Based Application Layer Network Traffic Monitoring

Lead to the more and more high, network scale of gradually complicated, network speed of network structure fleetness since Internet technology fleetness develops, expand, the various network transmission agreement uses at the same time , these factors bring about the administrative no easily unified network problem. How to resolve these problems , provide the reference basis to the network administrator assignment to network resource and the rise to network function, require that supervisory control and rate of flow guarding key resource in network , carrying out rate of flow at the same time are analytical right away.And the application rate of flow having brought forward the ability studying voluntarily owing to having that the data excavates distinguishes the main body of a book monitoring a technology , make use of a data to excavate the sum machine study technology , not classification data stream is used as an observed data , use the deep data bag to check a technology, the clustering on using application agreement analyses, with whose automation classification, come to forecast the type applying newly afterwards, the rate of flow being in progress monitors and analyses, supervisory control system divides the application rate of flow into big two parts, Monitor the part and the analytical offline backstage part on line, to improve entire analysis and to monitor process efficiency and accurate degree.Simulation by the fact that general interface rate of flow monitors the network and to simulated software of network simulation, the network model reaching a nowadays increases by with network node number exponent level, characterization difficulty , P2P applying newly if P2P applies and the rate of flow having increased a network appearing on VoD and VoIP still show whose long pertinent characteristic property as one kind of application.
