Problems solved by technology

[0008] In order to overcome the above-mentioned shortcomings of the prior art, the present invention provides a method for implementing IP address negotiation based on the PPP protocol. The present invention aims at the situation that the existing traditional PPP-IPCP negotiation method cannot meet the communication requirements of the point-to-point full-connection network. A way of using PPP-IPCP enhanced plug-in, satisfying that in a network system, any two communication parties can automatically assign IP addresses through dynamic negotiation, and will not cause address conflicts between nodes, and realize message sharing intercommunication

Embodiment Construction

[0022] The present invention aims at the fully connected network, and sets the same address pool on each node, which contains a sufficient number of address pairs. Use unique addresses when communicating with different nodes. The technology is implemented in the form of an enhanced plug-in to ensure that the corresponding processing flow is added without affecting the PPP-IPCP function. The main functions of the negotiation are realized in the plug-in to ensure the transplantation and expansion of functions in the future. According to the process, it can be divided into initialization, the calling party initiates address pair negotiation, and the called party accepts or rejects (the calling party changes the address pair for renegotiation or negotiation failure).

[0023] 1. Initialization

[0024] a) The setting of address pairs in the address pool: determined according to the node with the largest number of links in the network, the calculation rule is: S=N*2-1, where S is ...

Abstract

The invention discloses a method for realizing IP address negotiation based on the PPP protocol. Each node of the fully connected network is configured with the same address pool for dynamic negotiation. The main function of the negotiation is realized in the plug-in, and the calling party is responsible for the IP address Assignment of address pairs. Compared with the prior art, the positive effect of the present invention is: the present invention proposes a method of using PPP-IPCP enhanced plug-in for the situation that the existing traditional PPP-IPCP negotiation method cannot satisfy the point-to-point full-connection network communication requirements , satisfying that in a network system, any two communicating parties can automatically assign IP addresses through dynamic negotiation, without causing address conflicts between nodes, and realizing message intercommunication.

Description

technical field [0001] The invention relates to a method for realizing IP address negotiation based on PPP protocol. Background technique [0002] PPP (Point-to-Point Protocol) is a link layer protocol designed for simple links that transmit data packets between peer units. The link provides full-duplex operation with sequential transmission of packets. The application of PPP is mainly to establish a point-to-point connection for communication through dial-up or dedicated line, and it has become a common technical means for connecting various hosts, bridges, and routers. The underlying physical transmission medium of PPP communication can be serial cable, optical fiber and Ethernet, etc., which has a wide range of applicability and can be applied to information exchange between various occasions. [0003] PPP has three main components: encrypting data packets on the serial line; connection control protocol (LCP) for establishing, configuring and detecting data link connect...
