Problems solved by technology

MPTCP can establish multiple TCP sub-flows for communication, but the establishment of each TCP sub-flow requires a handshake between the addresses of both parties, which will cause a lot of delay when the communication is frequent, and is not conducive to the realization of user-oriented virtualization in distributed systems

Abstract

The invention discloses a distributed system parallel access method and system based on SCTP-CMT (Stream Control Transmission Protocol-Concurrent Multipath Transfer). The method comprises the following steps that: A, in an idle state, message communication between a proxy server and each node of the system is performed periodically; B, when each node of the system needs to be accessed, an SCTP-CMT client establishes sub-stream communication connection with each node of the system through the proxy server; C, the SCTP-CMT client performs communication with each node of the system the sub-stream communication connection after establishment of the sub-stream communication connection; and D, when each node of the system does not need to be accessed, the SCTP-CMT client turns off the sub-stream communication connection with each node of the system through the proxy server. According to the technical scheme, the bandwidth of each node in a distributed system can be utilized fully to upload and download data, so that the connection time is saved; the data access speed and transmission efficiency can be increased; and the development of a distributed system and a cloud computation technology is facilitated.

Description

technical field [0001] The present invention relates to the technical field of distributed data processing, in particular to a distributed system parallel access method and system based on SCTP-CMT. Background technique [0002] Distributed data processing is the basis for realizing cloud computing and big data technology. At present, distributed storage systems such as DAS (Direct-Attached Storage, DAS for short, open system direct-attached storage), SAN (Storage AreaNetwork, SAN for short), object storage and distributed file systems, etc., generally Provide users with a network interface for data access. Users access different nodes of the distributed system through TCP (Transmission Control Protocol, Transmission Control Protocol) or UDP (UDP is the abbreviation of User Datagram Protocol, and the Chinese name is User Datagram Protocol). Communicate with different nodes respectively. [0003] If the data is distributed in different nodes, currently users can only access...
