A dynamic synchronous transfer mode network includes first and second unidirectional buses 2 and 4, and a plurality of nodes, 0 to N−1. Each node includes a mechanism for selecting a bus. When a first node wishes to initiate a call with a second node, the selected bus is used to communicate with the second node. Each node includes a processor for calculating, for the selected bus, a ratio based on the number of previous reservations made by the node and the number of previous reservations relating to calls to or from the node. If the ratio is below a threshold, then a channel reservation device reserves one or more channels for a call. If the ratio is above the threshold, then the device requests a second node to reserve one or more channels for the call. This overcomes unfair operation of the network caused by the dual-bus topology.
A method of operation of a dynamic synchronous transfer mode network comprising a plurality of buses, wherein, when a first node wishes to initiate a call with a second node:
A node for use in a dynamic synchronous transfer mode network, wherein the node comprises:
A dynamic synchronous transfer mode network, comprising a plurality of nodes and a plurality of buses joining the nodes, wherein each node comprises:
