Problems solved by technology

However, in the non-preemptive mode, when a special situation occurs, such as when both the main service board and the standby service board fail and recover at the same time, according to the rules of the non-preemptive mode, the main service board and the standby The current status is normal. The ID of the service board currently in use saved in the main control board corresponding to the active service board is different from the currently used service board ID saved in the main control board of the standby service board. Traffic forwarding will lead to inconsistent traffic direction

Abstract

The application provides a flow forwarding method and device based on flow definition. The flow forwarding method comprises: when one business board of a device is detected to be resumed from an abnormal state to a normal state, a main control board determines whether a working mode of a current business board is a non-preemptive mode; if so, a role of the device in a VSM network is determined; when the device is a master device, a business board dynamic identifier is synchronized to a slave device; when the device is a slave device, a business board dynamic identifier stored by the device isupdated by using the obtained business board dynamic identifier of the master device, wherein the business board dynamic identifier is a currently used business board identifier stored in a main control board of each device; and according to a preset flow definition forwarding strategy, a flow forwarding direction is controlled. According to the application, the flow can be forwarded normally based on the all-the-time consistent mode of the business board dynamic identifier of the slave device and the business board dynamic identifier of the master device.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a flow definition-based flow forwarding method and device. Background technique [0002] With the continuous expansion of the network scale, there are more and more network failure points, and the complexity of configuration and maintenance is greatly increased. In order to simplify the complexity of networking and facilitate device configuration and maintenance, VSM (Virtual Switch Matrix) technology can be used to virtualize multiple physical devices into one logical device for management and use. Each member device in the VSM network is divided into two roles: Master (primary member device) and Slave (standby member device). The Master is responsible for managing and controlling the entire VSM system, and the Slave can forward data services while being controlled and managed by the Master. [0003] In addition, in order to realize flexible scheduling of t...
