Consider the following two causes of 1-second network delay (assume ACKs
return instantaneously):
i) One intermediate router with a 1-second outbound per-packet bandwidth
delay and no competing traffic.
ii) One intermediate router with a 100-ms outbound per-packet bandwidth
delay and with a steadily replenished (from another source) 10 packets in the
queue.
(a) How might a transport protocol in general distinguish between these two
cases
(b) Suppose TCP Vegas sends over the above connections, with an initial
Congestion Window of 3 packets.
What will happen to Congestion Window in each
case?
Assume BaseRTT = 1 second and ??is 1 packet per second
