The current trend is to integrate a constantly increasing number of services in the same
communication network. Some services have very high resilience requirements, while other …

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 …

In an optical WDM mesh network, different protection schemes (such as dedicated or shared
protection) can be used to improve the service availability against network failures …

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 …

Coping with network failures has been recognized as an issue of major importance in terms
of social security, stability, and prosperity. It has become clear that current networking …

To proactively defend against intruders from readily jeopardizing single-path data sessions,
we propose a distributed secure multipath solution to route data across multiple paths so …

This paper presents a recovery time analysis of differentiated resilience concepts in MPLS
networks. In analogy to the differentiated services QoS model a differentiated resilience …

Coping with network failures has become a major networking challenge. The concept of
tunable survivability provides a quantitative measure for specifying any desired level (0 …

Current survivability schemes typically offer two degrees of protection, namely full protection
(from a single failure) or no protection at all. Full protection translates into rigid design …

This thesis investigates the provisioning of resilience against network failures in multilayer IP-
based optical networks. To investigate and evaluate existing and novel resilience strategies …
