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 ...
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 ...
In this paper, we investigate the applicability of backtrack technique for solving the vertex enumeration problem and the face enumeration problem for a convex polyhedron given by a system of linear inequalities. We show that there is a linear-time backtra ...
An optical network is described that is capable of recognizing at standard video rates the identity of faces for which it has been trained. The faces are presented under a wide variety of conditions to the system, and the classification performance is meas ...

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 ...

The problem of determining whether a graph G contains a threshold subgraph containing at least h edges is shown to be NP-complete if h is part of the input as the problems of minimum threshold completion, weighted 2-threshold partition and weighted 2-thres ...
The safety of utilisation is one of the chief current preoccupations. The user must be able to know what impact the failure of one ore more network elements will have on the continuity of supply, as well as the countermeasures to be taken against degradati ...
