Dear David and Fred,
A small buffer offers small delay to delay-sensitive traffic.
Throughput-greedy traffic is served through another, bigger buffer
at a higher per-flow rate. The two-buffer forwarding gives
the senders complete freedom in choosing between
the two best-effort services of larger throughput versus
low queuing delay:

The architecture is an attempt at throughput-delay differentiation
designed explicitly for incremental deployment in the multi-provider
