Network communication data flow information statistic system and method

Abstract

The invention discloses an information statistic system of network communication data stream, comprising a main control system, a communication interface system and a business function system; the invention also provides an information statistic method of network communication data stream, which is as follow: a received or forwarded network communication data stream is mirrored to the business function system via the communication interface system; after the received network communication data stream is sampled, filtered and statistically processed by the business function system, the statistical result of the network communication data stream is sent to communication internal system; the received statistical result is sent to a distal server via the communication interface data stream. The invention has the advantages that the limits of the network interface of the monitored equipment and the bandwidth provided by network operator are avoided when the sampled data stream is sent to the monitor server via the monitored equipment in the prior art; during the process that the network communication data information is statistically processed, the original communication performance ofthe communication interface system is guaranteed to be not affected.

Description

technical field [0001] The invention relates to the field of computer network communication, in particular to a system and method for statistics of network communication data flow information. Background technique [0002] Statistics on network communication data flow information is the basis for network application analysis and monitoring, and is widely used in traffic monitoring, network billing, network security monitoring and prevention, network resource optimization and construction, etc. [0003] The statistics of network communication data flow information can be roughly divided into two categories: the first type of information is the information carried by the data flow itself. That is, the source IP address of the message, and the IP address of the interface where the message is to be delivered to the destination device, that is, the destination IP address of the message, the length of the IP message, etc.; the second type of information is the operation informatio...

AI Technical Summary

Problems solved by technology

[0015] 1) The available information is not comprehensive enough: only the information carried by the data stream itself, that is, the first type of information can be obtained; the second type of information cannot be obtained

[0016] 2) There is nothing that can be done when the data flow of the monitored object exceeds the bandwidth of the interface

[0017] 3) Even if the two-way communication data flow of interfaces 1 and 2 does not exceed the bandwidth of interface 3, since the monitoring equipment is located at the remote end, it needs to be transferred through the network operator's line in the middle, and the bandwidth may be limited by the bandwidth service provided by the network operator. limit

[0024] Since the communication interface system needs to perform sampling and filtering, and send the filtered network communication data flow and data flow sending and receiving interface information to the business function system, the burden on the communication interface system processor is increased, and more equipment is occupied. resources, affecting the performance of normal data communication of the communication interface system
