Problems solved by technology

[0015] In terms of disadvantages: Simple Object Access Protocol is based on XML, and it takes a lot of time to generate and parse messages. Especially for a large amount of data, it is not feasible to use Simple Object Access Protocol to transmit data. In addition, the protocol is not suitable for complex data types and objects. The transmission support is not good; the use of the file transfer protocol needs to save the data into a file before transferring, which is time-consuming and laborious for small data; the grid file transfer protocol also needs to transfer the data to the external storage before transferring, and the protocol is more complicated , the security and authentication overhead is large, and it is not very convenient for users to use

Embodiment Construction

[0039] The present invention realizes by following technical method:

[0040] The data transmission method described in the present invention includes two aspects of hardware and software. The hardware includes: servers providing services, data servers and networks, and the software includes: operating systems running on servers providing services, SOA system underlying software infrastructure, services running on infrastructure, data transmission optimization adapters; running on data Server-side support software on the server.

[0041] The servers that provide the service are connected by a network. In the process of data transmission, if a file transfer protocol or grid file transfer protocol is used, which requires data transfer through external storage, a data server needs to be introduced. The role of the data server is to transfer data between services. The server providing the service and the data server are also connected through the network. Data servers sometime...

Abstract

The invention relates to a data transmission technique between services in facing-service system, wherein it adds one data transmission optimize adaptor in the providing server; for the data transmission request with data and target service addresses that transmitted form local server, evaluating the conditions as data transmission amount, sending test pack to the providing server with target service or the data server of protocol network, to test; then obtaining bandwidth and delay information to select relative transmission protocol. The invention can transmit object access protocol, document transmit protocol, and mesh document transmission protocol on special platform, to improve flexibility.

Description

technical field [0001] The invention is a data transmission method between services under a service-oriented architecture environment, in particular a dynamic self-adaptive optimization data transmission method for Web services, grid services and other services. Background technique [0002] Service-Oriented Architecture (SOA) is a coarse-grained, loosely coupled software architecture. Under the service-oriented architecture, all elements in the environment are abstracted as services, and services communicate through interfaces defined based on standards. However, a single service cannot complete complex tasks, so we need multiple services to perform a task collaboratively. In this process, how to handle communication and data transmission between services becomes a key issue. [0003] At present, in the service-oriented architecture environment, the data transmission method between services usually only supports a single protocol, such as Simple Object Access Protocol (SOA...
