N-to-1 SOAP Requests Bundling for Efficient Software Service Delivery

One key factor towards the success of software and service is the standardization of service protocols/languages and the interoperability among them. While SOAP (Simple Object Access Protocol) is one such protocol for service message, its heavy performance overhead is often a big concern, as compared to the light-weighted REST (Representational State Transfer) and HTTP protocols. In this paper, we propose an innovative SOAP requests bundling mechanism to amortize service innovation overhead. This is done by performing serialization and de-serialization on one SOAP message for multiple requests. Details of this bundling mechanism, together with its supporting architecture are given. Our experimental results on TPCW show that the system throughput can be improved significantly, in the order of about 50% to about a few hundred percents.
