Lightpath Provisioning in IP-centric MPλS Optical Networks

Multi Protocol Lambda Switching (MPλS)

Luc Ceuppens Calient Networks Abstract Realizing the important role that photonic switches can play in data-centric networks, a number of leading router and optical equipment vendors are collaborating to combine the control plane of MPLS with the point-and-click provisioning capabilities of photonic switches. This document describes how MPλS (Multi Protocol Lambda Switching) will enable the ser...

Survivability of IP over WDM Background on Network Survivability

In this article we investigate the problem of restoration scheme for IP over WDM networks. Network reliability gains importance with the huge volume of traffic carried by such networks. Providing survivability at the optical layer is inherently attractive, but raises many questions and challenges, given the characteristic of optical aggregated lightpath and relatively coarse traffic granularity...

A Di erentiated Optical Services Model for WDM Networks

This article addresses the issues of scalable end-to-end QoS in Metropolitan DWDM networks serving as transit networks for IP access networks. DWDM o ering few wavelengths have in the past been deployed in backbone networks to upgrade point-to-point transmission where sharing is based on coarse granularity. This type of DWDM backbone networks o ering few lightpaths, provides no support for QoS ...

Resilience Provisioning Mechanisms for IP-Centric Optical Networks

IP-Centric Control and Management of Optical Transport Networks

Previous techniques for the management and control of optical transport networks are proving inadequate in today’s rapidly evolving multivendor environments. This article examines the issues and challenges involved in developing a standardized optical network control plane. The control of optical transport networks is decomposed into provisioning models, a circuit provisioning process based on ...
