The formula for calculating throughput: throughput = number of concurrencies/average response time, Throughput is the amount of data (measured in bits, bytes, packets, etc.) successfully transmitted per unit of time to a network, device, port, virtual circuit, or other facility.

Throughput is the amount of data (measured in bits, bytes, packets, etc.) successfully transmitted per unit of time, to a network, device, port, virtual circuit, or other facility.

Definition:Firewall throughput is the maximum data rate that a device can receive and forward without frame loss.

The size of the throughput is mainly determined by the internal and external network port hardware of the network equipment, and the efficiency of the program algorithms, especially the program algorithms, for devices like firewall systems that require a lot of calculations, the inefficiency of the algorithms will make the communication greatly reduced.

Therefore, most firewalls are called 100M firewalls, because their algorithms rely on software to realize, the communication volume is far from 100M, the actual only 10M-20M. Pure hardware firewalls, due to the use of hardware computing, so the throughput can be close to the line speed, up to 90-95M, the real 100M firewalls.

Throughput and message forwarding rate is the relationship between the main indicators of the application of network equipment, generally used FDT (Full Duplex Throughput) to measure, refers to the full-duplex throughput of 64-byte packets, this indicator includes both throughput indicators also covers the message forwarding rate indicators.

The throughput is tested by sending a certain number of frames at a certain rate and counting the frames transmitted by the device to be tested; if the number of frames sent is equal to the number of frames received, then the sending rate is increased and the test is retested; if the number of frames received is less than that of frames sent, then the sending rate is reduced and the test is retested until the final result is obtained. Throughput test results are expressed in bits/second or bytes/second.
