Abstract

Due to the traditional realization of distributed-queue dual-bus (DQDB) networks, optical networks with time-division multiple access (TDMA) have the unfair-access problem. It prevents users from adopting the optical TDMA networks. In order to promote bandwidth utility and lower constructional cost of communication networks, this paper discusses the property of the waiting time on optical TDMA networks to distinguish whether the unfair-access problem can be completely solved or not. After the analysis of the waiting time on optical TDMA networks, it is exhibited that the average waiting time of nodes is in inverse proportion to nodal traffic regardless of network topology. Based on this property, it can be inferred that an optical TDMA network will have ideal fair behavior if its access protocol performs traffic control. Referring to the property of the waiting time, the optical TDMA network can be taken as a subnetwork of the public. Otherwise, the unfair-access problem should be solved completely.
