System and method for delivering data streams of multiple data types at diffferent priority levels

摘要

A Server (100) provides a data stream of data of a primary type and one or more secondary types and transmits the primary type data at a first designation and the data of the one or more secondary types at one or more other designations. A Router (600) routes data of the first designation through a Network (500) at a first priority and routes data of the one or more other designations through Network (500) at one or more priorities lower than the first priority such that, when congestion in Network (500) requires that data be discarded, Router (600) discards data of the one or more other designations before discarding data of the first designation. A Client (200) receives data of the first and of the one or more designations through Network (500) and combines the data to provide a representation of the data stream transmitted from Server (100).
