Abstract

The sojourn time of the prioritised DQDB MAN with bursty traffic input is studied. The expression of the mean sojourn time of the message transmitted at the higher priority level is given. After an investigation of the transient behaviour of a related random walk process, the sojourn time of the packet at the lower priority level is derived. The authors obtain the expression for the mean sojourn time of the message with the lower transmission priority. The conclusions drawn are that the mean sojourn time of the message at either higher or lower priority, is approximately a linear function of the mean message length, and a marked performance improvement is obtained by adopting the higher priority level for the user, especially when the lower-priority traffic load from the downstream users is heavy
