The TCP Minimum RTO Revisited

The TCP Minimum RTO Revisited
We re-examine the two reasons for the conservative 1-second Minimum TCP-RTO to protect against spurious timeouts: i) the OS clock granularity and ii) the Delayed ACKs. We find that reason (i) is canceled in modern OSs; we carefully design a mechanism to deal with reason (ii). Simulation results show that in next generation’s high-speed, wirelessaccess networks, TCP-RTO should not be limited by a fixed, conservative lower bound. Key words: TCP, Minimum RTO, High Speed Links, Last Mile Wireless
