Distributed restoration in an ATM test bed network

Network resilience is a crucial area of concern for telecommunications network operators who aim to provide high availability services supported by a broadband platform based on ATM technology. This paper describes the development of an ATM rest bed network which incorporates resilience by executing distributed restoration in the event of failures. Since the work originated from collaborative research between BT Laboratories and Alcatel Telecom of Belgium, the paper highlights challenges faced in developing a restorable network, both by a network operator, and a switch manufacturer.
