Abstract: This paper suggests a CSMA/CD compatible MAC protocol for real time transmissions in a Home or Small Office Local Area Network. The protocol allows high priority devices transmitting real time traffic such as digital video and audio to communicate with each other, with guaranteed low delay and jitter, across an existing Ethernet, which is also supporting standard Ethernet devices such as PCs, printers and ISDN routers. A device implementing the new MAC can also communicate across the Ethernet with the standard devices.
