Preferred embodiment 3
This preferred embodiment is blocking-up to the P2P data flow based on Transmission Control Protocol and Flow Control, is introduced respectively below to blocking-up method and flow control method:
(1) blocking-up method.
Can be the combination of following three kinds of methods to the blocking-up of P2P data flow, paralleling model P2P scrambling device can be switched to other method when a kind of method of discovery is invalid blocks again.
First method: unidirectional transmission RST bag method.Namely the paralleling model P2P scrambling device client (Client) that disguises oneself as sends RST bag to server (Server), or the Client that disguises oneself as sends RST bag to Server, makes link chain rupture, has reached by the barrier effect of control flow check.
Second method: two-way transmission RST bag method.Namely the paralleling model P2P scrambling device Client that disguises oneself as sends bag RST bag to Server, and simultaneously internet service group (Internet Service Group, referred to as ISG) pretends Server and gives out a contract for a project to Client.Make link chain rupture, reached by the barrier effect of control flow check.
The third method: send SYN bag method.Namely paralleling model P2P scrambling device disguises oneself as Client, by sending the SYN bag being positioned at window to Server, makes link chain rupture, to reach by the barrier effect of control flow check.
(2) flow control method
Can be the combination of following two kinds of methods to the Flow Control of P2P data flow, paralleling model P2P scrambling system can be switched to other method when a kind of method of discovery is invalid carries out Flow Control again.
First method: amendment transmission control protocol (Transmission Control Protocol, referred to as TCP) sliding window method
The method is the speed utilizing the receive window size of data receiver notification data recipient to carry out control data transmission.
Second method: tcp window dislocation method
Fig. 5 is the schematic diagram of tcp window dislocation method according to the preferred embodiment of the invention, as shown in Figure 5, the particular content of this tcp window dislocation method is as follows: the paralleling model P2P scrambling system client (Client) that disguises oneself as sends legal ACK fast to server (Server) and wraps, Server is made to send packet (Data) to Client as soon as possible, when packet exceeds the window of Client, packet can be abandoned by Client.When the message amount be dropped is abundant, the receive window of Client and the send window of Server can misplace completely.Client issues Server ACK bag when processing the packet in buffer memory can be thought the ACK bag (paralleling model P2P scrambling device pretended Client distribute ACK wrapped) of repetition by Server, so Server can not comprehend the ACK bag of Client.When window misalignment is enough large, Client processes the ACK bag that the bag in all buffer memorys sends and is thought that the ACK of repetition wraps by Server, so Server can not repeat to send the bag that abandoned by Client to Client.At this moment the ISG Server that disguises oneself as again sends the bag abandoned by Client to Client, and the Client that simultaneously disguises oneself as sends ACK to Server and asks for new packet.Such paralleling model P2P scrambling device just controls the transmitting-receiving speed packet of whole link.In the process of paralleling model P2P scrambling system control link, two identical ACK bags can be received, so Fast retransmission can not be caused at different time for each packet Server.
Preferred embodiment 4
This preferred embodiment is based on to User Datagram Protoco (UDP) (User Datagram Protocol, referred to as UDP) blocking-up of the P2P of agreement and Flow Control, content is as follows: obtain network data flow, the message corresponding to this network data flow carries out udp protocol identification, determine the P2P data flow of udp protocol, disturb bag to P2P data flow icmp, scrambler is carried out to this P2P data flow.Disturbing bag to make port unreachable by sending icmp, reaching by the blocking-up of control flow check and fluid control effect.
