Abstract

We consider the problem of how to balance and/or guarantee bandwidth for queued arbitrated services within the framework of the Medium Access Control layer of the Distributed Queue Dual Bus (DQDB) MAN. The proposed method, which is based on CYclic REquest Control (CYREC) can provide fair sharing and/or guarantee bandwidth. The proposed scheme is based on assigning capacity to each station by setting a quota representing the number of request bits which can be queued for transmission per cycle by that station. Either at the end of a preassigned cycle period or when the Head Of Bus detects that all stations are either idle or have exhausted their quota, a reset bit is used to start a new cycle, during which stations may queue to send another quota of requests. In this way capacity is efficiently guaranteed, as allocations not used by temporarily idle stations may be available to others. Simulation results are presented to demonstrate the improvement in DQDB performance achieved by using CYREC.
