However, the ACL resources provided by the switching chip are very limited. Moreover, for some switching chips, the PDU processing process is before the ACL. If the message goes through the PDU process, it will not go through the subsequent ACL process, so , even if ACL is used, it cannot guarantee to eliminate the situation that the PDU sends the message to the CPU by mistake

The present application provides a packet loss processing method. The method includes: if it is determined that a target message is a message sent to the CPU by mistake, determining the reason for sending the target message; and determining the reason for sending the target message according to the sending reason The PDU entry hit by the target packet in the switching chip is used as the target PDU entry; the sending queue corresponding to the target PDU entry is determined as the target sending queue; by operating the target sending queue, it belongs to the target sending Subsequent packets in the queue are discarded. Since the switch chip sends the target message to the CPU, it will be accompanied by the sending reason of the target message. Through the sending reason, the PDU entry hit by the target message and the sending queue corresponding to the PDU entry can be found. By performing related operations on the sending queue, subsequent packets belonging to the sending queue can be discarded for processing, so that the sending of these packets is stopped, thereby preventing these packets from being sent by mistake.
Description
technical field [0001] The present application relates to the field of communication technologies, and in particular, to a packet loss processing method, apparatus, device, and computer-readable storage medium. Background technique [0002] At present, some switching chips are preset with Protocol Data Unit (PDU) entries when they leave the factory. These PDU entries can be used to identify some common packets, such as the Virtual Router Redundancy Protocol (VirtualRouter Redundancy Protocol). VRRP for short) messages, Intermediate system to intermediate system (Intermediate system to intermediate system, IS-IS for short) messages, and perform specified operations on these messages when they are received, for example, send them to the Central Processing Unit (Central Processing Unit) , referred to as CPU), packet loss, forwarding, redirection and other operations. Also, users can customize the PDU through manual configuration. [0003] The PDUs that come with some switch c...
