The GMPLS/OBS Control Plane is a bold research topic. Optical Burst Switching (OBS) networks need to be capable to be rapidly reconfigured with the aim of achieving an efficient use of bandwidth, low latency and high degree of transparency. The OBS Control Plane is just a packet switched network requiring a high control complexity. The demands are clear but a well-defined control plane is still an...
This paper primes a control channel management method for GMPLS-based optical transport networks. The proposed mechanism bundles multiple control channels between adjacent nodes into a single ldquologicalrdquo control channel to hide control channel failure from the control plane signaling and routing protocols such as RSVP TE and OSPF-TE The proposed method is based on three ideas: multiple redundant...
Dynamic protection mechanism was proposed to provision each individual LSP in a group LSP with differentiated survivability. A resilient multi-QoS burst streams transmission over the group LSP was demonstrated in a GMPLS-controlled transparent optical network.
