Embodiment Construction

[0034] The method for ensuring reliable transmission of data exchange provided by the present invention is mainly applied to a data exchange system in a data exchange platform. The invention controls the process of data exchange by adopting technologies such as end-to-end data transmission, message confirmation, flow control, fault recovery and data priority control, ensures the reliability of data exchange, and supports reliable transmission of data exchange on a data exchange platform. Below we introduce these five aspects in turn:

[0035] 1. End-to-end data transmission:

[0036] The data exchange reliable transmission method proposed by the present invention stipulates that data transmission is carried out according to an end-to-end transmission mode. The so-called end-to-end data transmission means that the data exchange process is only performed by the two parties performing the data exchange, and the intermediate nodes passed through during the exchange process are on...

Abstract

The invention discloses a data exchanging and reliable transmitting method for implementing reliable data transmission of a data exchange system, screening influence of intermediate nodes on data transmission by end-to-end data transmitting method, and improving data exchange reliability; it implements a complete flow of message transmission by defining a perfect message confirm mechanism; implements flow control of the data exchange system by adopting data fragments and transaction queues, preventing abnormity of data-exchanging nodes caused by processing ability and network conditions and raising system reliability and processing efficiency of system; implements system failure removal by permanence of transaction information, improving fault tolerance of system and further providing a foundation for implementing breakpoint and sustained transmission; makes priority division on transaction queues, assuring importer applications can be processed firstly, better adapted to government affairs data exchange requirements.

Description

technical field [0001] The invention relates to a method for ensuring reliable transmission of data exchange in a data exchange system. Background technique [0002] The e-government data exchange platform provides support for data exchange between different systems and different data sources. The data exchange system in the data exchange platform mainly completes the control of the specific data exchange process, which allows each legal user to share their The data packets to be transmitted are safely and reliably transmitted to the designated place to solve the problems of data uploading, downloading and comprehensive utilization. When the data exchange system completes the data exchange, there may be system crashes, network failures, abnormal software components, etc., in order to make the data exchange system can still complete the data transmission reliably in the case of abnormalities, usually, the data exchange system Reliable transmission technology should be adopte...
