Problems solved by technology

[0004] Since the first network device needs to periodically send BFD packets, such as sending a BFD packet every millisecond, the BFD packets need to occupy a large amount of CPU (Central Processing Unit, central processing unit) resources, causing relatively large Burden, affecting the processing performance of the first network device

Abstract

The invention provides a processor and a BFD message transmission method. The processor comprises a control core and a data core, wherein the control core is configured to determine session information of a BFD session established by first network equipment and second network equipment, the session information comprises a first message transmission interval, and a first BFD message is transmittedto the second network equipment by utilizing the first message transmission interval; the control core is further configured to synchronize the session information to the data core; the data core is configured to receive the session information synchronized by means of the control core and obtain a second message transmission interval, and the second message transmission interval is less than thefirst message transmission interval; and the first message transmission interval in the session information is updated to the second message transmission interval, and the first BFD message is transmitted to the second network equipment by utilizing the second message transmission interval. Through the adoption of the processor and the BFD message transmission method, the performance pressure of the control core can be alleviated, and the overall processing performance of the network equipment can be improved.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a processor and a BFD message transmission method. Background technique [0002] BFD (Bidirectional Forwarding Detection, bidirectional forwarding detection) is a general, standardized, medium-independent and protocol-independent fast fault detection mechanism, which is used to detect the link connectivity status in the IP network and ensure that the communication between network devices can be quickly detected faults, so that timely measures can be taken to ensure the continuous operation of the business. BFD can quickly detect the failure of the bidirectional forwarding path between two network devices for various upper-layer protocols (such as routing protocols, etc.), and can provide millisecond-level detection. [0003] After the first network device establishes a BFD session with the second network device, the first network device periodically sends a ...
