Embodiment Construction

[0026] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0027] FIG. 2 is a schematic diagram of information exchange between Diameter entities applied in the present invention, and the Diameter entities involved include a Diameter client (Diameter Client) and a Diameter server (Diameter Server).

[0028] The specific description is as follows:

[0029] The Diameter client initiates an application request to the Diameter server according to business needs. The request message sent may pass through multiple relay (Relay) proxies, and finally reaches the destination server. Therefore, a relay is a Diameter node. Attribute values ​​forward request and response messages to AVPs and domain routing tables. Relays do not make any policy decisions, so they do not inspect or alter non-routing AVPs, and never generate messages, without understanding the semantics of messages or non-routing AVPs.

[0030] Diameter servers are nodes...

Abstract

The present invention provides a method for realizing the fault switching. The method sends all the mutually being peer to peer terminal links obtained when a node operates the routing analysis to the message for the first time, and caches the routing result, meanwhile, one of the links is chosen for sending the message, and when the preferred link has a fault, the message is sent to the standby peer to peer terminal according to the cached routing result. The present invention adopts an improved domain routing processing method, to enable the Diameter node to be quickly switched to the standby links when the link has a fault, and the processing efficiency is improved, thereby the requirement of improving the reliability of the Diameter node is realized.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method for realizing failover. Background technique [0002] For commercially operated communication networks, AAA (Authentication, Authorization, Accounting, Authentication, Authorization, Accounting), that is, the authentication, authorization, and accounting system becomes the basis of its operation. The Diameter protocol family is a new generation of AAA technology, which has attracted much attention due to its strong scalability and security. In international standard organizations such as ITU (International Telecommunication Union), 3GPP and 3GPP2, Diameter has been officially regarded as the preferred AAA protocol for future communication networks such as NGN (Next Generation Network), WCDMA (Wideband Code Division Multiple Access) and CDMA2000. The use of various resources in the network requires mechanisms such as authentication, authorization, and accou...
