METHOD FOR CONTROLING PACKET LOSS OF HANDOVER IN INTERNET SERVICE SYSTEM

摘要

A hand-over packet loss control method in an Internet service system is provided to maintain the connection state through a transfer Internet protocol version 6 when changing the data transmission path. At the first point of time(T1), a process for searching continuously the movement toward a new access router(122) is performed. Because the present moving node(110) is not moved to the new access router, an HA(Home Agent)(140) and an opponent node(150) have the address of PCoA and transmit the data packet including a class and a label to an MAP(Mobility Anchor Point)(130). The MAP maintains the information included in the received packet and transmits the received packet to a previous access router(121) corresponding to the class and label on a binding update table. The previous access router transmits the received packet to the moving node. The moving node produces the data packet as a source of PCoA and transmits the produced data packet to the MAP through the previous access router. The transmitted packet includes the address of the opponent node.
