Fault Localization at the WDM Layer

Jean-Yves Le Boudec, Patrick Thiran, Carmen Mas

We propose an Alarm Filtering Algorithm (AFA) for the fault management of an optical network that supports multiple failures and works in the presence of passive elements, that is, network elements which may fail but never generate an alarm (e.g. optical f ...

Voice Service Interworking for PSTN and IP Networks

Jean-Pierre Hubaux

n recent years, the Internet has proven its ability to carry real-time data, including voice. Today, a small amount of voice traffic has already been diverted from the Public Switched Telephone Network (PSTN) to the Internet. If it expands, this phenomenon ...

New optical star LAN demonstrator based on FDM with an adapted multichannel Ethernet protocol

Philippe Robert, Daniel Rodellar Gomez, Caroline Brisson

This paper presents a new physical layer demonstrator for Optical Local Area Network. It offers a large total capacity to a large number of connected nodes without requiring optical amplifiers and achieves high modularity and scalability. A new multichanne ...

Designing new network adaptation and ATM adaptation layers for interactive multimedia applications

Multimedia services, audiovisual applications composed of a combination of discrete and continuous data streams, will be a major part of the traffic flowing in the next generation of high speed networks. The cornerstones for multimedia are Asynchronous Tra ...

Fault Localisation for optical networks

Jean-Yves Le Boudec, Carmen Mas

A single failure in a communication network may trigger many alarms. When the communication network uses optical fibres as a transmission medium and increases its capacity by using Wavelength Division Multiplexing (WDM) and Space Division Multiplexing (SDM ...

An Alarm Filtering Algorithm For Optical Communication Networks

Jean-Yves Le Boudec, Carmen Mas

A single failure in a communication network can trigger many alarms. We propose an alarm filtering algorithm for the management of an optical network using Wavelength Division Multiplexing (WDM). The algorithm supports: (i) multiple failures and (ii) passi ...

Design Protection for WDM Optical Networks

Jean-Yves Le Boudec, Olivier Crochat

With WDM networks, the failure of a single link or component may cause the simultaneous failure of several optical channels, potentially making impossible the restoration by rerouting in higher layers directly using the optical network (SDH, ATM, IP). To a ...

Object-oriented method and architecture for virtual private network service management

One of the major trends in the evolution of current corporate networking is an increasing need for high performance long distance communications. Provided as an alternative to leased lines networks, virtual private networks (VPNs) are gaining increasing ac ...
