Effective load-balancing systems for services hosted in un- structured networks need to take into account both the congestion of the network and the load on the servers. In this whitepaper, we propose a comprehensive load-balancing solution that works well for such networks. The system we propose, called Aster*x, tries to minimize response time by controlling the load on the network and the servers using customized flow routing. We hope to use the GENI infrastructure to understand how Aster*x works within a combined network and computation slice spanning multiple campuses across the country; the GENI infrastructure is well-suited for this purpose be- cause of the distributed and realistic nature of the computing and networking substrate. Besides the base behavior, we plan to investigate the effect of dynamically adding and removing computing resources to the system, increasing the request arrival rate, altering the CPU or network load of each request, and changing load-balancing algorithms.
