Problems solved by technology

[0003] Usually, when the message forwarding function is completed through the kernel module, the existing method upgrades by uninstalling the old version of the kernel module and loading the new version of the kernel module, so it is impossible to achieve non-destructive upgrade of online services; When executing in user mode, a new process is created while the original process provides services, and the new process inherits the file descriptor of the original process and then provides services for upgrading. However, this method is limited by forwarding performance and cannot be used in large traffic and high concurrency. use in the scene

Abstract

The embodiment of the application discloses an upgrading method and device. A specific implementation of the upgrading method comprises the following steps: checking target message forwarding application information in response to receiving an upgrade command containing the target message forwarding application information, wherein the upgrade command is used to indicate that the original messageforwarding application is upgraded to the target message forwarding application; obtaining the target message forwarding application in response to confirming that the verification passes; upgrading the original message forwarding application running in a second memory area to the target message forwarding application when the number of connections established in the second memory area is a presetvalue; and upgrading the original message forwarding application running in a first memory area to the target message forwarding application when the number of connections established in the first memory area is the preset value. The implementation of the upgrading method improves the adaptability of hot upgrading under large traffic and high concurrent scenarios.

Description

technical field [0001] The embodiments of the present application relate to the field of computer technology, specifically to the field of Internet technology, and in particular to an upgrade method and device. Background technique [0002] With the development of computer technology, due to the continuous consideration of product iteration and the handling of abnormal situations, the hot upgrade of message forwarding applications is an unavoidable process. Currently, packet forwarding applications in the industry adopt upgrade methods in different application scenarios, mainly including replacing kernel modules, replacing original processes with new processes, and so on. [0003] Usually, when the message forwarding function is completed through the kernel module, the existing method upgrades by uninstalling the old version of the kernel module and loading the new version of the kernel module, so it is impossible to achieve non-destructive upgrade of online services; When ...
