Problems solved by technology

In this case, it is possible that the user IP addresses of a certain BRAS have been exhausted, while the IP addresses of other BRAS devices still have a large number of remaining IP addresses, thus adopting distributed BRAS may cause a waste of IP address resources

Embodiment approach

[0014] The present invention can be divided into three flow processes to implement:

[0015] Configuration process:

[0016] 1. During the initial configuration, the configured address segment is the shared IP address segment of several BRAS device access users. Including DHCP Server configuration or local IP Local Pool configuration. In the shared IP address segment, specify an address segment for each BRAS as the address segment assigned by the BRAS by default, and this address segment is called the local address segment of the BRAS.

[0017] 2. Configure the access information of the BRAS device that shares the address with the local machine, mainly the interface IP address of the BRAS layer-3 interface and the BRAS interface MAC address.

[0018] 3. Configure the internal address management protocol between the BRASs, communicate through the MAC addresses of the BRASs, and notify and update the use of the shared IP address segment.

[0019] Address application process: ...

Embodiment approach

[0030] Hammer 10000 completes the embedded BRAS solution, and can choose the configuration method of multiple BRASs sharing IP address segments.

[0031] Hammer 10000 provides command line and network management interface to configure the range of shared IP address segment, and configure the information of each Hammer 10000 sharing this IP address segment and the default local address segment.

[0032] Configure the Hammer 10000 to provide PPPoE user access services. After the user sends a PPPoE dial-up authentication request and passes the authentication, he applies for an IP address from the Hammer 10000. Hammer 10000 first applies for an IP address from the local address pool. If the local address pool is exhausted, it will apply for an address from the idle Hammer10000 through the internal address management protocol. After the application is successful, the address will be allocated to the user, and the user will use this address to access the Internet.

Abstract

In the method, a field or a number of fields of shared IP address is disposed for a number of BRAS devices and local address field out from the shared IP address is disposed to each BRAS as each BRAS can carry on communication through internal address management protocol between each BRAS to exchange IP address distribution information and to apply IP address to each other. IP address out of local field address should be distributed to the user when each BRAS receives user switch in application. If the local field address is exhausted the application is switched to the other BRAS which has idle address and shares IP address with the said BRAS and the BRAS distributes the address to the user as well as to retransmit it as relevant route. If there is no idle address at all the other BRAS the user is refused to switch in.

Description

Technical field: [0001] The invention relates to the field of broadband network communication, in particular to a method for distributing user IP (Internet Protocol) addresses of distributed BRAS (Broadband Access Authentication Node). Background technique: [0002] At present, with the rapid growth of broadband users, the original independent centralized BRAS mode is gradually replaced by the decentralized BRAS mode. However, while the distributed BRAS reduces costs and improves efficiency, it also brings about complex management and operation problems, especially the low efficiency of IP address management for access users. [0003] BRAS generally adopts built-in address pool, DHCP proxy client, and Radius to manage user addresses in three ways, all of which need to assign a fixed IP address to BRAS in advance for user IP address allocation. The IP address management module of the BRAS only configures the IP address segment used by the users accessing the local machine, a...
