We present the design, implementation, and performance evaluation of AMPS -a flexible, scalable proxy testbed that supports a wide and extensible set of next-generation proxy streaming services. AMPS employs a modular architecture and is built on top of a commodity Linux system. We quantify the maximum achievable throughput for two of the principal components of the proxy -the control plane and data plane, and identify the CPU to be the system bottleneck. Through profiling studies, we further

We also characterize the end-to-end performance along the server-to-proxy-to-client path. We discuss lessons learned and the various optimizations made in the course of our study to improve system performance.
