The expressions for the mean sojourn time of the message with two transmission priority are obtained. The conclusions drawn from the paper are that, the mean sojourn time of the message, at either higher or lower priority, is a linear function of the mean message length approximately, and the performance improvement by adopting the higher priority level for the user is remarkable, especially when the lower-priority traffic load from the downstream users is heavy.展开更多

The performance of the DQDB MAN for Local Area Networks(LANs) interconnection is analyzed. The effects of message length, traffic load of upstream and downstream nodes and the parameters of bandwidth balancing mechanism and network counters on the sojourn time of message in the buffer are investigated, which present a valuable reference for the implementation of the DQDB MAN.展开更多
