Abstract

The invention discloses IP address distributing method and system. In the method, a current network element sends an IP address request message carrying identification information of the current network element to adjacent network elements; the current network element receives an IP address distributing messages which carry the identification information of the current network element and are from an IP address server from the adjacent network elements, acquires an IP address distributed by the IP address server for the current network element from the distributing messages and allocates the acquired IP address to the current network element; and the current network element is set to be an IP relay network element to act for other network elements to apply the IP address from the IP address server. The invention realizes the convenient and fast interworking among IP layers of communication equipment, increases the usability and flexibility of a system, and enhances the performance of the system.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and system for allocating IP addresses. Background technique [0002] In actual use, in order to realize the intercommunication of the IP layer between the communication devices, it is necessary to assign an IP address to the communication devices. That is to say, on the premise of having an IP address, after the communication device is powered on, it can realize intercommunication with other devices at the IP layer. [0003] Currently, a Dynamic Host Configuration Protocol (Dynamic Host Configuration Protocol, referred to as DHCP) is usually used to allocate IP addresses. The DHCP protocol requires both the server and the client to be on the same network segment, that is, IP address allocation needs to be performed within a LAN. In order to solve the problem that the DHCP server and the terminal are not in the same LAN, the extended DHCP protocol uses the DHCP relay...
