Question

Calculate the total time required to transfer a 1.5-MB file in the following cases, assuming an RTT of 80 ms, a packet size of 1 KBdata, and an initial 2 RTT handshake before data is sent:

The bandwidth is 10 Mbps, and data packets can be sent continuously.
The bandwidth is 10 Mbps, but after we finish sending eachdata packet we must wait one RTT before sending the next.

Expert Solution

Step 1

Given data:-

File size = 1.5MB
RTT = 80ms
packet size = 1KB

Handshaking time = 2xRTT = 2x80 = 160ms
total number of packets = 1.5MB/1KB = 1500 packets
