Juniper Networks together with NTT Communications successfully demonstrated Generalized Multiprotocol Label Switching (GMPLS) signaling to dynamically establish a OC-768/STM-256 Layer 1 network path between NTT Communications’ Makuhari and Othemachi Points of Presence (PoPs). The tests used Juniper’s T640 core routers.
GMPLS extends the efficient label switching mechanism of MPLS to the physical network layer, providing a control plane that allows networks to take advantage of an advanced infrastructure, including high-speed links such as OC768c, which is fastest optical link available today. Using GMPLS, routers can intelligently signal the optical layer, enabling providers to establish, change or tear down optical links in real time.
Juniper said its T640 platform was the only router in the trial that could perform the high speed connection via a logical router exchanging the IPv4 and IPv6 traffic with a master physical router controlling a Layer 1 path with GMPLS signaling. http://www.juniper.net
