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 an IP (Internet Protocol) address negotiation implementation method based on a PPP (Public Protocol Protocol), which comprises the following steps: configuring the same addresspool for each node of a full-connection network to carry out dynamic negotiation, implementing a negotiated main body function in a plug-in, and distributing IP address pairs by a calling party. Compared with the prior art, the invention has the advantages that: aiming at the situation that the existing traditional PPP-IPCP negotiation mode cannot meet the communication requirement of a point-to-point full-connection network, a mode of applying a PPP-IPCP enhanced plug-in is provided, so that in a network system, two communication parties at any two points can automatically allocate IP addresses in a dynamic negotiation mode, address conflicts between nodes cannot be caused, and message intercommunication is realized.

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...
