![]() This number, like the closely related term 'maximum achievable throughput' below, is primarily used as a rough calculated value, such as for determining bounds on possible performance early in a system design phase. Maximum theoretical throughput is more accurately reported taking into account format and specification overhead with best case assumptions. In some cases this number is reported as equal to the channel capacity, though this can be deceptive, as only non-packetized systems (asynchronous) technologies can achieve this without data compression. ![]() This number is closely related to the channel capacity of the system, and is the maximum possible quantity of data that can be transmitted under ideal circumstances. ![]() The lowest value link in the series is referred to as the bottleneck. If the communication is mediated by several links in series with different bit rates, the maximum throughput of the overall link is lower than or equal to the lowest bit rate. Data compression can significantly alter throughput calculations, including generating values exceeding 100% in some cases. Each bit must carry the same amount of information if throughput values are to be compared. These values represent different quantities, and care must be taken that the same definitions are used when comparing different 'maximum throughput' values. They are 'maximum theoretical throughput', 'maximum achievable throughput', and 'peak measured throughput' and 'maximum sustained throughput'. Maximum throughput is essentially synonymous to digital bandwidth capacity.įour different values are relevant in the context of "maximum throughput", used in comparing the 'upper limit' conceptual performance of multiple systems. The term maximum throughput is frequently used when discussing end-user maximum throughput tests. In most cases, the benchmark of what a system is capable of, or its "maximum performance" is what the user or designer is interested in. Systems designers are often interested in selecting the most effective architecture or design constraints for a system, which drive its final performance. From a user perspective, this is often phrased as either "which device will get my data there most effectively for my needs?", or "which device will deliver the most data per unit cost?". Users of telecommunications devices, systems designers, and researchers into communication theory are often interested in knowing the expected performance of a system. When taking various protocol overheads into account, the useful rate of the data transfer can be significantly lower than the maximum achievable throughput the useful part is usually referred to as goodput. The throughput of a communication system may be affected by various factors, including the limitations of the underlying analog physical medium, available processing power of the system components, end-user behavior, etc. Throughput is essentially synonymous to digital bandwidth consumption it can be determined numerically by applying the queueing theory, where the load in packets per time unit is denoted as the arrival rate ( λ), and the drop in packets per unit time is denoted as the departure rate ( μ). The system throughput or aggregate throughput is the sum of the data rates that are delivered to all terminals in a network. Throughput is usually measured in bits per second (bit/s or bps), and sometimes in data packets per second (p/s or pps) or data packets per time slot. Network throughput (or just throughput, when in context) refers to the rate of successful message delivery over a communication channel, such as Ethernet or packet radio, in a communication network.The data that these messages contain may be delivered over physical or logical links, or through network nodes.
