Self-healing rings in a synchronous environment

Abstract
An overview of different self-healing network architectures, focusing on ring architectures, is presented. Digital cross-connect systems-based self-healing and diversely routed protection are briefly discussed. Since a typical self-healing network design may use all of the self-healing architectures, a discussion on applications perspectives, illustrating how the various self-healing technologies may best fit in the evolving network, is included.
