Concurrent processing of web service for crop model based on caching mechanism

In order to improve the responding time of web services for crop model, the concurrent processing scenario of web services for crop model was proposed in this paper. By analyzing the combination structure of web services for crop model, communication features of data web services and responding time feature of web services for crop model, the concurrent processing scenario of web services for crop model was designed based on multi-thread processing and data caching technology. Taking web services of crop management knowledge model as the testing target, the effectiveness of concurrent processing scenario was verified in a real network environment. The results showed that the responding time of web service for crop model with concurrent processing scenario reduced 32% and 35% for single-user at multi-location and multi-user at multi-location, respectively, which improved the model ability for multi-user concurrent processing. These results provide the technical support for regional application of crop model.
