Problems solved by technology

[0004] In the process of realizing the present invention, the inventors found that because only the IP address and Transmission Control Protocol (Transmission Control Protocol, hereinafter referred to as: TCP) or User Datagram Protocol (User Datagram Protocol, hereinafter referred to as: UDP) port number were sampled by DFI information, and the existing application, through the TCP / UDP port number can not know its application type
Therefore, the DFI system cannot know what kind of applications are included in the data traffic on the IP backbone network and the flow direction of each application.

Abstract

The invention discloses an analyzing and processing method and an analyzing and processing system of traffic flow direction based on application. The analyzing and processing method of the traffic flow direction includes that: a traffic matrix analysis system (FMAS) obtains traffic flow direction data of all data flows in an Internet protocol (IP) backbone network according to flow direction information of Internet data center (IDC) data flows reported by an egress router of the IDC and border gateway protocol (BGP) routing information reported by a router of the IP backbone network; an application extractor (AE) which is disposed on an exit link of the IDC detects net load information of each data package on the IDC exit link thoroughly and obtains application information of each data flow on the IDC exit link combining characteristic fields of each application, wherein the application information includes IP address, application type and application name of each data flow; the AE reports the application information of each data flow on the IDC exit link to the FMAS; the FMAS analyzes traffic flow direction data of all data flows in the IP backbone network and the application information of all data flows on the IDC exit link and obtains traffic flow direction data of each application in the IDC. The analyzing and processing method is capable of obtaining data traffic flow direction conditions of applications in the network.

Description

technical field [0001] The present invention relates to communication technology, in particular to an application-based traffic flow analysis and processing method and system. Background technique [0002] In an existing Internet Protocol (Internet Protocol, hereinafter referred to as IP) backbone network, a deep flow inspection (deep flow inspection, hereinafter referred to as DFI) system is generally deployed. The DFI system reports the sampling data flowing through each link of the router to the DFI system through the router through the network data flow (Netflow) technology, which includes the source IP address, destination IP address, source port, destination port, etc. of each data flow information. After receiving these data, the DFI system combines the Border Gateway Protocol (BGP) routing information received from the IP backbone network router, and outputs the flow direction of each data flow in the IP backbone network after data processing and analysis Data, for...
