Fig. 3 is a data processing method embodiment flow chart of the present invention, and is as shown in Figure 3, and this method comprises:
After BNG receives data, to judge at first which user is these data belong to, can be according to the IP address or media interviews control (the media access control of data; Hereinafter to be referred as: the information that MAC) address etc. can the identifying user identity is judged; After judgement learns that these data belong to concrete which user again, search and this user's data processing policy information, and judge whether that according to this data processing policy information needs carry out DPI to the data that receive and detect; Said data processing policy information comprises two information tables; Be respectively customer service policy information and data flow state information; Wherein record the value-added service information that this user orders in the customer service policy information, record the type of service and the relevant information of every data flow of the BNG that flows through in the data flow state information.Should satisfy two conditions simultaneously if need carry out the DPI detection to the data that receive; Be in the data flow state information in relevant these data the type of service of data flow be recorded as the unknown; And this user of record had subscribed to value-added service in the customer service policy information; That is to say that these received data of BNG are new datas for BNG; Do not have before this and receive other data flow relevant, therefore in data flow state information, do not have the type of service record of relevant data stream with these data; In addition, this user must be the user who has subscribed to about the value-added service of certain type of service, judges according to above trigger condition.
If BNG according to customer service policy information and data flow state information judgement learn when the data that receive satisfy above two conditions simultaneously; BNG sends to the data that receive and is responsible for carrying out functional module that DPI detects and carries out DPI and detect; Data are carried out deep message detection processing requirements operator can carry out perception loaded service in the data flow; DPI is as a kind of message detection technique; Can the load (payload) of network data message be detected, thus the type of service of recognition data stream, and then reach the purpose that network traffics are controlled.Through can obtain the traffic type information of each data flow in the data to the depth detection of data load.
In detecting data after the type of service of each data flow; BNG is at first through searching the value-added service type that the user orders in the customer service policy information; And the type of service that contrasts which data flow is identical with the value-added service type that the user subscribes to; If there is the identical situation of type of service; Then type of service in the said data being identified with the identical data flow of value-added service type that said user orders, specifically is that the type of service of data flow that will be identical with the value-added service type that the user subscribes in data flow state information is labeled as " value-added service "; For the data flow of the value-added service type mismatch of other type of service and user subscription in the data, the type of service list notation with this data flow in data flow state information is " non-value-added service ".For example, the user subscribes to the value-added service relevant for " online game accelerations ", and in network is handed down to this user's the customer service policy information of BNG, will recording this user, to have subscribed to type of service be the information of the value-added service of " online game "; Carry out the DPI detection when the data of the information that BNG receives and to it after, obtain the type of service of each data flow in the data, for example comprise " online game " type of service and " visual telephone " type of service; Then; BNG contrast customer service policy information is with in the data flow state information type of service of the data flow of relevant " online game " being labeled as " value-added service "; The type of service of the data flow of relevant " visual telephone " is labeled as " non-value-added service ", uses when data are transmitted for follow-up.
