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 ...

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 ...

Muteness Failure Detectors, Specification and Implementation

Rachid Guerraoui, André Schiper

This paper extends the failures detector approach from crash-stop failures to muteness failures. Muteness failures are malicious failures in which a process stops sending algorithm messages, but might continue to send other messages, e.g. 'I-am-alive' mess ...

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 ...
