Throughput is controlled by available bandwidth, as well as the available signal-to-noise ratio and hardware limitations. Throughput for the purpose of this article will be understood to be measured from the arrival of the first bit of data at the receiver, to decouple the concept of throughput from the concept of latency.
It specifies the latency for a bit of data to travel across the network from one communication endpoint to another. [1] [2]: 5 It is typically measured in multiples or fractions of a second. Delay may differ slightly, depending on the location of the specific pair of communicating endpoints.
The naïve roofline [3] is obtained by applying simple bound and bottleneck analysis. [8] In this formulation of the roofline model, there are only two parameters, the peak performance and the peak bandwidth of the specific architecture , and one variable, the arithmetic intensity .
The asymptotic throughput (less formal asymptotic bandwidth) for a packet-mode communication network is the value of the maximum throughput function, when the incoming network load approaches infinity, either due to a message size, [3] or the number of data sources.
Bandwidth test software is used to determine the maximum bandwidth of a network or internet connection. It is typically undertaken by attempting to download or upload the maximum amount of data in a certain period of time, or a certain amount of data in the minimum amount of time.
Latency, from a general point of view, is a time delay between the cause and the effect of some physical change in the system being observed. Lag , as it is known in gaming circles , refers to the latency between the input to a simulation and the visual or auditory response, often occurring because of network delay in online games.
Register the paths along data flow; Calculate worst-case latency; Create an AVB domain; Reserve the bandwidth; Resources are allocated and configured in both the end nodes of the data stream and the transit nodes along the data flow path, with an end-to-end signaling mechanism to detect the success/failure.
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.
