Suppose we have the following record of packet transmission times between a sender (S) and recipient (R) for a given day: 9:00 a.m. S to R 10 seconds, R to S 10 seconds 9:01 a.m. S to R 11 seconds, R to S 9 seconds 9:02 a.m. S to R 8 seconds, R to S 14 seconds 9:03 a.m. S to R 12 seconds, R to S 6 seconds 10:00 a.m. S to R 20 seconds, R to S 20 seconds 10:01 a.m. S to R 22 seconds, R to S 18 seconds 10:02 a.m. S to R 16 seconds, R to S 28 seconds 10:03 a.m. S to R 24 seconds, R to S 12 seconds At 10:04:00 we send a packet. Assuming adaptive retransmission, what is the most appropriate amount of time to wait without receiving an acknowledgement from the would-be recipient, before resending the packet?
