May 08, 2012OpenFlow and software-defined networking were on the agenda at Interop yesterday. But will they stand the test of time, or will SDN eventually become part of network management?
May 04, 2012Learn what to expect at Las Vegas Interop. Spoiler: Get ready for the cloud, virtualization and super switches.
April 27, 2012The concept of network virtualization seems to be gaining a lot of momentum across an industry that has virtualized most anything to do with IT. Can the same successes be applied to the networking market, transforming how systems communicate and revolutionizing infrastructure by abstracting the physical network from the demands of applications?
April 20, 2012Despite months of rumors and speculation, the networking industry's most powerful and influential vendor, Cisco Systems, is continuing to keep its plans for software-defined networking (SDN) largely to itself. In an exclusive interview during this week’s Open Networking Summit (ONS), Shashi Kiran, senior director of market management at Cisco, also an ONS member, says that OpenFlow and SDN are both so new that companies should not be deciding whether to use OpenFlow but rather how they can use OpenFlow along with other approaches.
April 19, 2012"SDN is ready to go," says Kaoru Yano, chairman of the Japanese tech giant NEC to his audience at the Open Networking Summit in Silicon Valley this week. At a conference last fall on software-defined networking (SDN), many presenters spoke of the promise of SDN to bring the same type of virtualization to the network that has made server and storage IT resources more efficient. This time, presenters such as Yano described actual implementation of SDN in production data centers. Although SDN has a long way to go before it’s anything approaching mainstream technology--and many cautions about it remain--it is making demonstrable progress.
April 18, 2012The telecommunications giant Verizon has joined with other top technology partners to collaborate on a software-defined networking (SDN) demonstration that is based on the OpenFlow protocol. The news of the collaboration was made at an Open Networking Summit being held this week in Silicon Valley.
March 27, 2012Applications and initiatives like private cloud computing, virtualization and mobility are placing increasing pressure on network infrastructure to be faster and more capable. Initiatives like software-defined networking and protocols such as OpenFlow can make the network more flexible and manageable, but they don’t really solve the problem of application performance where high-speed, low-latency requirements are the rule. Only by removing hops and their attendant latency from the network will we continue to see performance gains. Arista’s 7124FX switch uniquely puts customer programmable FPGAs at the edge of the network for microsecond application processing.
March 20, 2012Big Switch Networks, which is considered an early leader in the push for software-defined networking (SDN) based on the Open Flow protocol, is putting its own stake in the ground, declaring its commitment to open standards in developing new technology to bring virtualization to networking environments. This week, to mark its second anniversary, the company announced its Open SDN (a trademarked term) architecture based on 'three pillars' of open standards, open APIs and open source.
March 12, 2012The OpenFlow protocol for enabling software-defined networking has made progress, but to analyst Rohit Mehra, it’s still more of a concept than a reality. At last week's IDC Directions 2012 conference in San Jose, Calif., he tried to put the buzz about OpenFlow in perspective.
March 06, 2012Brocade has announced a new initiative to simplify switch configuration and management. HyperEdge lets IT professionals designate a master switch that can manage all other switches on the LAN. Brocade HyperEdge is a response to Cisco, Juniper and other vendors that are offering simplified management. HyperEdge software creates a virtual stack of Brocade's ICX and FCX switches, allowing IT to manage tens or hundreds of devices as a single logical unit. HyperEdge should ease multidevice management and provide a clear upgrade path from low-cost edge switches to higher-cost, more capable products. While Hyper Edge should be welcome news to Brocade customers, it won't be available until the first quarter of 2013.
