a) Assume you have a link that has 50ms of round-trip-time, the transmission rate is 3Mbits/sec, and each packet is 1Kbyte. If we are using the concurrent logical channels protocol, how many logical channels do we need to maintain 100% throughput (assuming no message loss)

b) Assume three of the above (i.e. part (a)) logical channels have lost a message and are stuck waiting for the timeout to occur (assume the timeout value unnecessarily large, way too big). How much is the reduction in throughput?
