Abstract

See full text

A method for managing MAC messages is provided which supports dynamic resource reservation for upstream data traffic in a broadband cable system. Three specialized MAC management messages of Dynamic Session Addition, Dynamic Session Deletion, and Dynamic Session Acknowledgment are used to control setting of a filter spec parameter in a cable modem. The present invention provides upstream bandwidth resource reservation which allows packet scheduling to occur at a CMTS, and packet classification to occur at a cable modem. Such an arrangement allows the RSVP protocol to be adapted for use at the OSI protocol layer of a typical cable modem, thereby improving efficiency of network bandwidth/resource allocation.
