![]() While there is no way to measure total available bandwidth, there are many ways to define measured bandwidth, depending on the need. Most internet speed tests use this method to calculate the connection speed of a user’s computer to the internet. The result is converted into bps by dividing the size of the files by the amount of time the transfer required. The resulting measurements are then expressed as a per-second number.Īnother method of measuring bandwidth is to transfer a file, or several files, of known size and count how long the transfer takes. Typically, to measure bandwidth, the total amount of traffic sent and received across a specific period of time is counted. PRTG provides a graphical interface and charts for measuring bandwidth trends over longer periods of time, and can measure traffic between different interfaces. Each side displays the number of bytes transmitted and the time for each packet to complete the one-way trip. One host is the receiver, the other the sender. TTCP measures throughput on an IP network between two hosts. Common bandwidth measuring utilities include the Test TCP utility (TTCP) and PRTG Network Monitor, for example. Measuring bandwidth is typically done using software or firmware, and a network interface. ![]()
