Method of non-allocation indifferent accessing of mobile IP terminal

Abstract

This invention discloses a random connective method of movable IP terminal without collocation. When the movable terminal is linked to the acting node of other place, send the movable terminal registering information to the acting node of other place, the agent of other place receives the IP address; the agent of other place receives the movable terminal registering information and sends movable terminal adding information to all nodes, and the information includes IP address of the movable IP terminal, interface IP network address of the agent; each network node sets information form of movable users and stores the information in the information form; according to the corresponding relation between the IP address of the movable IP terminal in the information form and the interface IP address, establish the direct communication channel from the access terminal to the movable IP terminal. In this way, it avoids the flux centralization between the home agent and abroad agent and improves the utility efficiency and performance of the network.

Description

technical field [0001] The invention relates to a method for random access of a mobile IP terminal without configuration. Background technique [0002] At present, the standard mobile IP protocol for IP terminal mobility is mainly related documents formulated by IETF, mainly including: RFC2002, RFC2003, RFC2005, RFC2006, etc., which can realize the random movement of mobile IP terminals in the network without requiring Any configuration is performed on the IP terminal, and the IP address of the mobile IP terminal is not modified, including manual or automatic modification. [0003] Home Agent: There is a router or switch connected to a port before the mobile IP terminal moves, and it keeps the current location information of the mobile terminal all the time. Foreign Agent: A router or switch that has a port connected to the mobile IP terminal after it moves. In the existing standard mobile IP protocol, the access process of mobile IP terminals without configuration is show...

Problems solved by technology

This will inevitably lead to a very concentrated traffic on the relay channel between the home agent and the foreign agent, resulting in a communication bottleneck

However, at this time, other relay channels still appear to be relatively idle, and false network congestion occurs.

Therefore, the efficiency and performance of the network will decrease, and the implementation of IP service quality assurance will become very difficult.

As shown in Figure 2, the home agent is the switch SW1, and the foreign agent is the switch SW4. When the IP terminals T1~T4 access the mobile IP terminal MT at the same time, the network proposes centralized bandwidth for the trunk link L1 through the switches SW3, SW2, and SW1. Requirements, 4 service channels are required in the figure, and the 4 dotted lines in the figure represent service channels, but the trunk links L2 and L3 are not used, resulting in false network busy conditions
