Variability in TCP round-trip times
We measured and analyzed the variability in round trip times (RTTs) within TCP connections using passive measurement techniques. We collected eight hours of bidirectional traces containing over ¢£¢ million TCP connections between end-points at a large university campus and almost ¤ million remote locations. Of these, we used over ¤ million TCP connections that yield ¤¦¥ or more valid RTT samples, to examine RTT variability within a TCP connection. Our results indicate that contrary to observations in several previous studies, RTT values within a connection vary widely. Our results have implications for designing better simulation models, and understanding how round trip times affect the dynamic behavior and throughput of TCP connections.
