Network Throughput Calculator
This tool estimates TCP throughput and file transfer time based on network link characteristics and TCP/IP parameters.
Link bandwidth (Mbit/s): 
RTT (millisecond): 
Packet loss (%): 
MTU (Byte): 
L1/L2 frame overhead (Byte): 
TCP/IP (v4) header overhead (Byte): 
TCP window (RWND) size (Byte): 
File size (MByte): 
Results:



Link bandwidth (Mbit/s): 
10

Max achievable TCP throughput limited by TCP overhead (Mbit/s): 
9.4928

Bandwidth-Delay Product (BDP) (bit): 
800000

Minimum required TCP RWND (Byte): 
100000

Max TCP throughput limited by packet loss (Mathis et.al. formula) (Mbit/s):
146

Max TCP throughput limited by TCP RWND (Mbit/s): 
1677.721600

Expected maximum TCP throughput (Mbit/s): 
9.4928

Minimum transfer time for a 100 MByte file (d:h:m:s): 
0:00:01:24
