Abstract
Virtual circuits are dynamically established in a telecommunications network. A cache duration is adaptively determined based on at least one characteristic of the telecommunications network. A virtual circuit is established for a connection between a source and a destination. The virtual circuit is cached when the connection between the source and the destination terminates. The cached virtual circuit is reused when a new connection request occurs during the cache duration. The cached virtual circuit is released after the cache duration when no new connection request occurs during the cache duration.
