Optimizing Web Service Messaging Performance Using a Context Store for Static Data

The performance and efficiency of Web Service messaging can be greatly increased by removing the redundant parts of SOAP messages. This paper describes our research work in optimizing SOAP message contents. This area is particularly important to those applications that are physically constrained mobile computing environments. The redundant or static parts of the SOAP message may be treated as metadata and stored in shared metadata space. We integrate our optimized SOAP messaging system with our information management research framework. We evaluate our approach by testing the performance of the resulting system. The empirical result shows that we save on average 83% of message size and on average 41% of transit time.
