The invention provides a message statistics method and a network device. The network device comprises a central processing unit and a switch chip. The method comprises: the switch chip searching an identifier by acquiring a flow table entry of a received message; when the flow table entry lookup identifier indicates that the hardware flow table entry of the service flow to which the matched message belongs is not found in the user flow table, judging whether the service flow is a specified service flow to be counted or not, when the service flow is determined to be the specified service flow to be counted, copying a message and sending the message to the central processing unit, establishing a hardware flow table entry of the service flow by the central processing unit based on the copiedmessage, and setting a counter for the established hardware flow table entry to count the number of the messages of the service flow. Therefore, under the condition that the chip hardware does not support the netstream function, the hardware flow table item is established for the specified service flow to be counted through the central processing unit, the counter is arranged for the hardware flowtable item, and an in-direction message counting function can be achieved on an exchange chip of a current mainstream application.
Description
technical field [0001] The present application relates to the communication field, and in particular, relates to a packet statistics method and network equipment. Background technique [0002] Netstream technology is a statistical technology based on network flow information, which can collect and analyze service traffic in the network. Netstream provides packet statistics function, which can distinguish flow information according to the destination ip address, destination port number, source ip address, source port number, protocol number and tos (type of service) of the packet, and for different Independent data statistics for flow information. [0003] However, the switch chips currently used in mainstream applications do not support the hardware netstream function, which cannot meet the demand for traffic statistics in the inbound direction of network users. Contents of the invention [0004] The purpose of this application is to provide a packet statistics method an...
