How can the tail drop algorithm support traffic shaping when the queue is filled?
A.
It drops older TCP packets that are set to be redelivered due to errors on the
link until the queue has room for more traffic,
B.
It drops older packets with a size of 64 bytes or more until the queue has room
for more traffic,
C.
It drops new packets with a size of less than 64 bytes until the queue has room
for more traffic.
D.
It drops all new packets until the queue has room for more traffic.

Tail Drop, or Drop Tail, is a very simple queue management algorithm used by Internet
routers, e.g. in the network schedulers, and network switches to decide when to drop
packets. In contrast to the more complex algorithms like RED and WRED, in Tail Drop the
traffic is not differentiated. Each packet is treated identically. With tail drop, when the
queue is filled to its maximum capacity, the newly arriving packets are dropped until the
queue has enough room to accept incoming traffic.
