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 …

Современные телекоммуникационные сети являются мультисервисными. При этом
разные услуги нуждаются в обеспечении различных показателей надежности. Попытка …

The Internet revolution. Once, the public was delighted with 14.4 modem access and
fascinated by low-tech Web site content. But not for long. Technology has raced to keep up …

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 …

The authors (Fumagalli and Tacca (2001)) introduced the concept of differentiated reliability
(DiR) applied to dedicated path protection (DPP) switching in wavelength division …

In hybrid vehicular ad hoc networks (VANETs), roadside units (RSUs) are more powerful
and robust than onboard units (OBUs) equipped on vehicles, which can exchange …

This paper presents both theoretical and experimental studies carried on wavelength-
division multiplexing (WDM) networks with arbitrary (mesh) topology that provide optical …

Optical networks based on WDM technology have become a promising solution to realize
transport networks that can meet the ever-increasing demand for bandwidth. As WDM …
