What is the network address of 172.16.66.99/20

A network switch is dropping packets because its buffer is full. If the buffer can hold 1000 packets, and the packet arrival rate is 1500 packets per second, what is the packet loss rate?

If the transmission time for a packet is 5 milliseconds and the propagation delay is 2 milliseconds, what is the total delay experienced by the packet?

Consider sending an IP datagram of size 1420 bytes (including 20 bytes of IP header)

from a sender to a receiver over a path of two links with a router between them. The first

link (sender to router) has an MTU (Maximum Transmission Unit) size of 542 bytes,

while the second link (router to receiver) has an MTU size of 360 bytes. The number of

fragments that would be delivered at the receiver is

AIMD based communication starts in slow start phase. The threshold is 32 MSS.  If timeout occurs at 6th transmission, what will be the new threshold after timeout? 

An IP datagram of size 4000 bytes (including 20-byte header) is to be sent over a network with MTU = 1500 bytes. How many fragments will be created?

The transmission delay is 1 msec and propagation delay is 49.5 msec. what should be minimum senders window size so that the utilization is 10% ? Go Back-N is used.

What is the network address for the host 192.168.45.67/20?

Consider sending a large file using TCP over a connection

with no loss. Assuming we start with slow start phase and threshold is 8 MSS, how

many RTTs would it take to increase to 12 MSS using AIMD?
