In [[communication networks]], '''network throughput''' (or just '''throughput''', when in context) is the rate of successful message delivery over a communication channel, such as [[Ethernet]] or [[packet radio]]. The data these messages belong to may be delivered over a physical or logical link, or it can pass through a certain [[network node]]. 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-division multiplexing|time slot]].

The '''system throughput''' or '''aggregate throughput''' is the sum of the data rates that are delivered to all terminals in a network.<ref>[[Guowang Miao]], Jens Zander, K-W Sung, and Ben Slimane, Fundamentals of Mobile Data Networks, Cambridge University Press, {{ISBN|1107143217}}, 2016.</ref> Throughput is essentially synonymous to [[digital bandwidth consumption]]; it can be analyzed mathematically by applying the [[queueing theory]], where the load in packets per time unit is denoted as the arrival rate ({{mvar|λ}}), and the throughput, where the drop in packets per unit time unit, is denoted as the departure rate ({{mvar|μ}}).

The throughput of a communication system may be affected by various factors, includingsuch as the limitations of underlying analog physical medium, available processing power of the system components, and [[end-user]] behavior and so on. When various protocol overheads are taken into accountconsideration, useful rate of the transferred data transfer can be significantly lower than the maximum achievable throughput; the useful part is usually referred to as [[goodput]].
