Abstract

The invention provides a flow switching method and device. The method comprises the steps of: detecting an accessed network device when the network device is carrying out flow switching, wherein the network device starts a stacking function in advance; after the accessed network device is detected, selecting the network device as a slave device; and synchronizing the local business environment information to the slave device so as to respond to the flow switching operation of the user, and switching the flow accessing a local front end device to the slave device. According to the embodiment, the flow interruption time in the flow switching process is effectively shortened.

Description

technical field [0001] The present application relates to the field of computer network communication, in particular to a method and device for traffic switching. Background technique [0002] Network devices running on the live network may often need to switch local traffic to another network device due to device failures, system software upgrades, and other reasons. When traffic switching occurs, usually, it is necessary to start a new system software on another network device, configure the same configuration environment as the network device on the network device, and switch the traffic on the network device to the network device . [0003] However, using the above solution to switch traffic may cause long-term interruption of network traffic. Contents of the invention [0004] In view of this, the present application provides a method and device for traffic switching, which are used to reduce the duration of traffic interruption during the traffic switching process....
