研究了BPEL4WS执行引擎WebJetFlow对Web服务的异步调用机制,在引擎的服务调用代理中对Web服务统一采用非阻塞双传输异步调用,提高了调用线程的利用率.同时引入了cache机制并设计了相应的cache替换算法,保证了引擎对异步调用结果消息的匹配效率以及数据安全性,通过实验验证引擎的性能有了明显的提高.
研究瞭BPEL4WS執行引擎WebJetFlow對Web服務的異步調用機製,在引擎的服務調用代理中對Web服務統一採用非阻塞雙傳輸異步調用,提高瞭調用線程的利用率.同時引入瞭cache機製併設計瞭相應的cache替換算法,保證瞭引擎對異步調用結果消息的匹配效率以及數據安全性,通過實驗驗證引擎的性能有瞭明顯的提高.

This paper studied the Web services asynchronous invocation mechanism of the BPEL4WS engine WebJetFlow.It used the non-blocking-dual-channel asynchronous invocation to invoke the Web services in the service invocation proxy of the engine in order to improve the utilization ratio of the invocation threads.Also it imported the cache mechanism and designed an algorithm for cache substitution,thus it ensured the efficiency in matching the asynchronous results and data security.Finally,the experiment results demonstrate that the performance of the engine has been improved obviously.
