TL;DR: The proposed bandwidth squeezed restoration scheme takes advantage of elastic bandwidth variation in the optical paths of SLICE to enable spectrally efficient and highly survivable network recovery for best-effort traffic as well as bandwidth guaranteed traffic, while satisfying the service level specifications required from the client layer networks.

TL;DR: 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.

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.

TL;DR: The network resource management system virtualizes and schedules network resources to inter-work with Grid resource scheduler through Web-services interface.

TL;DR: In this paper, a noise figure of 1.8 dB with a 16 dB signal gain was measured by a precisely calibrated electrical spectrum analyser, which is less than the standard quantum limit of 3 dB.
