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 …

A design technique for reliable optical transport networks is presented. The network is first
dimensioned in order to carry a given set of static protected optical connections, each one …

This chapter discusses the changes in technology option or design to support the elastic
concept in an optical network. Next, it introduces in detail some practical aspects of the …

Efficient planning and optimization of wavelength division multiplexing networks is an
important issue today. Integer linear programming (ILP) is the most used exact method to …

How well can telecommunications networks be designed to withstand deliberate attacks by
intelligent agents? This chapter reviews methods for designing communications networks …

Many researches have been investigated on planning and/or designing WDM networks, but
most of them assume that the future traffic demand is known beforehand. However, it is …

Feature Issue on High Availability in Optical Networks The core idea of availability-based
routing consists of exploiting the availability as a link-state metric: this kind of approach has …

This paper investigates a generalized protection framework for availability-guaranteed
connection provisioning in an optical wavelength-division-multiplexed (WDM) network …

Path protection requires finding a working path and a protection path that are link disjoint. In
this paper, we consider two fundamental problems on dynamic lightpath protection in WDM …

The paper proposes five novel protection strategies against single link failure in multicast
multi-fiber WDM networks. These strategies are able to provide rapid recovery from failure …
