Abstract: To reduce communication cost in data service calling process,the response acceleration of data services based on caching and compression was proposed.The message template was used to extract meaningful objects of Simple Object Access Protocol(SOAP),thus the time overhead of eXtensible Markup Language(XML)was reduced.Through objects of caching application layer,the time overhead of service execution was decreased,and network transmission time was also decreased by XMill compression algorithm.Moreover,the caching consistency was preserved to enhance the benefits.Extensive experiments based on Spring-WS-Test benchmark demonstrated that when the cache hit reached 10%,the response acceleration reduced 74% response latency and improved 67% throughput comparing to non-caching techniques.

Key words: data service, simple object access protocol, differential processing, caching consistency
