We believe that this future vision will need to rely on a three- tier infrastructure consisting of back-end servers, infrastructure servers, and front-end clients (mobile or static, handheld or embedded). The critical question for future systems will be how to deliver services on-demand from back-end servers to resource- constrained clients. If we can handle the new requirements of these systems, we can enable this computing infrastructure to offer significantly more services to users in a more pervasive way.
This talk will present two main Psi subprojects: "services-on-demand" and "adaptive offloaded services". It will outline the high level architecture, present some preliminary performance measurements, and compare the project to related work in academia and industry.
