In data communications, the bandwidth-delay product is the product of a data link's capacity (in bits per second) and its round-trip delay time (in seconds). [1] The result, an amount of data measured in bits (or bytes), is equivalent to the maximum amount of data on the network circuit at any given time, i.e., data that has been transmitted but not yet acknowledged.
In telecommunications, round-trip delay (RTD) or round-trip time (RTT) is the amount of time it takes for a signal to be sent plus the amount of time it takes for acknowledgement of that signal having been received. This time delay includes propagation times for the paths between the two communication endpoints. [1]
Round trip time estimation is based only on unambiguous acknowledgments, which are acknowledgments for segments that were sent only once. This simplistic implementation of Karn's algorithm can lead to problems as well. Consider what happens when TCP sends a segment after a sharp increase in delay. Using the prior round-trip time estimate, TCP ...
When DFW opened in January 1974, Airtrans, which had been heralded as "people mover of the future,' quickly fell short of expectations. Originally operating between 7 a.m. and 10 p.m., it worked reliably only 56 percent of the time. A more serious problem was the budget.
It has been suggested that this article be merged into Round-trip format conversion. ( Discuss ) Proposed since January 2025. Round-tripping in computer sciences refers to the process of converting data from one format or system to another and then back again to the original format or system, ensuring that the data remains unchanged throughout ...
The algorithm uses the maximum bandwidth and round-trip time at which the network delivered the most recent flight of outbound data packets to build a model of the network. Each cumulative or selective acknowledgment of packet delivery produces a rate sample that records the amount of data delivered over the time interval between the ...
