Title: COFLOW RECOGNITION METHOD AND SYSTEM, AND SERVER USING METHOD
Abstract:
A coflow recognition method comprises: a server obtaining data stream header information of data transmission in a network; obtaining stream layer data features, application layer data stream features, and terminal layer data features according to the data stream header information; obtaining a weight matrix by learning historical data in the network, wherein the weight matrix is used for minimizing a feature distance between data streams that belong to a same coflow, and maximizing a feature distance between data streams that belong to different coflows; calculating a feature distance between any two data streams in the network according to the measurement of the data stream layer data features, a distance between the application layer data stream features, a distance between the terminal layer data features, and the weighting matrix; classifying the data streams in the network into multiple cluster sets by means of a clustering algorithm according to the feature distance between any two data streams in the network, wherein each of the multiple cluster sets is a coflow.
