Arista Outpaces Cisco Again With FPGA Switch
March 27, 2012
Applications 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.Big Switch Unveils 'Open' SDN Architecture
March 20, 2012
Big 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.OpenFlow Nascent But Making Solid Progress
March 12, 2012
The 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.Brocade HyperEdge Promises To Ease LAN Management
March 06, 2012
Brocade 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.Cisco & Friends Debate Cloud Future
February 17, 2012
Cloud computing is evolving to the point where unique clouds will be developed for specific industry verticals, such as healthcare, government and financial services, predicts a Cisco Systems executive speaking at the CloudConnect 2012 conference this week in Silicon Valley. This runs contrary to what some have called the Coke versus Pepsi rule--that companies would not want to be in multitenant cloud environments with their competitors.Cisco's Rumored Quasi-Proprietary SDN Strategy Irks Some, Surprises Few
February 15, 2012
Cisco Systems' hint that it may introduce software-defined networking (SDN) technology that would not be based on the OpenFlow protocol prompted complaints from competing networking vendors and the OpenFlow community that Cisco was making another vendor lock-in play by offering proprietary technology, rather than standards-based products. Industry analysts say it's to be expected that Cisco would go the proprietary route as a way to preserve its industry-leading market share, and rival vendors are pushing open standards because that's the only way they can eat into Cisco's share.HP and Cisco Take Different Paths To SDN
February 03, 2012
News that Cisco Systems may release proprietary networking products implementing software-defined networking (SDN) technology, but not necessarily based on the emerging OpenFlow protocol, has executives at rival HP complaining about another Cisco vendor lock-in play. During a news event at HP Thursday, at which the company announced OpenFlow capability available for 16 HP networking product lines, executives were asked to comment on a news report from the Cisco Live event going on this week in London.Brocade ADX 12.4 Improves App Delivery
January 31, 2012
Brocade introduced a new application delivery controller that enables service providers to manage application delivery in a way that servers or endpoint devices no longer can. A key feature of the Brocade ADX 12.4 is what the company calls an OpenScript Engine, which enables enterprise service providers to build customized versions of network applications using the open-source Perl programming language to deliver networking capabilities unique to their needs.Riverbed Virtualizes Cascade
January 31, 2012
As use of IT grows in enterprises, so, too, do demands on networks to deliver more capacity and speed and to be able to prioritize traffic. Video gets priority over a simple email, but a VoIP call gets priority over video if the video in question is something frivolous on YouTube. The need to manage the growth and increasing complexity of networks is driving demand for network performance management technology that can monitor traffic, identify possible bottlenecks and intervene to clear bottlenecks up.How NetFlow Keeps Networks Running, People Alive
January 29, 2012
In all the technical discussions about network routers, switches, throughput, packets and the alphabet soup of acronyms that apply, it may be easy to forget that network downtime can have life-or-death consequences. For two NetFlow users, the requirements for the network monitoring technology were less dire, but the results were still compelling.
