Abstract
The Demand Priority LAN is an upcoming standard of IEEE’s LAN/MAN Standards Committee (still better known as IEEE Project 802) It aims at allowing for a smooth migration from both ISO/IEC 8802-3 and ISO/IEC 8802-5 LANs to a higher speed LAN. Additionally, the new protocol aims at supporting interactive multimedia applications by providing a low latency service for high-priority traffic. This paper is based on Draft 6.0 of the upcoming standard and the results of discussions during the meeting of IEEE 802.12 in Nov. 1994. It starts with a brief description of basic characteristics of the network topology and the medium access control protocol. In the main part, it presents simulation results for normal priority traffic in scenarios with different variable bit rate high priority loads. It addresses important implementation issues and clearly shows the advantages of using service strategies different from those included in the current version of the standard.
