(This problem is based on P25 in Chapter 1 of the Kurose and Ross textbook.) There is an important measurement of network capacity called the Bandwidth Delay Product (BDP). This product is a measurement of how many bits can fill up a network link. It gives the maximum amount of data that can be transmitted by the sender at a given time before waiting for acknowledgment. BDP = bandwidth (bits per sec) * round trip time (in seconds) Calculate the BDP for the scenario where two hosts, A and B, are separated by 20,000 km and are connected by a direct link of R = 2 Mbps. Assume the propagation speed over the link is 2.5 x 108 m/sec. (Remember to use the round trip time (RTT) in your calculation.) 320,000 bits 120,000 bits O 1,600,000 bits 80,000 bits
