| Abstract(in English) | PCE and VNTM are the standard architecture that fully utilizes the MPLS and GMPLS technology. The IP-optical TE server which we have developed based on these architectures constructs multiple virtual networks that consist of IP links formed by optical paths connected between the pairs of IP routers. Network resources used to setup the optical paths are separated and allocated to each virtual network. Since the resource is isolated at the optical level, virtual networks do not affect each other by violation such as excessive use or bursty traffic. Virtual network itself can also be optimized since those are composed of optical paths that are easily set up and torn down dynamically. Topology optimization is done in response to the change of the traffic matrix. Here we introduce about the wide-area experiment of network virtualization, application triggered on-demand path setup, and dynamic reconfiguration of the topology that we done using national testbeds and international connections. The experiments included oversea live streaming of uncompressed HDTV video from a broadcasting studio, and dynamic route change of a MPLS LSP which was carrying live video stream that was being broadcasted on-air in a real television channel. |
