Embodiment Construction

[0035] In traditional technology, different IP addresses need to be used to access the primary server and the standby server, so when the primary server fails, the IP address of the primary server needs to be manually changed to the IP address of the standby server to achieve access to the standby server. Inconvenience to users and administrators.

[0036] At present, there is a technical solution capable of solving the above-mentioned technical problems. That is, both the first routing device connected to the primary server and the second routing device connected to the standby server store the IP address associated with the first server, that is, the preset southbound interface IP address and / or the preset IP address of the northbound interface. Priorities are pre-configured in the first routing device and the second routing device. When the primary server is available, the priority configured on the primary server is high priority, and the priority configured on the standb...

Abstract

The embodiment of the invention discloses a communication method, device and system, which are used for realizing automatic switching between servers and reducing the workload of users and managers. The communication system provided by the embodiment of the invention comprises a first server and a second server, the first server is used for acquiring a first mapping relationship and sending the first mapping relationship to the target equipment based on a border gateway protocol, wherein the first mapping relationship is a mapping relationship between an IP address associated with the first server and a local IP address of the first server, and the IP address associated with the first server comprises a preset southbound interface IP address and / or a preset northbound interface IP address;and the second server is used for obtaining the state of the first server and a second mapping relation, if the state is a fault state, the second mapping relation is sent to the target equipment based on the border gateway protocol, and the second mapping relation is the mapping relation between the IP address associated with the first server and the local IP address of the second server.

Description

technical field [0001] The present application relates to the field of network communication, in particular to a communication system, method and device. Background technique [0002] With the development of communication technology, cloud services are more and more widely used. For example, cloud services can provide users with services such as automatic deployment of network services and automatic operation and maintenance, so it is very important to ensure the normal operation of cloud services. In order to ensure the reliability of cloud services, the server that supports cloud service management needs to have a disaster recovery function, that is, when the primary server fails, the business can be switched to the standby server in time. [0003] Currently, servers supporting cloud service management have southbound and northbound interfaces. In the traditional technology, the internet protocol (internet protocol, IP) address of the southbound interface of the main ser...
