Dynamic multilayer routing schemes in GMPLS-based IP+optical networks
TL;DR: Two dynamic multilayer routing policies implemented in the photonic MPLS router developed by NTT for IP+optical generalized MPLS networks are presented and it is observed that p is the key factor in choosing the most appropriate routing policy.
Patent
Optical network, optical cross-connect apparatus, photonic-IP network and node
TL;DR: In this paper, the authors proposed a flooding algorithm to share the link utilization among the remaining nodes in an optical network by calculating the link utilisation observed by the link observation section and by each remaining node.
Patent
Layered network node, network incorporating the same, node, and layered network
TL;DR: In this paper, a layered network node of which a network it belongs is divided up into cells which are constituted by a plurality of nodes; the cells are defined as virtual nodes.
