Abstract
This invention describes a method for controlling the creation of data paths of predefined capacity that is needed for timely forwarding of packets in networks where the switches maintain a common time reference. The invention describes a signaling controller that is responsive to a setup request by computing a route of switches for data transmission, and a transmission schedule, which consists of predetermined time frames in which the switches along the route may forward packets of said setup request. The invention describes a switch signaling controller, which operates in every switch and which sends and is responsive to messages regarding reserving and releasing bandwidth on the switch's ports. The invention describes a protocol by which end-stations, gateways, signaling controller, and switch signaling controllers communicate to establish paths of specified capacities; and algorithms for processing signaling messages and finding transmission schedule in the network.
