Abstract
A method and apparatus for pre-establishing and managing Switched Virtual Circuits (SVCs) and Switch Cross-Connects (XCs) to support rapid setup of real-time services in Asynchronous Transfer Mode (ATM) networks are described. SVCs and XCs are pre-established and cached in accordance with communications application-specific rules and maintenance algorithms for each destination and service characteristics in the backbone network. The intelligent management of cached SVCs and XCs permits the backbone network to meet the tight delay budget of delay-sensitive communication applications. With proper management of cached resources, connection setup can be rapidly effected even during periods of high demand. The advantage is a connection setup mechanism having adequate granularity to ensure both efficient network usage and rapid response to service requests.
