RESOURCE RESERVATION PROTOCOL SUPPORTING SYSTEM AND METHOD IN INTEGRATED IPV4/IPV6 NETWORK

摘要

An RSVP(Resource Reservation Protocol) supporting method in an IPv4(Internet Protocol version 4)/IPv6 unified network system and a system therefor are provided to enable traffic transmitted to a dual stack host located within an IPv6 network to receive QoS(Quality of Service) from a server, thereby ensuring QoS by setup through end-to-end RSVP connection. A dual stack host(100) within an IPv6 network transmits an end-to-end QoS session connection request message to an IPv4 server(500) through a DSTM(Dual Stack Transition Mechanism) TEP(Tunnel End Point)(300)(S10-S60). The server(500) transmits an end-to-end path message to the host(100) through the TEP(300)(S70,S80). The TEP(300) transmits a path message for resource reservation to the host(100)(S90). The host(100) sends an end-to-end resource reservation request message to the server(500), so that resource reservation is set within an IPv4 network(S100,S110). The host(100) sends a resource reservation request message to the TEP(300), so that resource reservation can be set within an IPv6 network(S120).
