Problems solved by technology

[0004] When a network device forwards packets, the packets can be classified into protocol packets and data packets. Since the flow of data packets is much larger than the flow of protocol packets, the buffer queue will be full of more data packets. , protocol packets that are crucial to packet forwarding are discarded by network devices, causing network devices to malfunction when forwarding packets, thus reducing the reliability of network devices

Abstract

This specification provides a message buffering method, device and network equipment, which relate to the technical field of communication. A message caching method, applied to forwarding chips, including: parsing the received message to determine the priority of the message; if the occupancy of the own cache queue is greater than or equal to the packet loss threshold corresponding to the priority, then discarding message; if the occupancy of its own cache queue is less than the packet loss threshold corresponding to the priority, the message will be written into the cache queue; among the adjacent priorities, the packet loss threshold corresponding to the high priority is greater than the low priority The corresponding packet loss threshold. Through the above method, the buffering and processing of high-priority protocol messages can be guaranteed, and the reliability of network equipment can be improved.

Description

technical field [0001] The present specification relates to the technical field, and in particular, to a message caching method, apparatus, and network device. Background technique [0002] With the popularization and development of the network, the complexity of the network is also increasing, and the demand for the forwarding capability of the network equipment is higher and higher. The network device includes multiple network ports, forwarding chips, and processors. When the network device forwards packets, the forwarding chip receives traffic from multiple network ports, and writes the packets in the traffic to the buffer queue of the forwarding chip for processing. The cache is sent to the processor for processing through the cache queue. [0003] The buffer queue can be understood as a memory, which forwards the buffered packets according to the first-in, first-out rule. When the packets written to the cache queue exceed the storage space of the cache queue, the exce...
