  1. Calculate the total time required to transfer a 1.5MB (Mbytes) file in the following cases, assuming a Round Trip Time (RTT) of 80ms (milliseconds), a packet size of 1KB (Kbyte) data, and an initial 2xRTT of “handshaking” before data is sent:
  1. The bandwidth is 10 Mbps (Megabits/sec), and data packets can be sent continuously.
  2. The bandwidth is 10 Mbps, but after we finish sending each data packet, we must wait one RTT before sending the next packet.

(Remember RTT is up-and-down delay (two-way delay) = 2 x Propagation Delay) (10 points)

    Using python 3 to create the UDP Ping Clien and server. Using UDP sockets, you will write a client and server program that enables the client to determine the round-trip time (RTT) to the server. To determine the RTT delay, the client records the time on sending a ping request to the server, and then records the time on receiving a ping response from the server. The difference in the two times is the RTT. The ping message contains 2...
