    What are three problems with the tail drop mechanism of managing interface congestion？（）
    A

    Queuing introduces equal delays for packets of the same flow， resulting in jitter.

    B

    When congestion occurs， dropping affects most of the TCP sessions， which simultaneously back off and then restart again.

    C

    All buffers can temporarily be seized by aggressive flows， and normal TCP flows experience buffer starvation.

    D

    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

    Traditional network layer packet forwarding relies on the information provided by network layer （） protocols, or static routing, to make an independent （本题）decision at each hop within the network. The forwarding （）is based solely on the destination （）IP address. All packets for the same destination follow the same path across the network if no other equal-cost paths exist. Whenever a router has two equal-cost （）toward a destination, the packets toward the destination might take one or both of them, resulting in some degree of load sharing.
