Abstract:
A network system comprising;terminals and relaying nodes each having a reservation message processing unit for transferring a packet wherein; the reservation message processing unit of a packet receiving terminal transmits to a packet transmitting terminal a request message in which a reservation request condition is stored in order to request a resource reservation for the packet; the reservation message processing unit of the packet transmitting terminal having received the request message transmits to the relaying nodes on the same route as the packet an acknowledgement message in which the reservation request condition is stored responsive to the request message; the reservation message processing unit of each relaying node provides a resource reservation for the relaying node itself according to the reservation request condition in the acknowledgement message instead of the request message and transfers the acknowledgement message to the same route as the packet; and after the acknowledgement message has passed through all the relaying nodes which relay the packet and then the reservation message processing unit of the packet receiving terminal has received the acknowledgement message, a network resource reservation procedure is completed.
