Abstract

A computer system comprising one or more information source modules and information display modules interconnected by a communications link. The information source module transmits, and the information display module receives, original information items using a peer-to-peer message transmission protocol. Thereafter, the information source module transmits update information items to the information display modules at one time using a multi-cast information transmission mechanism. In the multi-cast information transmission mechanism, an information display module determines when it has missed an update information message, waits a selected backoff delay time, and transmits a retransmission request for update information messages whose retransmission has not been requested by other information display modules during the backoff delay period. The information display modules receive the retransmitted update information messages and process them in the same order in which the corresponding update information messages were originally transmitted. The original update information messages and the retransmitted update information messages are transmitted over different channels and only those information display modules that need to receive the retransmitted messages monitor the retransmission channel.
