Problems solved by technology

However, in MPT, the message sent by the end host needs to pass through the three new logical layers and be encapsulated multiple times, which will undoubtedly increase the transmission delay and reduce the application throughput.

Abstract

The invention discloses a transmission layer multipath communication method and system, and the method comprises the steps: an MPTUP layer is deployed between an application layer and a transmission layer of a network protocol; Initiating a connection between the connection initiator and the connection receiver in a first preset mode, Wherein the connection initiator and the connection receiver carry out data communication through TCP connection, and when the connection initiator and the connection receiver both support MPTUP transmission layer multi-path transmission, data are sent and received by establishing a UDP sub-stream; the connection initiator or the connection receiver can disconnect the UDP sub-streams; And the connection initiator or the connection receiver stops the multi-path transmission of the MPTUP transmission layer and ends the data communication in a second preset mode. The method supports multi-path transmission, network bandwidth resources are fully utilized, network link load balancing is achieved, and standard TCP can be used for communication when an end host does not support MPTUP.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to a transmission layer multipath communication method and system. Background technique [0002] Multi-path transmission technology can effectively utilize network bandwidth resources, realize network link load balancing, and improve the robustness of network transmission. The MultiPath Transmission Control Protocol (MPTCP for short) is one of the most widely used and most concerned multipath communication methods. The Internet Engineering Task Force (IETF for short) proposed the Transmission Control Protocol (TCP for short) extension MPTCP that supports multipath operation in the RTF 6824 "TCP Extensions for Multipath Operation with Multiple Addresses" document, Used to support multipath communication at the transport layer. In this method, the end host deploys an MPTCP layer between the transport layer and the network layer to support multi-path communication at the tr...
