TCP is often blamed that it cannot use efficiently network paths with high Bandwidth-Delay Product (BDP). The BDP is of fundamental importance because it determines the required socket buffer size for maximum throughput. This paper re-examine the BDP concept, considering the effects of network buffering and cross traffic on the 'bandwidth' and 'delay' characteristics of a path. It shows that, with careful socket buffer sizing, a bulk TCP transfer can saturate a network path independent of the BDP or the available network buffers. In a non-congested path, there is a certain socket buffer size (which depends on the cross traffic type) that maximizes the throughput of a bulk TCP transfer.
