Bandwidth management for ATM-based LANs

In this paper the bandwidth assignment criteria, well suited in ATM LANs environments, have been extensively examined. In particular. After a discussion of the various schemes, we analyzed the bandwidth advertising criterion both by analytical methods and simulation. The cell loss and packet loss probability have been evaluated as a function of the usual network parameters (number of users, packet length, burstiness, etc.), pointing out that the gain factor of the network (i.e., the number of multiplexed sources given the quality of service) is directly proportional to the source burstiness. This intuitive result can be efficiently exploited in ATM LAN environments, where, it is supposed that a significative portion of traffic comes from bursty users. >
