Queues allow network operators to control traffic: where queues build, they can enforce scheduling and shaping policies. In the Internet today, however, there is a mismatch between where queues build and where control is most effectively enforced; queues build at bottleneck links that are often not under the control of the data sender. To resolve this mismatch, we propose a new kind of middlebox, called Bundler, which moves queues away from uncontrollable network locations to edge devices. This talk will describe how the use of signal processing methods in congestion control, combined with Linux tricks, can enable an effective and scalable site-to-site traffic controller using Bundler. I will also describe some recent work in using verification methods to improve congestion control robustness.
