DATA PROCESSING METHOD, BROADBAND NETWORK GATEWAY, POLICY CONTROLLER AND ACCESS DEVICE

摘要

A data processing method, broadband network gateway, policy controller and access device are provided by the embodiments of the present invention. The method includes: receiving data, judging if it is necessary to perform deep packet inspection to the data according to the data processing policy information of the user that the data belongs to; and if it is, performing deep packet inspection to the data, acquiring the service type of each data stream in the data; identifying the data stream in the data, wherein the service type of the data stream is the same with the value-added service type that the user subscribes, according to the data processing policy information and the service type of each data stream in the data; scheduling and forwarding the identified data stream. The embodiments of the present invention perform deep packet inspection process to the flow of the internet application according to the deep packet inspection service policy, perform subdivision and identification to the service data, and preferentially schedule a part of the flow through the planed service channel, thus the quality of traffic service can be improved.
