Throughput
Hard Drive Recovery - Throughput
Throughput refers to the average rate of successful message delivery over a communication channel. Throughput is usually measured in bits per second (bps) or data packets per second. System throughput or aggregate throughput is the sum of the data rates that are delivered to all terminals in a network.
Throughput is similar to digital bandwidth consumption, and maximum throughput is synonymous to digital bandwidth capacity. It refers to the maximum possible quantity of data that can be transmitted under ideal circumstances. The maximum achievable throughput takes into account handshake and control packets, which reduce the amount of channel space available for data packets. It also includes considerations such as reduced data packet length. Hardware limitations of the system on both ends of the channel are also taken into account.
Peak-measured throughput is a realistic measurement of throughput using a simulated system. The value is measured over a short period of time. It is the limit taken with respect to throughput as time approaches zero. Peak measured throughput is useful for systems that rely on burst data transmission.
Maximum sustained throughput is the average throughput or throughput integrated over a long time. In packet switched network, the load and throughput are always equal. In such cases, maximum throughput is defined as the minimum load in bps that causes the latency to become unstable and increase towards infinity.
Important factors affecting throughput are analog limitations, skin effect, termination and ringing, wireless channel effects, IC hardware, protocol, flow control and multiuser considerations.
