Plug-n-Serve: Load-Balancing Web Traffic using OpenFlow

Effective load-balancing systems for services hosted in un-structured networks need to take into account both the con-gestion of the network and the load on the servers. In this demonstration, we illustrate a comprehensive load-balancing solution that works well for such networks. The system we showcase, called Plug-n-Serve, tries to minimize response time by controlling the load on the network and the servers using customized flow routing. The demonstration shows how the Plug-n-Serve system works within our deployment in the CS building at Stanford University. Besides the base behavior, we show 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
