Transport SDN

Telefónica Steps Closer to Transport SDN

Telefónica has taken a step closer to a programmable transport architecture with a field trial of SDN capabilities involving commercial traffic. The trial took place in Peru.

The operator and its technology partner, Huawei Technologies Co. Ltd. , are claiming this as an industry first and will continue to develop the Chinese vendor's SDN IP+Optical solution -- including ROADM, OTN switching and router hardware and SDN controller and orchestration software -- for commercial deployment.

The aim of the partners is to build programmable networks that can adapt to the service requirements of an operator while reducing costs and improving overall operational efficiencies. Telefónica SA (NYSE: TEF) group CTO Enrique Blanco has stated that the development of an efficient, flexible transport network is critical to the operator's 5G strategy and is one of the first challenges that needs to be successfully overcome as Telefónica prepares to manage increasing volumes of video and data traffic.

It has taken a lot of tests and trials to get to this point, though. Telefónica and Huawei announced the completion of "SDN-based IP and Optical synergy" lab tests in March 2014 and issued a joint press release about its first field trials in March 2015. (See Telefónica Tests Optical/IP SDN With Huawei.)

Many major operators are aggressively transforming their transport networks to become more agile, gain a competitive edge and eventually reduce costs but there are a number of ways to reach those goals, as a Heavy Reading report, Programmable Transport: Use Cases Emerge as Capability Improves, noted late last year.

Re: Closer and closer.... Multi Vendor IP & Optical Integration True comment Ray. As most carrier networks have more than one vendor in their IP and optical infrastructure, the multi-vendor part is important. Can't avoid mentioning that only Seodna Systems have already demostrated multi vendor SDN integration of IP and optical.

Re: "claiming this as an industry first " I hope we'll be at a place soon where being first is less important than getting it right. I think carving out milestones means less to network operators than to their vendors, but in general, the whole telecom segment is currently at risk, so being first may mean you are outrunning your friends as you all try to escape the bear.

"claiming this as an industry first " Not even close.

Closer and closer.... It will take some time but once we have a body of operators that can finally achieve the long-talked about benefits of SDN (and NFV) then we'll really found out all the unknown advantages (and challenges - security still being a big one...)

BUT -- there's always a but -- this has been a lot of time coming with an operator working with one vendor. is the multi-vendor open/swappable nirvana just not giong to work out in the big wide transport world? Or is that just a CPE dream (if that)?
