Abstract

The 802.6 protocol of DQDB MANs aims to maintain a distributed queue for network access and yet inherits access unfairness. In this paper, the DANT protocol is proposed to provide head-end nodes as well as each active node in a DQDB network with real time information about the active node population, the intermodal distance, the position of each node along what bus and the length of a node's downstream bus segment. DANT's current implementation introduces an overhead of 5 bits per slot but alternative implementations which retain the current slot structure of 802.6 and implement the DANT protocol through the use of periodically issued control slots are possible. Results presented in {3,4,5} show that DANT holds much promise for its use in the context of new load balancing and access protection schemes for DQDB MANs.
