Method for distributing addressing section between DSLAM apparatus

Abstract

The method includes following steps: a virtual LAN is set for intercommunication between IP-DSLAM, and an address pool is set at a part of IP-DSSAM for connecting users; when IP-DSLAM starts up, first it is decided if there is an available address pool for using by users, if not, after it studies to the first IP-DSLAM with preset address pool, then sends the address request message to it; the IP-DLAM receives the request for address field, and decides if there is address field to allocate, if yes, then removes the allocated address field to form distributing address field that is attached to configuration parameter, then distributes it as ACK form; the IP-DSLAM of requesting address field receives the ACK and generates the local address pool; if no address field can be allocated , NCK message will be transmitted; if IP-DSLAM has a address pool , then transmits a declaration message to other IP-DSLAM.

Description

technical field [0001] The invention relates to a method for distributing address segments, in particular to a method for distributing address segments between DSLAM (Digital Subscriber Line Access Multiplexer) devices. Background technique [0002] With the development of network technology, broadband access has become a dominant user access mode at present. Broadband access generally includes methods such as ADSL, VDSL, and Ethernet. According to the operation needs of operators, all these methods require the process of broadband dial-up and authentication. After the authentication phase is completed, IP address allocation is usually required, the purpose is to assign an IP to the client so that the end user can communicate. At present, most IP-DSLAMs have integrated basic authentication (such as 802.1x authentication, PPPoE authentication and termination) and IP address allocation and management functions into the DSLAM equipment. In this way, the upper-level equipment ...

AI Technical Summary

Problems solved by technology

[0004] At present, IP-DSLAM assigns IP through the DHCP protocol, which has the following defects: (1) addresses cannot be shared, resulting in waste; (2) address pools are scattered and not easy to manage

However, in some cases, it may cause performance problems, for example: if only one device in a group can act as a server, the rest of the devices can only be used as ordinary clients; in this way, each client must frequently send address requests to the server and address release messages; when the number of users is large, address application may be slow

[0006] Each client will continue to apply for an address from the server as the user's online request increases; this process is frequent and long-term, which will cause the client and server to always have address application or release message interaction; when the user goes online frequently , it will increase the burden on the server, resulting in a direct drop in its processing capability, resulting in reduced bandwidth
