Centralized vs Distributed Fault Localization

In this paper we compare the performance of fault localization schemes for communication networks... more In this paper we compare the performance of fault localization schemes for communication networks. Our model assumes a number of management centers, each responsible for a logically autonomous part of the whole telecommunication network. We briefly present three different fault localization schemes: namely, "Centralized", "Decentralized" and "Distributed" fault localization, and, we compare their performance with respect to the computational effort each requires and the accuracy of the solution that each provides. 1 INTRODUCTION Usually, a single fault in a large network results in a number of alarms, and it is not always easy to identify the primary source(s) of failure. The problem of fault management becomes even worse when several faults occur coincidentally in the telecommunication network. The fault management process can be divided into three stages: alarm correlation, fault identification, and testing. The first two stages, usually referred to a...

Virtual trees routing protocol for a wireless ATM LAN

Proceedings of ICUPC - 5th International Conference on Universal Personal Communications, 2000

This paper presents a new routing algorithm for a wireless ATM (asynchronous transfer mode) LAN (... more This paper presents a new routing algorithm for a wireless ATM (asynchronous transfer mode) LAN (local area network). The LAN combines positive aspects of connection-oriented and datagram communications schemes in its usage of the ATM VP/VC (virtual path/virtual channel) concept. In this scheme, a set of VPI (virtual path identifier) trees, rooted at each node in the LAN, are preestablished.

The LB-characterization of the flow changes at the ATM network boundaries since overhead is added/removed and delay is introduced due to the mapping between IP packets and ATM cells.

The authors provide a survey of a large number of published papers in the area of fixed, dynamic, and hybrid allocation schemes and compare their trade-offs in terms of complexity and performance. We also investigate these channel allocation schemes based on other factors such as distributed/centralized control
