Communication method avoiding p2p traffic identification

Abstract

The invention discloses a communication method avoiding p2p traffic identification. The method comprises the following steps: S20: serializing information to be sent; S40: splitting the serialized information into a plurality of data packets with random lengths; S60: adding random data with preset lengths at the heads and / or tails of the data packets; and S80: sending the plurality of data packets in a random sequence through a dynamic network port. According to the communication method disclosed by the invention, the means of serializing the information to binary, splitting the data, randomly setting the lengths of the data packets, filling random data in important identification areas, sending the data packets in the random sequence and sending the data packets through the dynamic port and the like are integrated to effectively avoid the identification of the existing p2p traffic identification means and realize speed limitation or interception, and no single module needs to be set to establish an additional communication channel; such means as encrypting the data packets and adding random disturbing data packets and the like are further integrated to reduce the identification rate; and the instruction and the data are divided into double-channel communication to further reduce the identification rate.

Description

technical field [0001] The present application relates to the technical field of peer-to-peer network communication, in particular to a communication method for avoiding p2p traffic identification. Background technique [0002] After the emergence of p2p (Peer to Peer, peer-to-peer network, referred to as p2p) technology, the network grid computing mode has shifted from centralized to distributed, and the core of network applications has spread from central servers to edge devices. Due to the increase of p2p traffic on the current network, operators, enterprise users, and users in education and other industries all impose restrictions on such traffic, and at the same time set up, manage and control p2p traffic through firewalls and network management equipment. [0003] At present, the main equipment for identifying p2p traffic includes firewalls, routers, application gateways, and bypass statistics systems. The main means of identification are as follows: [0004] 1. Port...

Problems solved by technology

On the one hand, both VPN and SSL communication methods require additional channels to be established, and modules need to be set up separately for deployment

On the other hand, the two communication methods of VPN and SSL only camouflage the data content in the means of evading identification, and do not carry out targeted evasion from various aspects. For example, the two communication methods of VPN and SSL have some characteristics that are easy to be identified. or was misidentified as a characteristic of other intercepted communication protocols, resulting in blocking due to identification or misidentification
