Embodiment Construction

[0015] In the following description, numerous specific details are set forth. It is understood, however, that these specific details may not be needed to practice the embodiments of the invention. In other instances, well-known circuits, structures and techniques have not been shown in detail in order not to obscure the understanding of this description. However, it will be appreciated by those skilled in the art that the present invention may be practiced without such specific details. With the included description, one of ordinary skill in the art will be able to implement appropriate functionality without undue experimentation.

[0016] will now refer to figure 1 and 4 - Exemplary embodiment of 6, describing the operation of the flowchart. However, it should be understood that the operations of the flowcharts can be performed in accordance with reference figure 1 and 4 - Other embodiments of the present invention other than the embodiment described in 6 are carried ou...

Abstract

A method implemented in a network element acting as a Home Agent (HA) of a Mobile Node (MN) for communicating with a Correspondent Node (CN) using Mobile Internet Protocol Version 6 (MIPv6), the method comprising by the HA based on a predefined The policy selects a virtual home agent (VHA) to provide the home agent service of better quality of service than the HA to the MN, and sends a flow switching request (FSR) message to the selected VHA, and the FSR message includes a transmission control protocol (TCP) parameter and The FSR message includes the care-of address for the MN and the address of the CN. The FSR message initiates flow redirection at the VHA using a multipath TCP exchange and receives a Flow Switching Acknowledgment (FSA) message from the VHA indicating that the VHA is receiving data from the CN. packet, and tunnel the data packet to the MN at the care-of address.

Description

technical field [0001] This application claims priority to U.S. Provisional Patent Application 61 / 366314, filed Jul. 21, 2010, and is also cross-referenced to commonly-owned U.S. Provisional Patent Application 61 / 366,314, filed on the same date as this application, entitled "SYSTEM AND METHOD FORPROVIDING MOBILITY WITH A SPLIT HOME AGENT ARCHITECTURE''s co-pending application. The cross-referenced applications are hereby incorporated 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 separate communication modes are supported through MIPv6: bidirectional tunneling (BT) mode and route optimization (RO) mode. When the mobile node is not in the home network, the mobile IPv6 uses the home agent node to manage the forwarding of data services to the mobile node. [0003] When a mobile node moves to a foreign net...
