Abstract

The invention discloses a network flow connection behavior characteristic analysis method based on a network flow connection graph. The method comprises that a node determination rule is set, and a node object is determined; a side generation rule is set, and a side interaction mode is determined; node filtering and grading rules are set, and main nodes are extracted and graded; side filtering and grading rules are set, and main sides are extracted and graded; and a network flow connection graph based on the port type amount and a network flow connection graph based on the network flow connection amount are generated, and the two connection graphs are combined to analyze the characteristics. According to the network flow connection behavior characteristic analysis method based on the network flow connection graph, large-scale communication network flow behavior can be comprehensively and accurately described in various graph forming manners, complex network scales at present can be adapted to, and the network flow behavior characteristics can be comprehensively and accurately extracted and analyzed.

Description

technical field [0001] The invention belongs to the technical field of network flow behavior analysis, and in particular relates to a network flow connection behavior feature analysis method based on a network flow connection graph. Background technique [0002] In a communication network, a network flow refers to a sequence of packets with certain properties transmitted through the network. Specific attributes can be determined according to the needs of the research, such as the aggregation of flow information sequences with the same five-tuple (source host IP address, destination host IP address, source host port number, destination host port number, and communication protocol) into bearer network information a network stream. [0003] Network flow behavior characteristics usually refer to the behavior characteristics of a single or multiple network flows, including application layer flow behavior characteristics and transport layer flow behavior characteristics. The anal...
