This paper presents a new architecture that enables a set of clients to enforce traffic shaping policies among them through the delegation of congestion signals. When congestion-aware Internet flows share a bottleneck link, the users compete for bandwidth and must respond to congestion signals promptly by decreasing their throughput. For clients running real-time applications (e.g., gaming, streaming), this may impose strict limitation on their achievable throughput over short time-scales. This gives the Free connection just enough freedom to meet specific throughput requirements as requested by the application running on top, without affecting the level of congestion in the network.
