Abstract: For a ring communication system, an access mechanism is provided and supported by medium access control means so that different kinds of traffic are optimally accomodated. Signaling information (SG) and isochronous data (IS) keep their position in a synchronous time raster while propagating on the ring, whereas variable-length data frames (DF A, DF B, DF C, DF D) can be relatively shifted in their position during propagation on the ring, to allow for the insertion of additional variable-length data frames (DF E, DF F), thus giving to all stations attached to the ring a fair chance for transmitting such data frames (DF). The data frames are partitioned into slot-size segments, and the mechanism guarantees that the segments of any data frame will not be interrupted by segments of another such data frame.
