Abstract
A method and apparatus for load sharing and increasing fault tolerance at a head-end of an interactive information distribution system during a subscriber's video session. A primary head-end controller processes video session data to manage the distribution of streamed video information to a subscriber. In the event of a failure at the primary head-end controller, a secondary head-end controller continues to process session-state data, with minimal interruption to the subscriber's video session.
