Analysis of Capacity Reprovisioning in Optical Mesh Networks

by Chadi Assi, Wei Huo, Abdallah Shami, Nasir Ghani, Senior Member - IEEE Com. Letters , 2005
"... Abstract — We consider optical mesh networks and we study the problem of improving service availability under dual near-simultaneous failures. We propose a re-provisioning algorithm that improves the robustness of optical mesh networks and we compare its performance with another scheme under various ..."

Soliton ultrafast all-optical mesh networks

by A. Bononi, F. Forghieri, P. R. Prucnal - IEE Proc.-J , 1993
"... Abstract: Channel transmission error arguments show how the size of an all-optical multihop network employing deflection routing is limited for a given optical bit rate. These limits are quan-tified for nonregenerative all-optical mesh net-works such as Manhattan Street network and ShumeNet employin ..."

Generalized loop-back recovery in optical mesh networks

by Muriel Médard, Richard A. Barry, Steven G. Finn, Wenbo He, Steven S. Lumetta - IEEE/ACM TRANSACTIONS ON NETWORKING , 2002
"... Current means of providing loop-back recovery, which is widely used in SONET, rely on ring topologies, or on overlaying logical ring topologies upon physical meshes. Loop-back is desirable to provide rapid preplanned recovery of link or node failures in a bandwidth-efficient distributed manner. We i ..."

introduce generalized loop-back, a novel scheme for performing loop-back in optical mesh networks. We present an algorithm to perform recovery for link failure and one to perform generalized loop-back recovery for node failure. We illustrate the operation of both algorithms, prove their validity

Lightpath Routing for Maximum Reliability in Optical Mesh Networks

by Shengli Yuan , Saket Varma , Jason P Jue - Journal of Optical Networking (OSA , 2008
"... We consider the problem of maximizing the reliability of connections in optical mesh networks against simultaneous failures of multiple fiber links that belong to a shared-risk link group (SRLG). We study the single-lightpath, parallel-lightpaths, and lightpath protection problems for connections b ..."

Protecting multicast sessions in WDM optical mesh networks

by Narendra K. Singhal, Biswanath Mukherjee - Journal of Lightwave Technology , 2003
"... Abstract—Recent advances in wavelength-division-multiplexing (WDM) technology are expected to facilitate bandwidth-intensive multicast applications. However, a single fiber (bundle) cut on such a network can disrupt the transmission of information to several destination nodes on a “light tree”-based ..."

(O–E–O) approach and the other using transparent (all-optical) approach. We expand our formulations to accommodate sparse splitting constraints in a network, in which an optical splitter has limited splitting fanout and each node has a limited number of such splitters. We develop a profit

Routing Lightpaths In Optical Mesh Networks With Express Links

by Ramamurthy, Ramu Ramamurthy, Jean-françois Labourdette, Sid Chaudhuri, Raphael Levy, Pambos Charalambous , 2002
"... This paper studies a wavelength-convertible core optical network consisting of backbone nodes with optical switches interconnected by point-topoint WDM fiber links in a mesh interconnection pattern. The optical network supports unprotected and shared-mesh protected lightpath services. Lightpaths ..."

Efficient Channel Reservation for Backup Paths in Optical Mesh Networks

by Somdip Datta, Sudipta Sengupta, Subir Biswas, Samir Datta - in IEEE GLOBECOM 2001 , 2001
"... In an optical mesh network, backup channels are shared between multiple lightpaths to reduce restoration capacity overhead. The sharability of channels is usually constrained by the mandate to provide 100% recovery of all lightpaths affected by any single event failure in the network. This paper pro ..."

Reliability In Single Domain Vs. Multi Domain Optical Mesh Networks

by Ahmet Akyamac, Sudipta Sengupta, Jean-Francois Labourdette, Sid Chaudhuri, Stephen French - in Proc. National Fiber Optic Engineers Conference , 2002
"... on the number of unavailable minutes per year. The widespread belief is that networks with faster restoration times are more reliable, created by the assumption that fast restoration from a failure leads to smaller down time. This is not necessarily the case since it has been shown that reliabilit ..."

that reliability may have little to do with the restoration speed when the restoration time is small compared to the mean time to repair of the failed elements. In this paper, we compare the reliability of optical mesh networks with multi domain restoration and single domain restoration using both dedicated
