Network resource reservation control method and apparatus, receiving terminal, sending terminal, and relay apparatus

摘要

Resources such as VCs (Virtual Connections) are efficiently reserved. When an ASP (AMInet Setup Protocol) message is sent from a receiving terminal (RECEIVER) to a sending terminal (SENDER), virtual connections of a predetermined bandwidth individually specified by the ASP message are established in the direction from the receiving terminal to the sending terminal and in the direction from the sending terminal to the receiving terminal independently at an edge router, backbone routers, and an edge router in this order through which the ASP message passes.
