<p><b>Abstract</b>—Several medium access control (MAC) schemes have been developed for dual-bus networks such as DQDB [<ref type="bib" rid="bibT11108">8</ref>], Fasnet [<ref type="bib" rid="bibT111010">10</ref>], CRMA [<ref type="bib" rid="bibT111012">12</ref>], and <it>Simple</it> [<ref type="bib" rid="bibT11109">9</ref>]. However, how to guarantee the timely delivery of <it>isochronous</it> (real-time) messages with hard deadline constraints is one of the open issues yet to be solved. In [<ref type="bib" rid="bibT11105">5</ref>], 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 [<ref type="bib" rid="bibT11105">5</ref>] 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.</p>
