SENDING METHOD, PROCESSING METHOD, COMMUNICATION SYSTEM AND DEVICE FOR DATA FLOW INFORMATION

摘要

A sending method, a processing method, a communication system and a device for data flow information are provided to improve utilization rate of network resource. The sending method for data flow information includes that: the flow identification information of the received data flow and the flow statistical information are acquired; if the session identifier corresponding to the flow identification information is found according to the flow identification information, then the session identifier and the flow statistical information are sent to the netflow collecting system NDC. The utilization rate of the network resource can be efficiently improved by the methods, system and device.
