Problems solved by technology

However, due to the diversity of services undertaken by network devices, the forms of messages are various, and the keyword information in the messages is also quite different.
If the same network device extracts keyword information from different packets according to the same prefetching operation, some keyword information will be incomplete, so that the calculated forwarding path cannot be guaranteed to be optimal, affecting the forwarding of network devices performance

Abstract

Embodiments of the present invention provide a message data prefetching method, device, and network equipment, wherein the message data prefetching method includes: extracting the encapsulation feature of the message; according to the encapsulation feature, determining the The prefetch operation of the interface; according to the prefetch operation, the specified data is prefetched from the packet. Through this solution, the forwarding performance of the network device can be improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and network equipment for data prefetching of messages. Background technique [0002] When a network device forwards a message, it usually selects specific field information from the message as keyword information, such as source IP (Internet Protocol, Internet Protocol) address, source port number, destination IP address, destination port number and other information. Then use the preset routing algorithm to calculate the keyword information to obtain the optimal forwarding path corresponding to each message, and then assign each message to a different interface for forwarding. The network device needs to extract data from the Cache (cache) when performing calculations, which requires the network device to store the message in the Cache before forwarding the message, which seriously affects the efficiency of message forwarding. [0003] In order ...
