Application Specific Communication Stack for Computationally Intensive Market Research Internet Information System

摘要

A robust and reliable transactional processing is a key quality factor in computationally intensive, multilayer information systems. We give three design patterns that model reliable session and transaction management in transactional web applications . These are: session timeout, server default action and split client-server state representation. Only the first design pattern can be successfully implemented with the standard WCF [1] facilities, thus we also include our optimized communication stack. The presented method significantly improves the operational capabilities of the state-of-the-art WCF [1] in respect of robustness (reliable finalization), flow control flexibility (synchronous, asynchronous) and efficiency (a significant performance boost).
