Abstract :
Several medium access control (MAC) schemes have been developed for dual-bus networks such as DQDB, Fasnet, CRMA, and Simple. However, how to guarantee the timely delivery of isochronous (real-time) messages with hard deadline constraints is one of the open issues yet to be solved. In Han, Hou and Shin (1997), we laid a formal basis for allocating prearbitrated slots to isochronous message streams in dual-bus networks and devised a slot allocation scheme to statically establish a set of isochronous message streams at system initialization. In this paper, we complement our work in Han, Hou and Shin (1997) and propose, with the necessary theoretical base established, a dynamic message stream setup and tear-down scheme for dual-bus networks. The resulting channel establishment and termination procedures are simple and can be easily implemented in dual-bus networks
