EFFECTIVE MULTIPRIORITY SCHEME FOR DQDB MAC PROTOCOL

The authors propose a modification to the priority scheme specified in the DQDB standard enabling it to operate effectively on large high-sp eed networks requiring the use of the BWB mechanism to achieve fairnes s. The modified priority scheme is also capable of operating with the BWB mechanism disabled and is therefore general in its application. Re sults of a simulation analysis ore presented demonstrating the effecti veness of the modified priority scheme for a number of different scena rios.
