There is no differentiated drop mechanism. Higher priority traffic is dropped in the same way as best-effort traffic. E . In TCP starvation， traffic exceeds the queue limit because of the bursty nature of packet networks. A router cannot handle multiple concurrent TCP sessions. F . Global synchronization occurs because multiple TCP hosts reduce their transmission rates at random intervals in response to packet dropping
