How did we got this value??

TCP Futures: TCP over long, fat pipes * example: 1500 byte segments, 100ms RTT, want TO Gbps throughput * requires W = 83,333 in-flight segments * throughput in terms of segment loss probability, L [Mathis 1997] 1.22 MSS TCP throughput = RTT VI S to achieve 10 Gbps throughput, need a loss rate of L : 2:10-10 Da very small loss rate! * new versions of TCP for high-speed Transport Layer
