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. The method includes: A. in an idle state, a proxy server communicates with each node of the system at regular intervals; When a node, the SCTP-CMT client establishes a sub-flow communication connection with each node of the system through a proxy server; after C, the sub-flow communication connection is established, the SCTP-CMT client communicates with each node of the system through the sub-flow communication connection ; D. When it is no longer necessary to access each node of the system, the SCTP‑CMT client closes the subflow communication connection with each node of the system through the proxy server. The technical scheme of the invention can fully utilize the bandwidth of each node in the distributed system to upload and download data, save connection time, accelerate data access speed and transmission efficiency, and promote the development of distributed systems and cloud computing technologies.

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...
