Tcp Start-up Behavior under the proportional Fair Scheduling Policy

It is expected that the proportional fair (PF) scheduler will be used widely incdma2000 1xEV-DO systems because it maximizes the sum of each user’s utility,which is given by the logarithm of its average throughput. However, in terms ofshort-term average throughput, PF scheduler may lead to a large RTT variation.We analyze the impact of PF scheduler on TCP start-up behavior through NS-2simulation. To show the impact of PF scheduling on TCP, we also analyze thepacket transmission delay under the PF scheduling policy through mathematicalmodel.
