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 …

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 …

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 …

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 …

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 …

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 …

Elastic optical networks (EONs) have been receiving extensive attention because of their
inherent flexibility and the efficiency with which they allocate fiber-bandwidth. For an EON …

This article proposes a service level agreement applied to the optical domain (O-SLA),
which is expected to be the near-and long-term network technology of the great bandwidth …

The paper presents a tutorial on multilayer recovery methods. Emphasis is laid not on their
procedural operation, but rather on their quality assessment and differentiation based on …

It took roughly 10 years for the transport network industry to migrate from PDH to SONET. As
this technology swap comes to an end, WDM technology is dawning, promising to …
