TCP Throughput Calculator

Network performance depends on more than only available bandwidth

TCP throughput calculator

Theoretical network limit
rough estimation: rate < (MSS/RTT)*(C/sqrt(Loss)) [ C=1 ] (based on the Mathis et.al. formula)
network limit (MSS 1460 byte, RTT: 2.0 ms, Loss: 10-08 (10-06%)) : 58400.00 Mbit/sec.
Bandwidth-delay Product and buffer size
BDP (1000 Mbit/sec, 2.0 ms) = 0.25 MByte
required tcp buffer to reach 1000 Mbps with RTT of 2.0 ms >= 244.1 KByte
maximum throughput with a TCP window of 256 KByte and RTT of 2.0 ms <= 1048.58 Mbit/sec.
