where and when to introduce it to their data centers. Here are 10 of the questions they're asking about SDN.Like the server hypervisors used in virtualization, SDN introduces a layer of software between bare metal network components and the network administrators who configure and set them. This software layer gives network administrators an opportunity to make their network device adjustments through a software interface instead of having to manually configure hardware and actually physically access network devices.There are two planes in … [Read more...] about 10 key questions about software-defined networking
It's acommon trend among writers and filmmakers to offer up their particular take ona theme such as mistaken identity, opposite attraction or revenge. Similarly,the technology realm is populated with vendors offering their own blend of acommon concept such as a Linux distribution, handheld tablets or networkingtrend.Unlikefictional stories, where genuinely new plots are excruciatingly difficult tofind, new advances in technology continually open new possibilities as well asmarkets for vendors who demonstrate evolutional agility (of course, one mightargue that "new themes" such as cloud computing and thin clients are justrecycled topics from the past).One such example in the networking realm is software defined networking, or SDN. It's arelatively young concept that was projected in 2012 by the market intelligence companyIBC to become a multi-billion dollar industry in 2016. Well, wouldyou like the technical answer or the functional answer? Let's start with thefirst option. … [Read more...] about Software Defined Networking: The Cisco approach
The need for greater agility and control in the networking realm in order to manage environments more effectively has produced evolutionary advances over the past few years. One such example is Software Defined Networking (SDN), which offers the next step in network traffic control, whereby software and policies are used to define consistent network behavior and responses, rather than individual hardware device. For instance, SDN can direct network traffic to least-used resources in a load balancing arrangement so that Take Tech Pro Research's survey on Software Defined Networking and share your input for the upcoming research report. The topic of SDN was covered in-depth on Tech Pro Research three years ago via a survey and subsequent research report. The report indicated that at least half of respondents had no knowledge of the topic of SDN, showing it was a burgeoning concept that hadn't reached all audiences.
