Setting PDD parameter (3)

• We used a conservative RTT estimation . Actual RTT is larger for at least propagation and transmission delay on the link.

• Hence, we overestimated the influence of the delay differentiation on RTT and TCP throughput.

• Even setting to:

provides higher throughput for TS flows than in best-effort network.

• This property makes TS class attractive for throughput- sensitive applications.
