Method and device for detecting server state

Abstract

The invention discloses a method and a device for detecting a server state, which are used for realizing the server state detection by using actual services, making the detected server state more accurate on the premise of effectively determining the server state in time and avoiding misjudgment caused by link flash. The server state detecting method provided by the invention comprises the following steps of: determining a server in the normal state to which the current authentication request message is required to send, sending the authentication request to the server, starting a failure detection timer corresponding to the server when the authentication request fails, and counting the times of continuous failure of the authentication request sent to the server through an authentication request failure counter corresponding to the server, wherein the authentication request failure counter is reset when a response message fed back by the server is received; and the server state is upgraded into the failure state when the failure detection timer is overtime and the counting value of the authentication request failure counter exceeds the preset first threshold value.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a server state detection method and device. Background technique [0002] In the CDMA2000-EVDO mobile communication system, when the user's access terminal (AT) accesses the access network (AN) for the first time, the AN usually completes the access authentication for the user, that is, according to the user's account information (including user name and Password) constructs an authentication request message (A12 Access Request) and sends it to the access network authentication, authentication, and accounting (AN-AAA) server. After receiving the authentication request message, the AN-AAA server , to feed back the response message of access acceptance (A12 Access Accept) or access rejection (A12 Access Reject). If the AN-AAA server runs abnormally or the host where it resides fails, the AN will not receive a response message after sending the authentication request message...

AI Technical Summary

Problems solved by technology

[0003] In order to determine the operating status of the AN-AAA server, the commonly used solution in the prior art is to use a ping detection mechanism, that is, to send a ping request to the AN-AAA server periodically, and determine the server status according to the response, but this solution can only reflect the server host The running status of the server cannot reflect whether the server business is normal

Another solution can be to construct detection users and regularly send authentication request messages to detect the status of the AN-AAA server, but this needs to avoid the duplication of constructed detection users and actual commercial users. In addition, this method may be harmful to AN-AAA The statistics of the server bring a certain amount of interference, and the implementation and operation and maintenance have a certain complexity

[0004] In addition, AN-AAA server failure detection also needs to avoid misjudgments caused by link flashes, that is, during link flashes, AN-AAA server operates normally, but The road may be restored soon. In this case, if the AN-AAA server is considered to be faulty and an alarm is reported, it will bring unnecessary trouble to the operation and maintenance of the network that often occurs intermittently.
