Abstract

A method implemented by a network element functioning as a home agent (HA) for a mobile node (MN) communicating with a corresponding node (CN) using Mobile Internet Protocol version 6 (MIPv6), the method including selecting by the HA a virtual home agent (VHA) in the network to provide home agent services to the MN with a better quality of service than the HA, sending a flow switch request (FSR) message to the selected VHA, the FSR message including a home keygen token, an address of the CN and a care-of address of the MN, the FSR message to cause the selected VHA to direct the CN to send data traffic for the MN to the selected VHA instead of the HA, and receiving a flow switch acknowledgement (FSA) message from the VHA indicating that the selected VHA has successfully redirected the data traffic from the CN to the MN.

Description

technical field [0001] This application claims priority from U.S. Provisional Patent Application 61 / 366,314, filed July 21, 2010, and is also filed on the same date as this application and is commonly owned, entitled "SYSTEM AND METHOD FOR MOBILITY WITH A SPLIT HOME AGENT ARCHITECTURE USING MPTCP "Cross-referenced to the co-pending application. The cross-referenced applications are incorporated herein by reference. Background technique [0002] Mobile Internet Protocol version 6 (MIPv6) allows a mobile device to maintain a persistent connection with another device that supports Mobile Internet Protocol version 6. Two independent communication modes are supported using MIPv6: bi-directional tunneling (BT) mode and route optimization (RO) mode. When the mobile node does not exist in the home network, Mobile IPv6 utilizes the home agent node to manage the forwarding of the data traffic to the mobile node. [0003] When the mobile node moves to a foreign network, the mobile n...
