please explain me this also:

how c= odel controls the delay like it drops the packet when it spends more time t= han target and after that it will be retransmitted.
So in case of= retransmission and all, i think delay should be more. isn't it?

Next , How =C2=A0does UDP react lik= e tcp adjusts its rate when there is packet loss and UDP?

More packet loss is no necessarily a bad thing.
You need to measure throughput and latency together.
