Tuesday, March 5, 2013 at 3:24PM Part 2: Hardware for SDN
Netronome has demonstrated its flow processor chip implementing the OpenFlow protocol, an open standard implementation of software-defined networking (SDN).
"What OpenFlow does is let you control the hardware that is handling the traffic in the network. The value to the end customer is what they can do with that"
David Wells, Netronome
Wednesday, February 13, 2013 at 10:43AM The OIF's Carrier Working Group is assessing how software-defined networking (SDN) will impact transport. Hans-Martin Foisel, chair of the OIF working group, explains SDN's importance for operators.
Briefing: Software-defined networking
Part 1: Operator interest in SDN
"Using SDN use cases, we are trying to derive whether the transport network is ready or if there is some missing functionality"
Hans-Martin Foisel, OIF
Thursday, June 28, 2012 at 2:59PM OpenFlow may be causing an industry stir as system vendors such as ADVA Optical Networking extend the protocol's reach to the optical layer, but analysts warn that it will take years before the technology benefits operators' revenues.
"We see OpenFlow as an additional solution to tackle the problem of network control"
Jörg-Peter Elbers, ADVA Optical Networking
Friday, May 4, 2012 at 3:41PM Gazettabyte asked ADVA Optical Networking, Ciena, Cisco Systems and Ovum about their impressions following the recent OFC/NFOEC 2012 exhibition and conference.
OFC/NFOEC reflections: Part 2
"As the economy continues to navigate its way through yet another very difficult period, it was good to see so many companies innovating and introducing solutions."
Massimo Prati, Cisco Systems
Monday, December 19, 2011 at 6:25PM Gazettabyte asked industry analysts, CEOs, executives and commentators to reflect on the last year and comment on developments they most anticipate for 2012. Here are the views of Verizon's Glenn Wellbrock, Professor Rod Tucker, Ciena's Joe Berthold, Opnext's Jon Anderson, NeoPhotonics' Tim Jenks and Vladimir Kozlov of LightCounting.
Glenn Wellbrock, Verizon's director of optical transport network architecture & design
The most significant accomplishment from an optical transport perspective for me was the introduction of 100 Gigabit into Verizon's domestic - US - network.
"The key technology enabler in 2012 will be the flexible grid optical switching that can support data rates beyond 100 Gigabit"
Tuesday, November 2, 2010 at 9:23PM Briefing: Data centre switching
Part 2: Ethernet switch chips
Fulcrum Microsystems has announced its latest FocalPoint chip family of Ethernet switches. The Alta FM6000 series family supports up to 72 10-Gigabit ports and can process over one billion packets a second.
“Instead of every top-of-rack switch having a CPU subsystem, you could put all the horsepower into a set of server blades”
Gary Lee, Fulcrum Microsystems
