Abstract
A system which provides session oriented communications between a settop terminal and a headend of a CATV communication system assigns downstream and upstream communication paths to the communication. A data router monitors the downstream communication path and re-routes the downstream communication path when a channel change is requested by a subscriber. The settop terminal notifies the data router that a channel change has been requested by the subscriber. The router re-routes the downstream portion of the data communication to the new channel requested by the subscriber, thereby insuring an uninterrupted data communication session.
