Abstract

A method and apparatus for sending delay sensitive information assisted by packet switched networks for network nodes in a computer network. Delay sensitive information such as voice information is sent over higher cost delay sensitive connections. Control and status information for the delay sensitive connections is sent in control messages over lower cost packet switched connections to the nodes in the computer network. Information in the control messages is stored in status tables on the network nodes. The status table is used by network nodes to determine the status of any delay sensitive connections in the computer network and is used to establish a lowest cost connection path or a desired quality of service connection path when a delay sensitive connection between network nodes is requested. Sending delay sensitive control and status information over the lower cost packet switch connections to the network nodes and using status tables on the network nodes to establish delay sensitive connections significantly decreases the costs associated with using delay sensitive connections.
