Waiting time analysis in a single buffer DQDB (802.6) network

The statistics of the request and countdown counters of a user in a network that operates with the DQDB (distributed queue dual bus) media access protocol are investigated. Assuming that a user can have at most one packet waiting for transmission, an expression is obtained for the steady-state generating function of the number of requests queued ahead of an arriving packet. Given this number, the waiting time of the packet can be easily obtained. The results provide an insight on how traffic, generated from the left and the right of a user in the network, affects the waiting time characteristics of packets generated by the user.<
