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

Embodiment Construction

[0043] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0044] The terminology used in the present disclosure is for the purpose of describing particular embodiments only, and is not intended to limit the present disclosure. As used in this disclosure and the appended claims, the singular forms "a", "the", and "the" are intended to include the plural forms as well, unless the context clearly dictates otherwise. It should also be understood...

Abstract

The invention provides a traffic switching method and device and forwarding equipment, the method is applied to a first processor in the forwarding equipment, the first processor is used for processing the traffic of a forwarding plane, and the method comprises the following steps: the first processor acquires a main forwarding table entry and a first standby forwarding table entry for sending thetraffic; and if the first processor detects that the main link for sending the traffic according to the main forwarding table item fails, sending the traffic through a first standby link according tothe first standby forwarding table item. Through the method, the traffic can be directly switched on the forwarding plane without being influenced by the control plane.

Description

technical field [0001] The present disclosure relates to the technical field of communications, and in particular, to a traffic switching method, device, and forwarding device. Background technique [0002] Such as figure 1 As shown, the service line cards of high-performance forwarding devices (such as routers or switches) generally adopt a transfer-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 for executing traffic sending and receiving, and the control plane is mainly used for protocol processing and delivery of forwarding table items. [0003] An important indicator of BFD detection performed in high-performance forwarding equipment is detection accuracy (sensitivity to perceive link failures), such as 10ms*3 (Note: the sending end sends a keep-alive...
