Embodiment Construction

[0023] Referring to FIG. 2 , flow analysis system 10 includes stage analyzer 310 , which replaces analyzer 300 of the flow analysis system of FIG. 1 .

[0024] The hierarchical analyzer 310 is used to perform successive levels of analysis of the communication traffic flow through the communication link 200' between the first network 100' and the second network 110'. Thus, hierarchical analyzer 310 performs a first level of analysis on the communication traffic flow, a second level of analysis is performed by analyzers 320a-320n, and a third level of analysis is performed by analyzers 330i-330j. The communication traffic analysis system 10 may have as many stages of analyzers as necessary to adequately analyze and classify the communication traffic according to the traffic size and speed of the data packets on the communication link 200'.

[0025] Hierarchical analyzers 310 and 320a-320n are connected through links 202a-202n, and the number of data packets through communication...

Abstract

The present invention provides a traffic analyzing system on a communications link having analyzer circuits connected to each other by a number of links, where each analyzer circuit has a data rate lower than the data rate of the communications link, and are adapted to perform respective different levels of analysis on packets. The information extracted from the packets analyzed at a first level of analysis by a first analyzer circuit is forwarded to a second level of analysis performed at a second analyzer circuit, where the additional analysis performed by the second analyzer circuit depends on the analysis performed by the first analyzer circuit. Such a system and associated method allows for an efficient, practical, and improved traffic flow analyses for computer networks to evaluate high-speed and heavy traffic flow, as well as for improved protocol analysis for emerging technologies.

Description

technical field [0001] The present invention relates to computer networks and, in particular, to analysis of communication traffic flows over high-speed connection links. Background technique [0002] Examining traffic flows can take a significant amount of processing time and power to monitor and classify them, and the volume and speed of traffic data, especially that of the Internet, is rapidly increasing. Since various types of processing are required to obtain semantic, reliable and useful network traffic classification and processing, the system for traffic flow analysis often encounters some problems at the layer of the traffic flow channel. obstacle. [0003] By classifying the communication traffic propagating around the data network, it is possible to determine the action to be taken for each communication traffic flow according to its classification. That is, classifying a communication traffic flow may allow network components to classify a data packet based on ...
