SDN Added to Interop Test

11:00 AM -- There'll be no getting away from software-defined networking (SDN) in 2013, especially if you attend any Carrier Ethernet or MPLS-related industry events this year. That much is already clear from the details of such events arriving in my inbox.

But that doesn't mean there won't be plenty worth checking out. The first item that's caught my eye for the early part of the year is the annual European Advanced Networking Test Center AG (EANTC) multivendor interoperability test, which takes place over a three-week period in the independent test lab's facilities in Berlin.

What's particularly interesting is that the EANTC team will be creating a test network that will include OpenFlow and Path Computation Element (PCE) solutions interfacing with non-SDN Carrier Ethernet and MPLS elements. The inclusion of PCE, an Internet Engineering Task Force (IETF) model that looks to be of particular interest to those building transport networks, is also interesting as it is often overshadowed in SDN architecture discussions by the OpenFlow protocol.

The key findings (but not including any that would be too embarrassing to the participating vendors) of EANTC's test will be presented at the annual MPLS & Ethernet World Congress event in Paris in March, which this year looks to be dominated by SDN topics.

SDN and network virtualization will also be a hot topic at the Ethernet Europe 2013 event in Frankfurt, Germany, in April. — Ray Le Maistre, International Managing Editor, Light Reading

re: SDN Added to Interop Test Well, the ONF's goal is to promote OpenFlow, so it is not an independent body. EANTC is an independent test lab -- the ONF, I'm sure, will welcome this test, as will the vendors and operators.-á
Of course, any work the ONF is doing to help interoperability between different elements is to be welcomed, but independent tests are always needed.-á

re: SDN Added to Interop Test

Wasn't ONF already doing this ? What value do these other forums bring ?

re: SDN Added to Interop Test Additional info on this -- according to the team at EANTC, vendors are keen to get their first carrier (non data center) SDN solutions into the public domain and this is a good step towards that, while service providers are interested because it will be the first "multi-vendor, SP-focused OpenFlow interop test event differentiating slideware from real implementations," according to EANTC managing director and Berlin club legend Cartsen-áRossenh+¦vel.
PCE was included in the 2012 test (with solutions from Cisco and MetaSwitch) but EANTC can't say yet which companies are providing what techs for this year's test, which takes place in EANTC's labs in Berlin -áFebruary 4-22.

I also took the opportunity to ask Carsten what his team's favorite movies of 2012 were. A mix of The Dark Knight Rises (latest Batman) and a selection of unidentified "obscure Japanese movies". Interesting!
