Improving performance for optical TDMA LANs/MANs with traffic control

In order to urge an optical TDMA network to be recommended as a LAN/MAN protocol, traffic-control approaches capable of improving performance on optical TDMA networks must be developed. This paper explores how to apply the unused bandwidth to enhance the performance of a middle-load TDMA network. The tight and loose traffic-control approaches are used to explore how to improve performance. The loose traffic-control approach (the LTC) permits nodes to access bandwidth which is larger than nodal traffic. The difference between the accessible bandwidth and nodal traffic is called the added bandwidth of nodes. The transmissible traffic of nodes with the tight traffic-control approach (the TTC) is equal to nodal traffic. The average waiting time of TDMA nodes (the waiting mean) is analyzed to obtain the upper and lower bounds of the LTC waiting means. Both bounds and the simulate LTC waiting means will be contrasted to explore the effect of added bandwidth.
