Research On The Web Service Data Transmission Technology

With the development of the Internet，Web Service technology which is based onthe architecture of SOA has a wide range of increasingly widespread use, but in thefield of Web Service data transmission there is still significantly very difficult to breakthe transmission bottlenecks. In order to alleviate the Web Service data transmissionbottleneck different research programs have proposed many solutions, but allsolutions have their own defects. So studying and improving the Web Service datatransmission technology has great practical significance for the development of theWeb Service.In principle, the integrated system built by Web Service technology uses SOAPmessages which are based on XML and transmitted by HTTP to communicate withothers. XML, SOAP, HTTP determine all the advantages of the Web Service, and theirrespective limitations also brought a Web Service all the disadvantages. This articleexplores in detail the root causes of the low efficiency in Web Service datatransmission--the redundancy of information in the XML language, the inefficiency inXML parsing and the simplicity and statelessness in HTTP. Then it tells the fieldswhere Web Service is less applicable.In order to really improve the data transmission efficiency of Web Service, thispaper proposes to break the bottleneck of the Web Service data transmission by usingthe Web Socket service. It changes the traditional transmission way of single-line tothe transmission way of two-line (using the HTTP transfer the key messages, and thenuse Web Socket to transfer specific data). This proposal greatly reduces the cost oftime for XML-file packaging and CPU resources and help Web Service easily get ridof the HTTP protocol data transfer restrictions. Because Web Socket is anInternet-based public open standard, the combination of Web Service and Web Socket service does not undermines the openness and compatibility of Web Service in thearea of network integration, but extends the field of use of the Web Service.In order to test the effectiveness of the program which uses Web Socket service inWeb Service data transmission, this article build an experimental environment.Ittested different parameters including data transfer time, CPU resources occupancyrate and some other characteristic parameters in there designed program includingtraditional transfer program, the new transfer program using Web Socket service andthe chunked transfer program. The experimental results show that the new programshows a good performance and is a good Web Service data transmission program.
