摘    要:为了能够避免或减少数据传输量的Web服务新模式,提出一种利用程序代码迁移代替数据迁移的Web服务新模型——基于代码迁移的Web服务(CTWS)。同时通过扩展OGC WPS规范、建立代码迁移技术实现体系,将CTWS应用于WPS服务,提出基于代码迁移的WPS(CTWPS)模型和技术方法。最后通过实践,对相关理论和技术进行了验证,比较CTWPS与OGC WPS服务在数据传输量和调用效率之间的优劣。研究结果表明:CTWPS相对于现有OGC WPS具有数据传输量小、调用效率和可靠性高的优点,CTWS具有广泛的应用价值。

Abstract: Aimed at avoiding or reducing the amount of data transmission, a new model of web service was proposed based on code transmission (CTWS) using program code transmission replace data transmission. Then the application of CTWS in WPS was discussed and a model of WPS was proposed based on code transmission (CTWPS) via expanding OGC WPS standards, and establishing new technology system. At last, an experimental system was developed to test the data transmission amount and the executing efficiency of OGC WPS and CTWPS models. The test results show that CTWPS has obvious advantages of little data transmission amount, high executing efficiency and high reliability, and CTWS has large potential application value in web service technology.
