Hey Brett,

Quick glance makes me believe the S and D nodes are equal bandwidth,
but only R1-R2 bandwidth is explicitly stated.S1, D1, Sn, Dn are only
ever mentioned in the topology. If Sender is same or lower rate than
Destination, then we really shouldn't need almost any buffering.
Issue should only come when Sender is significantly higher rate than
Destination and network is not limiting them.
