TCP throughput calculator

Calculate theoretical network limit

simplified formula: rate MSS: Byte MSS (maximum segment size) typ. MTU-40B (TCP/IP header) RTT: ms round trip time Loss: % Loss rate in %. typ. -6% (-8)

Calculate Bandwidth-delay Product and TCP buffer size

BDP ( Bits of data in transit between hosts) = bottleneck link capacity (BW) * RTT

throughput = BW * RTT

BW: Mbps required or minimum available bandwidth RTT: ms round trip time WIN: KByte required or available TCP buffer size
