Abstract
A technique is described for improving packet performance in an access network. The access network comprises a Head End and a plurality of nodes. The access network further includes at least one shared-access upstream channel used by the first plurality of nodes to communicate with the Head End. Propagation delay data associated with at least a portion of the plurality of nodes using the at least one upstream channel is obtained. The propagation delay data is then used to dynamically adjust the lookahead time value associated with the generating of MAP messages for the at least one upstream channel.
