So our bandwidth delay product is 2500000 bits. It plays an especially important role in high-speed / high-latency networks, such as most. Bandwidth Delay Product bandwidth (bits per sec) round trip time (in seconds) So for example, let’s calculate the bandwidth delay product of a satellite link that has a round trip time of 500 ms: 5000000 bits 0.5 seconds bandwidth delay product 2500000. BDP is a very important concept in a Window based protocol such as TCP. We can calculate it with the following formula: Bandwidth Delay Product bandwidth (bits per sec) round trip time (in seconds) So for example, let’s calculate the bandwidth delay product of a satellite link that has a round trip time of 500 ms: 5000000 bits 0.5 seconds bandwidth delay product 2500000. It is the product of the availalbe bandwidth and the latency, or RTT. Slow light photonic crystal waveguideswith large delay-bandwidth product Mohammad Pourmand - Arash Karimkhani - Mohammad Kazem Moravvej Farshi Optical. In a congested path, the TCP throughput is maximized when the connection is limited by the congestion window, rather than by the socket buffers. The BandwidthDelay Product, or BDP for short determines the amount of data that can be in transit in the network. 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.
We show 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 this paper, we re-examine the BDP concept, considering the effects of network buffering and cross traffic on the `bandwidth' and `delay' characteristics of a path. The BDP is of fundamental importance because it determines the required socket buffer size for maximum throughput. TCP is often blamed that it cannot use efficiently network paths with high Bandwidth-Delay Product (BDP).
