Summary T-SDN Platfrom extends former SDN from enterprise networks to carrier networks, providing the decision mechanism of how to engineer their IP/MPLS(-TP) packet networks (layer 2/layer 3) and optical transport networks (layer 0/layer 1) organically in multi-vendor or multi-domain networks. The future network should accommodate 4 requirements : SUPER connectivity, Software -based flexibility, operational Intelligence, and new User Experience.
