Message forwarding method and device and computer readable storage medium

Abstract

The invention discloses a message forwarding method and device and a computer readable storage medium, the message forwarding method is applied to a virtual forwarding router, the virtual forwarding router comprises a main control board, a main interface board and a standby interface board, and forwarding plane processes are deployed on the main control board, the main interface board and the standby interface board. Detection messages are transmitted between the main control board and the main interface board and between the main control board and the standby interface board through an internal media plane network, and the detection messages are processed by a forwarding plane process. The main control board receives detection messages of the main interface board and the standby interface board through an internal media plane network; the main control board determines in-place states of the main interface board and the standby interface board according to the detection message; and when the main control board confirms that the main interface board is offline, the main control board is switched from the main interface board to the standby interface board to forward the service message. According to the method, the internal media plane network is added to the virtual forwarding router, and the single board is directly detected to be offline on the forwarding plane, so that the in-place state of the single board can be quickly detected, the sensing time is shortened, and the requirement of quick switching of service flow is met.

Description

technical field [0001] The embodiments of the present invention relate to, but are not limited to, the field of network communication technologies, and in particular, relate to a packet forwarding method, apparatus, and computer-readable storage medium. Background technique [0002] In network function virtualization deployments, virtual forwarding routers that are responsible for virtualizing network processing functions are generally deployed in a distributed environment. In order to prevent service forwarding and processing functions from being affected even if a single network element fails, a virtual router will deploy active and standby routers. The interface board (Data Processing Unit, DP) is backed up, and the interfaces of the active and standby interface boards are aggregated and bundled. When the main interface board is offline, it can be switched to the interface of the standby interface board to continue processing packets sent and received, without affecting th...

Problems solved by technology

[0003] In related technologies, if the standby interface board needs to sense that the main interface board is offline, the control plane of the main control board (MainControl Processing Unit, MP) of the router needs to pass through the TIPC (Transparent Inter-process Communication) where the network card of the LINUX protocol stack is located. The network sends keep-alive messages to each other. For the safety of the entire device, the control plane lengthens the detection cycle time. After sensing that the main interface board is offline, it needs to notify the control plane of the standby interface board through the TIPC network, and then the control plane of the standby interface board goes offline. Notification is sent to the forwarding plane, and the forwarding plane can perform service switching, which takes a long time, and the time for business forwarding and packet loss is relatively long
