CAS: A SIP-based proxy for the provisioning of HTTP session mobility

On one hand, the convergence of the Internet, Telecommunication and Broadcasting is generating new services over the Internet, and on the other hand, the online experience is getting improved via the introduction of user profile mobility and web session mobility. While different architectural schemes for HTTP session mobility have been proposed and implemented in the academia, the industry has introduced user profile mobility solutions, such as Mozilla Weave and Google Browser Sync. This paper presents our effort to improve the web browsing experience via a SIP-based web session mobility service. It discusses the client and proxy features of our session mobility system. The system architecture is service-oriented and easy to integrate in any existing SIP-based deployment environment. Experimental results about CPU usage, memory consumption, and number of requests processed at the proxy side confirm the feasibility of our solution from a service provider perspective in all most common Internet deployment scenarios.
