This paper looks at several aspects of optical layer protection techniques from an
implementation perspective. We discuss the factors that affect the complexity of optical …

Conventional optical networks are based on SONET rings, but since rings are known to use
bandwidth inefficiently, there has been much research into shared mesh protection, which …

This article provides a perspective on optical layer protection and restoration based on the
services offered by carriers using the optical layer. This is different from other viewpoints that …

We are witnessing the evolution of optical networks toward highly heterogeneous, flexible
networks with a widening area of application. As the bandwidth and reliability performance …

In this paper we discuss a quantitative framework for best-effort protection of the optical
layer. This framework provides a way to bridge the gap between two known protection …

Previous advances in WDM technology are now beginning to shift the focus more toward
optical networking and network-level issues. Providing survivability at the optical layer is …

Network Recovery is the first book to provide detailed information on protecting and
restoring communication networks, and it sets a sky-high standard for any that may follow …

A pan-European carriers' carrier network, like other carrier networks, must cope with the
enormous traffic inflation by introducing appropriate network solutions. WDM technology is …

This paper is an introduction to survivability of WDM networks. All the main optical protection
techniques proposed as far as now for the WDM layer are classified and reviewed. In …

Summary form only given. Experimentation with optical switching technology by various
telecom companies for healing an optical network in the face of equipment and fiber failures …
