Problems solved by technology

[0018] However, when the binding process is performed with local proxies included only in the ISP, each local proxy bears too much processing load
Moreover, since more and more network devices are used in the local area, it is inefficient to use only the local proxy of the ISP without using the local network device to perform the binding process

Embodiment Construction

[0041] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0042] FIG. 6 shows an example of an Internet Protocol Version 6 (IPv6) network utilizing a home agent management device 610 according to the present invention. Referring to FIG. 6, a home agent management device 610 manages local first to third home gateways 620a to 620c and first to third home agents 630a to 630c included in an Internet Service Provider (ISP). In other words, when a network device capable of performing the function of the local proxy such as a local gateway exists locally, the local proxy in the ISP is unnecessary. A local gateway is used as a local proxy when the local gateway is operating normally. When a network device in the locality is used as a home proxy, the binding-related processing load concentrated on the ISP's home proxy can be significantly reduced.

[0043] When the local gateway in the locality fails ...

Abstract

A home agent management apparatus and method for routing a packet using a home network equipment as a home agent in a mobile Inter Protocol version 6 (IPv6) are provided. The home agent management apparatus includes a packet analyzer, which receives a packet and analyzes the packet; a database, which stores information indicating whether a home agent of a home network operates normally according to the result of the analysis; and a home agent function executor, which performs a home agent function in place of the home agent when the home agent does not operate normally. Accordingly, a load concentrated on a home agent of an Internet Service Provider (ISP) can be split.

Description

technical field [0001] The present invention relates to data packet routing using mobile Internet protocol version 6 (IPv6), in particular, to a home agent management device and method for routing data packets using a home network device as a home agent . Background technique [0002] In the mobile IPv6 system, regardless of whether the mobile node is currently connected to a local link (home link) or a foreign link, the unique local address of the mobile node can be used to find the location of the mobile node. The home address is the unique Internet Protocol (IP) address assigned to the mobile node in the home subnet prefix on the home link. [0003] When the mobile node is on the home link and a data packet is transmitted having the mobile node's home address as the destination address, one of the home agents on the home link uses conventional internetwork routing mechanisms to route the data packet. However, when the mobile node is not connected to a home link but is c...
