Abstract

The invention provides a network accurate packet loss monitoring method and a switch chip. The method comprises the following steps: determining message characteristics of a message flow to be monitored; respectively setting a first mark and a second mark in flow statistical table entries of a second message processing module and a third message processing module, and adding the first mark to the message in the first message flow by the first message processing module according to the received message characteristics of the first message flow; enabling the first message processing module to send the first message flow added with the first mark to the second message processing module and the third message processing module; and enabling the second message processing module and the third message processing module to count the number of messages in the first message flow in the first period according to the first mark. According to the invention, specific network data traffic is effectively monitored in real time.

Description

technical field [0001] The invention relates to the field of data communication, in particular to a network accurate packet loss monitoring method and a switch chip. Background technique [0002] From the point of view of network equipment, network packet loss means that the data packet entering the network equipment cannot be forwarded out from the predetermined network equipment outlet, that is, the data packet is lost. There are many reasons for the failure of normal forwarding on network devices, such as port packet inspection failure, VLAN inspection failure, route does not exist, congestion discard, ACL (Access Control List: Access Control List) rule filtering, etc. [0003] For network equipment, network packet loss monitoring monitors the data flow entering the network equipment and the traffic forwarded from the network equipment, and judges the forwarding status of the data flow of the network equipment according to the size of the incoming and outgoing data traffi...
