Consumers or administrators of small business networks usually cannot directly configure the link which connects their network to their Internet provider. The link setup often provides a sub-optimal configuration for end users' traffic patterns and, at best, favors bulk transfers. We introduce a method of imposing desired active queue management behavior on an upstream queue without requiring administrative control over the queue. We achieve this by observing various externally measurable characteristics of the queue's behavior and then manipulating congestion-controlled traffic through standard feedback channels such as packet drops or ECN notifications. This technique can be directly applied to improve the quality of VoIP connections sharing a bottleneck link with multiple TCP connections. Our approach performs comparably to a RED policy applied on the remote queue, without dropping VoIP packets. The complexity of our approach is independent of the number of connections, and hence it can be implemented on a network gateway without adding noticeable processing overhead.
