NTT is showcasing its Versatile Openflow vaLidaTor (VOLT) resource control system for software defined networking (SDN) at this week's Interop Tokyo 2013.
NTT said VOLT, which was developed in partnership with Fujitsu, is able to duplicate the entire route information and configuration of OpenFlow. This can be used to test a new network under the same conditions as the real environment.
The system consists of an MPLS edge router and controller.
