Self Organized Terminode Routing

Jean-Yves Le Boudec, Ljubica Blazevic

We consider the problem of routing in a wide area mobile ad-hoc network called Terminode Network. Routing in this network is designed with the following objectives. First, it should scale well in terms of the number of nodes and geographical coverage ...

A Protection-based Approach to QoS in Packet over Fiber Networks

Patrick Thiran

We propose a novel approach to Quality of Service, intended for IP over SONET (or IP over WDM) networks, that offers end-users the choice between two service classes defined according to their level of transmission protection. The first service class (call ...

Protection Interoperability for WDM Optical Networks

Jean-Yves Le Boudec, Olivier Crochat

The failure of a single optical link or node in a Wavelength Division Multiplexing (WDM) network may cause the simultaneous failure of several optical channels. In some cases, this simultaneity may make it impossible for the higher level (SONET or IP) to r ...

Fault Localization at the WDM layer

Jean-Yves Le Boudec, Patrick Thiran, Carmen Mas

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

Chirped fiber Bragg gratings for WDM chromatic dispersion compensation in multispan 10-Gb/s transmission

We report here the fabrication of fiber chromatic dispersion compensators, along with the tests of those components in wavelength-division-multiplexed transmission at 10 Gb/s and an analysis of their performance by simulation. ...

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 ...

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 ...

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 ...
