Ciena and partners build SDN testbed for carriers 

Ciena, working with partners, is building a network to enable the development of software-defined networking (SDN) applied to the wide area network (WAN). The motivation in creating the testbed network is to boost carrier confidence in SDN while aiding its development.

 

 "When you get very serious vice presidents in tier-one carriers saying, 'This [SDN] is the biggest change in my career', there is something to it."

Chris Janz, Ciena
