Bandwidth is measured (or sampled) from the switch or router and recorded in a log file.In most cases, this is done every 5 minutes. At the end of the month, the samples are sorted from highest to lowest, and the top 5% (which equal to approximately 36 hours of a 30-day billing cycle) of data is thrown away.
Example of calculation of Average Per-Bit Delivery Cost for a small data-flow. Average Per-Bit Delivery Cost divides the cost of however many bits were actually modulated across a network or component of a network over a period of time by the total operational and amortized capital expenses associated with the network or component over the same time-period, to produce an average cost for the ...
The route will go in the direction of the gateway with the lowest metric. A router metric is typically based on information such as path length , bandwidth , load , hop count , path cost, delay , maximum transmission unit (MTU), reliability and communications cost.
STP will select the path with the lowest cost, that is the highest bandwidth, as the preferred link. ... (4 bits) + locally assigned system ID extension (12 bits ...
The knee frequency is related to the required bandwidth of a channel, and can be related to the 3 db bandwidth of a system by the equation: [8] / Where Tr is the 10% to 90% rise time, and K is a constant of proportionality related to the pulse shape, equal to 0.35 for an exponential rise, and 0.338 for a Gaussian rise.
A typical method of performing a measurement is to transfer a 'large' file from one system to another system and measure the time required to complete the transfer or copy of the file. The throughput is then calculated by dividing the file size by the time to get the throughput in megabits , kilobits , or bits per second.

The ISQ symbols for the bit and byte are bit and B, respectively.In the context of data-rate units, one byte consists of 8 bits, and is synonymous with the unit octet.The abbreviation bps is often used to mean bit/s, so that when a 1 Mbps connection is advertised, it usually means that the maximum achievable bandwidth is 1 Mbit/s (one million bits per second), which is 0.125 MB/s (megabyte per ...
