Main stream connection building method and device based on MPTCP (Multi-Path Transmission Control Protocol)

Abstract

The embodiment of the invention provides a main stream connection building method and device based on an MPTCP. A receiving end receives an authentication request which carries identity authentication information and is sent by a sending end based on an application layer secure connection; after verifying that the sending end is legal according to the identity authentication information, allocating and storing identity identification information and a first authentication parameter for the sending end; receiving a synchronous SYN (Synchronous) message which carries the identity identification information and a first session key and is sent by the sending end; searching the first authentication parameter corresponding to the identity identification information carried in the SYN message; using the first authentication parameter to encrypt through an encryption algorithm so as to obtain a second session key; when the first session key matches with the second session key, sending a synchronous acknowledgement SYN+ACK (Synchronous + Acknowledgement) message to the sending end; and after receiving the acknowledgement ACK message of the sending end, building a main stream connection with the sending end. Through the embodiment of the invention, the problem that the receiving end is overload is avoided; and the performance of the receiving end is improved.

Description

technical field [0001] The embodiment of the present invention relates to the field of communication technology, and in particular to a method and device for establishing a mainstream connection based on MPTCP (MultiPathTransmissionControlProtocol, multipath transmission control protocol). Background technique [0002] MPTCP (MultiPathTransmissionControlProtocol, MultiPath Transmission Control Protocol) is a transport layer protocol that uses multiple paths to achieve concurrent transmission, which can improve end-to-end throughput and increase network utilization. [0003] MPTCP-based connections include masterflow connections (MasterFlow) and subflow connections (SubFlow). The masterflow connection refers to the first connection established by both parties, and the connections established after the first connection are all subflow connections. [0004] In the prior art, the connection based on MPTCP is similar to the connection based on the traditional TCP (Transmission Co...
