Rule-based call-by-call source routing for integrated communication networks

Abstract

Routing subject to multiple quality-of-service (QOS) constraints is considered. Such a problem arises in both private corporate backbone networks and public switched networks, and will become even more prevalent in the future with the emergence of asynchronous transfer mode (ATM) networks. A rule-based call-by-call source routing strategy that makes use of routing fallbacks to accommodate users with diverse QOS requirements is proposed.<>
