This paper proposes Application Networking (App.Net) architecture that allows Web server deploying intermediate response with associated partial workflow logic to middle proxies. The recipient proxy is allowed to instantiate the workflow using local services or download remote application modules. The final response is the output from the workflow fed with the intermediate response entity. In this paper, we define a workflow modulation method to organize service workflow and manipulate them in uniform operations. Furthermore, we developed one App.Net simulator to measure the performance of sample applications existed in the Web under different deployment methods and delivery environments. Our simulation results show that using workflow and dynamic application deployment, App.Net can achieve better performance than conventional methods.
