ABSTRACT:
In standard token-based LANs (e.g., FDDI, Token Ring) an equal share of the ring bandwidth is made available to each node. Certain nodes (e.g., bridges, routers, servers) require a larger representation (bandwidth) than other nodes. A surrogate (bridge/router) node is presented which achieves this in a standard compliant manner. The bridge/router may serve as a surrogate on each ring representing multiple stations from the other ring. The multiplicity of stations is adjusted either statically or dynamically to provide sufficient added bandwidth to the surrogate to reduce delay and packet loss characteristic of the conventional single station bridge or router. The increased bandwidth utilization and FDDI ring performance resulting from the implementation of this invention is transparent to the individual stations and the ring in a way that is advantageous to both single media and multimedia usages within defined network local and non-local areas.
