WSDL-Driven SOAP Compression
Christian H. Werner, Carsten Buschmann, Stefan Fischer · International Journal of Web Services Research · 2005
A major drawback of using SOAP for application integration is its enormous demand for network bandwidth. Compared to classical approaches like JavaRMI and Corba, SOAP messages typically cause more than three times more network traffic. In this paper we will explore compression strategies and give a detailed survey and evaluation of state-of-the-art binary encoding techniques for SOAP. We also introduce a new experimental concept for SOAP compression based on differential encoding, which makes use of the commonly available WSDL description of a SOAP Web service. We do not only conduct a detailed evaluation of compression effectiveness but also provide the results of execution time measurements.
