What Is the Definition of Throughput

System throughput, or aggregate throughput, is the sum of the data rates provided to all endpoints in a network. [1] Throughput is essentially equivalent to digital bandwidth consumption. It can be analyzed mathematically by applying queue theory, which refers to packet load per unit of time such as arrival rate (λ) and throughput, where the decrease in packets per unit of time is called the output rate (μ). For example, the maximum frame size in Ethernet is 1526 bytes: up to 1500 bytes for the payload, eight bytes for the preamble, 14 bytes for the header, and 4 bytes for the trailer. An additional minimum interval of 12 bytes between frames is inserted after each frame. This equates to a maximum channel usage of 1526/(1526+12) × 100% = 99.22% or a maximum channel usage of 99.22 Mbps, including overloading the Ethernet data link layer protocol in a 100 Mbps Ethernet connection. The maximum throughput or channel efficiency is then 1500 / (1526 + 12) = 97.5%, without the overload of the Ethernet protocol. This number is closely related to the capacity of the system channel[2] and is the maximum amount of data that can be transmitted under ideal circumstances. In some cases, this number is given as equal to the capacity of the channel, although this can be misleading because only non-packaged (asynchronous) system technologies can achieve this without data compression. The maximum theoretical throughput is specified more precisely to fit the format and specification overhead with the best assumptions. This number, like the closely related term „maximum achievable flow“ below, is mainly used as a roughly calculated value, i.B. to determine possible performance limits at the beginning of a system design phase. However, ABC must also communicate with its suppliers of bicycle frames and metal seats and get them to supply these components when they are needed for production.

If parts don`t arrive when ABC Cycles needs them, the company`s throughput is lower. „We need to have an idea of what regular production will look like, what the manufacturer`s throughput is, so we can look more than a week in advance,“ he said. We exchange flow for intensity and make it a high-end product. In wireless networks or cellular systems, the spectral efficiency of the system in bits/s/Hz/unit, bits/s/Hz/site or bits/s/Hz/cell is the maximum system throughput (aggregate rate) divided by analog bandwidth and some measure of the system coverage area. The above values are theoretical or calculated. The measured peak flow is the flow measured by an actual implemented system or a simulated system. The value is the flow measured over a short period of time; Mathematically, this is the limit taken in terms of flow when time approaches zero. This term is synonymous with immediate throughput.

This number is useful for systems that rely on burst data transfer. However, for systems with a high duty cycle, this is less likely to be a useful measure of system performance.

Asymptotic throughput is typically estimated by sending or simulating a very large message (sequence of data packets) over the network, using a greedy source rather than a flow control mechanism (i.e. UDP instead of TCP), and measuring the throughput of the network path in the target node. Traffic load between other sources can reduce this maximum network path throughput.

Alternatively, a large number of sources and sinks can be modeled with or without flow control and the aggregate maximum network throughput (the sum of traffic reaching its destinations) can be measured. In a network simulation model with infinite packet queues, asymptotic throughput occurs when latency (packet latency) passes to infinity, while packet queues are limited or the network is a multi-drop network with many sources and collisions can occur, the packet drop rate reaches 100%. In many cases, two products can be added to production using the same process, which means that common costs are shared between each product. However, when production reaches the point of separation, the products are manufactured in separate processes. This makes it difficult to maintain a high level of throughput. These sample sets are automatically selected from various online information sources to reflect the current use of the word „throughput“.

To determine the actual data rate of a network or connection, the measurement definition „Goodput“ can be used. For example, in file transfer, the „Goodput“ is the size of the file (in bits) divided by the file transfer time.

The „goodput“ is the amount of useful information that is transmitted to the application layer protocol per second. Ignored packets or packet retransmissions as well as protocol overload are excluded. For this reason, the „Goodput“ is lower than the flow rate. The technical factors that affect the difference are presented in the article „Goodput“. Often, a block in a data flow diagram has a unique input and output and works with discrete information packets. Examples of such blocks are fast Fourier transform modules or binary multipliers. Since the throughput units are the reciprocal of the propagation delay unit, which is „seconds per message“ or „seconds per output“, the throughput can be used to connect a computing device that performs a dedicated function such as an ASIC or processor integrated into a communication channel, simplifying system analysis. First of all, medicine became a business, and while we had time to get to know patients and really build relationships, now it`s much more about flow and how many people you can squeeze into an afternoon. This value is the averaged or integrated throughput over a long period of time (sometimes considered infinite). For high-duty cycle networks, this is probably the most accurate indicator of system performance.

The maximum throughput is defined as the asymptotic throughput when the load (the amount of incoming data) is very large. .
