Problems solved by technology

[0004] Embodiments of the present disclosure provide a method, device, and forwarding device for traffic switching, which can realize the separate linkage of BFD transfer and control, that is, when BFD detects a link failure, the forwarding plane and the control plane are processed separately to solve the problem that the forwarding plane is processed by the control plane. Affected by the capability, the traffic switching speed of the forwarding plane is too slow

Abstract

The present disclosure provides a traffic switching method, device, and forwarding device. The method is applied to a first processor in the forwarding device, and the first processor is used to process the traffic of the forwarding plane. The method includes: first processing The processor acquires the primary forwarding entry and the first standby forwarding entry for sending traffic; if the first processor detects that the primary link sending the traffic according to the primary forwarding entry fails, then according to the first The standby forwarding entry sends the traffic through the first standby link. Through this method, traffic can be directly switched on the forwarding plane without being affected by the control plane.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular, to a method, an apparatus, and a forwarding device for traffic switching. Background technique [0002] like figure 1 As shown in the figure, the service line cards of high-performance forwarding devices (such as routers or switches) generally adopt a forwarding and control separation architecture, that is, the data forwarding plane adopts NPU (Network Processing Unit, network processor) and the control plane adopts CPU (Central Processing Unit, central processing unit). processor), wherein the data forwarding plane is mainly used to perform traffic sending and receiving, and the control plane is mainly used for protocol processing and forwarding table item delivery. [0003] An important indicator of BFD detection performed in high-performance forwarding equipment is detection accuracy (sensitivity to sense link failure), such as 10ms*3 (Note: the sender sen...
