<p>A method and a system for managing available bandwidth-guaranteed high-speed parallel mobility with multiple identical interfaces in a wireless LAN/MAN(Local Area Network/Metro area Network) are provided to apply intelligent mobility detection, parallel packet processing, and a spider handover technique to a mobile node, thereby dynamically providing an available bandwidth as much as necessary for the QOS(Quality of Service) request of a user and preventing handover time delay or packet loss according to movement between cells. A method for managing available bandwidth-guaranteed high-speed parallel mobility comprises the following steps of: selecting the AR(Access Router) of a main AP(Access Point) connected to a mobile node as a C-DAR(Current Distribution Access Router) by using mobility detection information from a second layer according to the movement of the mobile node; and connecting plural ARs having the possibility of handover by using the COA of MIPv4(Mobile Internet Protocol version4) or MIPv6, forming plural hierarchical bi-directional tunnels for parallel packet transmission between the mobile node and the C-DAR through the connected ARs and transmitting packets, and transmitting the packets to the C-DAR and between a home agent and a target node.</p> |
