b) TCP Tahoe with Fast Retransmission is used to control congestion. The maximum segment size is equal to 4 KB. Initially, the threshold is set to 64 KB and the TCP congestion window is equal to 32 KB but a timeout has occurred. i) After how many consecutive successful transmission bursts will Additive Increase start? After the start of Additive Increase, there were six consecutive successful transmission bursts before three duplicate acknowledgments were received. What are now the values of the congestion window and the threshold? c) The TCP retransmission timer is described in RFC 6298 (see https://datatracker.ietf.org/doc/html/rfc6298). Assuming that the first retransmission timeout (RTT) measurement is R = 40 ms and the clock granularity is G = 50 ms, use the RFC 6298 guidance to determine the retransmission timeout (RTO) if the next two RTT measurements are equal to 50 ms and 55 ms, respectively.
