To make cloud computing work, we must make applications run substantially faster, both over the Internet and within data centers. Our measurements of real applications show that today's protocols fall short, leading to slow page-load times across the Internet
and congestion collapses inside the data center. We have developed a new suite of architectures and protocols that boost performance and the robustness of communications to overcome these problems. The results are backed by real measurements and a new theory
describing protocol dynamics that enables us to remedy fundamental problems in the Transmission Control Protocol. We will demo the experience users will have with Bing Web sites, both with and without our improvements. The difference is stunning. We also will
show visualizations of intra-data-center communication problems and our changes that fix them. This work stems from collaborations with Bing and Windows Core Operating System Networking.
