Dynamic WDM Mesh Network Design with Dynamic Optical Path Protection

نویسنده

  • Stefanos T. Mylonakis
چکیده

A WDM mesh network is planned and designed so that to satisfy all its demands. Each connection has to be protected with the a) dedicated way, b) shared way and c) the benefits of the shared way versus the dedicated way are also showed. The shortest path algorithm is used for all dynamical cases. The network uses wavelength conversion. Keywords-dedicated protection, optical channel layer, shared protection, shortest path, WDM mesh networks.

A Dynamic Partitioning Sub-Path Protection Routing Technique in WDM Mesh Networks

With the increasing popularity of bandwidth-intensive applications, network traffic has been growing exponentially. Wavelength Division Multiplexing (WDM) is a technique that can harness the huge bandwidth available in an optical fiber to satisfy the network demand. Due to the multiplicity of the connections on any single link, fault tolerance is of utmost importance in such WDM networks. Activ...

Dynamic Provisioning of Survivable Multicast Sessions in Optical WDM Mesh Networks

We investigate dynamic provisioning of multicast sessions while protecting them against any single fiber cut in optical WDM mesh networks. Our proposed segment-protection and path-pair-protection schemes exhibit very good performance relative to other schemes.

Dynamic lightpath protection in WDM mesh networks under wavelength-continuity and risk-disjoint constraints

Path protection requires finding a working path and a protection path that are link disjoint. In this paper, we consider two fundamental problems on dynamic lightpath protection in WDM mesh networks. In the first problem, we consider a network without wavelength converters; thus both the working lightpath and protection lightpath are subject to the wavelength continuity constraint. Existing pol...

Extension of segment protection for bandwidth efficiency and differentiated quality of protection in optical/MPLS networks

This paper investigates the problem of dynamic survivable lightpath provisioning against single node/link failures in optical mesh networks employing wavelength-division multiplexing (WDM). We unify various forms of segment protection into generalized segment protection (GSP). In GSP, the working path of a lightpath is divided into multiple overlapping working segments, each of which is protect...

Algorithms for Provisioning Survivable Multicast Sessions against Link Failures in Mesh Networks

In this paper, we investigate new algorithms for efficiently establishing a multicast session in a mesh network while protecting the session from a link failure, e.g., a fiber cut in an optical network. First, we study these algorithms for protecting a multicast tree in a mesh network and then extend them for dynamic provisioning of survivable multicast connections where connections come and go...
