Working Group : Architecture & Signaling Working Groups Title : Inter - domain routing with Shared Risk Groups

This document discusses how inter-domain routing using Shared Risk Group (SRG) may be used for computing diverse paths, and also discusses the extensions that we propose for routing (and eventually signaling) protocols. The concepts proposed in this document are useful to provide the requested intelligent control plane for multi-layered networks.
