Abstract

The invention discloses a disaster tolerance method and device for remote service calling. The method comprises the steps: building a remote calling connection between a client and a server, and initiating a calling request to the server when the remote calling needs to be initiated to the server; if calling fails, when it is detected that the current retry frequency in the message corresponding to the calling request is smaller than the preset maximum retry frequency, the calling request is packaged into an updated message, and 1 is added to the current retry frequency; and sending the updated message to an external request delay queue for caching, and after the preset retry condition is satisfied, forwarding to initiate a retry call request to the server, thereby realizing caching of thecall request corresponding to the call failure, not only improving the caching of the call request when a large number of request failures occur at the same time, but also improving the capability ofretrying the call request.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a disaster recovery method and equipment for remote invocation of services. Background technique [0002] Service remote invocation increases the uncertainty of service invocation because it involves network transmission and third-party services. Remote calls fail when network congestion occurs or third-party services are unavailable. In order to solve the problem of remote call failure, there are the following two commonly used disaster recovery methods in the prior art: [0003] (1) The client retries. In the disaster recovery method of client retry, the client node locally initiates the scheduled task retry call. In the disaster recovery method of client retry, due to the limitation of local memory space, the number of tasks in the retry queue is limited; when there are a large number of call failures at the same time, the local retry queue will expand rapidly, ...
