5. Nuage Networks' Virtualized Services Platform
Alcatel-Lucent's SDN arm, Nuage, made a splash in the burgeoning SDN space when it unveiled its Virtualized Services Platform, a software overlay for data center networks. The value of VSP, Nuage said, is that it helps automate and accelerate the connection of virtual machines to data center networks after those machines are instantiated. Nuage said VSP works by essentially creating “tunnels” between virtual machines—whether they are on the same server rack, a different rack or even in a different data center—so the network can be available instantly, regardless of where an application is running. Availability is planned for mid-2013.
