Bandwidth-delay product is the product of a data link's capacity (in bits per second) and its round-trip delay time (in seconds). |
|||
Includes data in queues if they contributed to the delay |
|||
The result data is equivalent to the maximum amount of data on the network circuit at any given time, Or data that has been transmitted but not yet acknowledged. |
|||
BDP (bytes) = total_available_bandwidth (bps) x round_trip_time (sec) / 8 |
|||
A network with a large bandwidth-delay product is commonly known as a Long Fat Network(LFN). |
|||
A network is considered an LFN if its bandwidth-delay product is significantly larger than 105 bits (12,500 bytes). |
