than others, but without quantifying the differentiation. Recently, research studies have
tried to strengthen the guarantees of relative per-class QoS, and have proposed new
buffer management and scheduling algorithms which can support stronger notions of
relative QoS [6, 7, 15, 16]. Probably the best known such effort is the proportional service
differentiation model [6, 7], which attempts to enforce that the ratios of delays or
loss rates of successive priority classes be roughly constant. For two priority classes
such a service could specify that the delays of packets from the higher-priority class be
half of the delays from the lower-priority class, but without specifying an upper bound
on the delays.
