Title: Fast End-to-End Restoration Mechanism with SRLG using Centralized Control
State: Active
Authors: Jun Choi
Group: Individual Submissions (none)
Date: 2004-10-29
This draft describes the concept of the Shared Link Risk Group (SRLG) based
logical ring configuration and recovery method using ring SRLG for the
purpose of PCE-based backup path computation. In this restoration
architecture, backup paths can be easily established through the end-to-end
path which follows from the logical ring configuration. It guarantees the
establishment of backup path disjoint from the working path at all levels.
To take advantage of bandwidth considerations and fast restoration
mechanisms, a centralized Controller is used to provide dedicated
protection to Optical Transport Networks using the SRLG concept.
