Problems solved by technology

[0003] However, single board hot backup needs to use the backplane bus of the chassis for real-time synchronization of dynamic data, so the active and standby single boards must be located in the active and standby units of the same chassis
When the entire chassis is powered off, the main and standby boards are powered off, so reliability cannot be guaranteed
Static data backup cannot achieve the continuity of service provision, and the service will inevitably be interrupted during the process of reloading and restoring data

Embodiment 1

[0032] Take the situation where the primary and secondary servers are deployed on the same LAN as an example:

[0033] 1) Install network elements on two servers A and B: HLR3000, DNSS, SAG, SMS center.

[0034] 2) Correctly set the two servers and configure a common floating IP that does not conflict.

[0035] 3) Set the condition for the HA control software to trigger the master / standby switchover to be unable to use the ping command to connect to the softswitch IP.

[0036] 4) After the configuration is complete, make sure you can use the ping command to connect to the softswitch IP, so that the HA dual-machine backup will enter the normal working mode. Assuming that server A is the master, server A keeps sending ping messages and waits for a response. Log in to the maintenance system through telnet, and check the status of the active and standby servers, such as local status, peer status, floating IP, and set switching conditions. Configure the network element data of th...

Embodiment 2

[0041] Take the situation where the primary and secondary servers are deployed in different cities (city X and city Y) and the primary server suddenly loses power as an example:

[0042] 1) Install network elements on the two servers respectively: HLR3000, DNSS, SAG, SMS center.

[0043] 2) Make correct settings on the two servers and configure a common floating IP that does not conflict.

[0044] 3) After the configuration is complete, the two servers enter the normal working mode. Assuming that the server in X city is the main server, log in to the maintenance system through telnet, and check the status of the primary and backup servers, such as local status, peer status, and floating IP. Configure the network element data of the primary server, configure a communication link between the SAG and the base station, and the entire system can normally perform wireless telephone communication services. The base station and the server are not under the same network. But the comm...

Embodiment 3

[0049] The present invention also proposes a device for realizing the above method, which device includes the following units:

[0050] The deployment unit is used to deploy the first and second servers, specifying the IP address commonly used by the two servers, that is, the floating IP;

[0051] Monitoring unit, the two servers monitor each other's status through heartbeat, and perform real-time data synchronization;

[0052] The switching unit is configured to update the floating IP from the first server to the second server when the first server is abnormal, so that the second server takes over the business of the first server through the floating IP.

[0053] Preferably, the deployment unit specifically includes the following units:

[0054] The address pairing unit is used for floating IP broadcasting the MAC addresses of the first and second servers. After both parties have received the broadcast message sent by the other party, if they judge to use a common floating I...

Abstract

The invention discloses a method for achieving high reliability of key equipment. The method comprises the following steps: deploying a first server and a second server; appointing an IP address, namely a floating IP shared by the two servers; mutually monitoring states of the two servers through heartbeat, and performing real-time data synchronization; when the first server is abnormal, updating the floating IP to the second server from the first server, and taking over the service of the first server from the second server through the floating IP.

Description

technical field [0001] The invention relates to a network communication method, in particular to a method, device and system for realizing high reliability of a server. Background technique [0002] In an IP-based network communication system, the reliability of backbone telecommunication equipment is very important. At present, a method to achieve high reliability is single-board hot backup. The boards are called the active main control board (Master) and the standby main control board (Slave). Among them, the active main control board is the core of the control plane, and communicates with the external and service boards to complete the normal functions of each module in the system; the standby main control board is only used as the backup of the active main control board, and communicates with the external and The service board is not communicating. Dynamic data such as state machine, control block and other data during the operation of the active single board are synch...
