Abstract
Delay-sensitive information (e.g., voice, video) and non-delay-sensitive user data are combined and transmitted over a single UTP cable forming part of a star-connected Ethernet local area network. Master Ethernet packets of fixed length are formatted with fixed length portions assigned to the two types of information and transmitted at a constant fixed rate. The delay sensitive information is extracted, switched and transmitted at a constant bit rate. The non-delay sensitive information is segmented and transmitted asynchronously in a user data portion of the Master Ethernet Packet.
