Abstract

An asymmetric communication protocol providing semi-reliable transmission with improved availability. Messages are provided to a scheduling sender which repeatedly rebroadcasts the data for a specified time period. Multiple messages are arranged in a data carousel with each message transmitted on each revolution of the carousel. Messages are removed as they become obsolete. Clients joining the broadcast late continue to have access to data on the carousel.
