The higher the bandwidth a network has, the more data it can send back and forth. Bandwidth can be measured in bits per second bps megabits per second Mbps and gigabits per second Gbps. If throughput in the network is being affected by network latency , packet loss, and jitter then your service will see delays even if you have a substantial amount of bandwidth available.
The most common analogy used to describe the relationship between the two is to consider bandwidth as a pipe and throughput as water. The larger the pipe or bandwidth is, the more water or data can flow through it at one time.
Within a network, this means that the amount of bandwidth determines how many packets can be sent and received between devices at one time and the amount of throughput tells you how many packets are actually getting transmitted. To put it another way, bandwidth provides you with a theoretical measure of the maximum number of packets that can be transferred and throughput tells you the number of packets that are actually being successfully transferred. As a result, throughput is more important than bandwidth as a measure of network performance.
For instance, bandwidth has a significant influence on how fast a web page will load on a browser. So if you were looking to use web hosting for an application the amount of bandwidth you have available would impact the performance of certain services. A common misconception is that bandwidth can be used as a measure of speed.
We have discussed this briefly above but it is worth revisiting because of how commonly the two are mixed up. If you increase the amount of bandwidth the only thing that changes is that more data can be sent at one time.
The truth is bandwidth is just one of a multitude of factors that tie into the speed of a network. Within a network, speed is a measure of response time. Factors like packet loss and latency impact speed. Bandwidth and latency are also discussed together regularly but each has its own unique meaning. Latency is simply the amount of time that it takes for data to travel from a sender to its destination. The relationship between the two is close, as bandwidth determines how much data can theoretically be sent and received at one time.
However, latency determines how fast these packets actually reach their destination. Minimizing latency is important for keeping the network moving as fast as possible.
If you were looking to measure network performance it makes more sense to use network throughput rather than looking at capacity with bandwidth. Network administrators have a number of ways that they can use to measure for poor performance within an enterprise-grade network. Using throughput to measure network performance is useful when troubleshooting because it helps administrators to pinpoint the root cause of a slow network.
However, it is just one of the three factors that determine network performance. The other two are latency and packet loss :. We reviewed the market for bandwidth monitoring software and analyzed the options based on the following criteria:. SolarWinds Network Bandwidth Analyzer Pack is a product that can accurately measure the throughput of your network.
You can view throughput flow data alongside monitoring bandwidth with SNMP. There is also a network throughput test that can be mixed with pre and post-QoS policy maps to show if your QoS policy is improving the performance of the network over time. See also: What is QOS.
Conducting bandwidth monitoring with a network monitoring tool allows you to see the actual amount of bandwidth available to your connected devices within the network. With SolarWinds NetFlow Traffic Analyzer you can monitor bandwidth availability and identify bandwidth hogs within your network.
Bandwidth hogs are devices or applications that are consuming a large amount of bandwidth. High bandwidth consumption can indicate a poorly-performing device or a device that has been compromised. Once you know which tools are consuming a disproportionate amount of bandwidth within your network you can look for ways to reduce the problem and provide other devices with more service.
This will increase the amount of your bandwidth capacity available to other devices. The pack includes an interface that helps you to configure your Cisco routers to send NetFlow data to your collector. Two more utilities enable you to circulate traffic data around the network for testing purposes and also generate traffic to examine the performance of your equipment and network services in the face of extra demand.
PRTG Network Monitor allows you to autodiscover devices within your network and monitor their traffic usage. PRTG Network Monitor also helps you to deal with bandwidth hogs so that you can see how much bandwidth is being consumed by individual devices and applications. Organizations commonly implement QoS or Quality of Service settings to help the network to support mission-critical applications. Throughput is an achieved value that refers to the actual amount of data transmitted from point A to point B in a defined period of time.
Unlike bandwidth, throughput is a performance metrics that refers to the actual speed of data on a network communication system. It refers to the performance of computing tasks over a given period of time. In simple terms, throughput is the measure of actual rate at which data is transferred over to the destination successfully.
It confirms the actual delivery rather than theoretical delivery of the packet data over a communication channel. The term is synonymous with digital bandwidth consumption. Throughput is usually measured in bits per second bps. Throughput refers to the actual amount of data transmitted from point A to point B in a defined period of time.
As an analogy of a highway, bandwidth refers to the maximum number of vehicles that can get through the highway over a give time period. Throughput is the number of cars that can actually get through.
Throughput is measured in mostly bits per second, or in some cases, in any quantifiable unit related to the process. In networking, throughput is the number of information systems processed per unit of time. A fast gigabit Ethernet achieves a throughput rate of 1 Gbps might require bandwidth transmission rate of 1.
Applications that require maximum throughput include telephone signaling, video conferencing, and online video streaming. Throughput, on the other hand, is quite similar to but slightly different than bandwidth and is concerned with communication between two entities.
Bandwidth refers to a theoretical value whereas throughput refers to an actual achieved value. Both the terms are often confused, but may be used interchangeably depending on the situation. Besides, both are performance metrics used to measure the network performance. Difference Between Bandwidth and Throughput. Difference Between Similar Terms and Objects. MLA 8 Khillar, Sagar.
