A Comparison of Data Exchange Mechanisms for Real-Time Communication

While web applications continue to employ traditional client-server model, most of the current applications demand real time bi-directional communication. In such setups, data exchanges between both the parties (client and server) are very frequent. Thus, performance of the network is subject to various factors decided by the choice of data exchange mechanism. This shows that the choice of data exchange mechanism is vital to performance of a web-application employing it. This paper compares various data exchange mechanisms with respect to factors affecting real time web applications. While the absolute values of benchmarking may vary with the systems, the relative difference between them can be used as a reference for selecting a mechanism for an application. Hence, this paper can be used as a reference to choose appropriate data exchange mechanism for the concerned application.
