- BusinessIEEE Communications Magazine
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.
A disjoint path selection scheme with shared risk link groups in GMPLS networks
This letter proposes a disjoint path selection scheme for generalized multi-protocol label switching (GMPLS) networks with shared risk link group (SRLG) constraints. It is called the weighted-SRLG…
GMPLS-based photonic multilayer router (Hikari router) architecture: an overview of traffic engineering and signaling technology
A heuristics-based multilayer topology design scheme that uses IP traffic measurements in a generalized multi-protocol label switch (GMPLS) that yields the optical label switch path (OLSP) network topology, that is, OLSP placement, that minimizes network cost in response to fluctuations in IP traffic demand.
