Abstract:
A method of reserving network resources for a transmission, the method comprising:at an access node in the network, receiving resource reservation requests from sending network users connected thereto, each resource reservation request specifying an intended destination and a bandwidth requirement; in response to each received resource reservation request, performing an admission control procedure; in the event that the resource reservation request passes admission control, transmitting a request across the network to the intended destination associated therewith to allow other nodes to perform admission control procedures; in the event that the resource reservation request passes all admission control procedures to the intended destination, sending from the access node to the sending network user associated therewith a ticket message containing all necessary connection information; and allowing access to the network for a transmission from the sending network user when the transmission includes the ticket message, wherein the admission control procedure at the access node determines whether the required resource is available during a time slot by: determining what resources have already been allocated during said time slot, and what resources have already been reserved or requested, wherein sending a ticket from the access node to the sending network user during a time slot allocates the required resources for said time slot, and reserves the required resources for a second time slot immediately following said time slot.
