A switching fabric has input ports, output ports, buffers and at least one switch processor, which determines the available capacity of links at a switch and communicates this information to other switches in a network on a periodic basis. Based on this knowledge, the switch processor of the present invention determines if the necessary number of contiguous time slots in a time frame are available for the call in question. The routing method of the present method uses the periodically updated bandwidth usage to determine a route from a source switch to a destination switch. By utilizing periodic updates of bandwidth usage and assigning contiguous time slots, time slot availability becomes predictable and cell streams travel jointly along the same route, which in turn eliminates cell loss and jitter.
