if the node is used as part of a botnet).

Malicious programs – If a node on the network is compromised, you may see a significant spike in traffic (e.g.

The aforementioned points about network hubs and misconfigurations are two possible sources of broadcast storms. A broadcast storm occurs when a network is bogged down by broadcast (or multicast) messages.

Broadcast storms – Broadcasts are messages sent to an entire network segment, which means they generate significantly more traffic than a similar message sent to a single host.

Misconfigurations– An improperly-configured switch, server, or script could lead to congestion on your network.

If there are still network hubs on your network, consider replacing them with switches.

Network hubs – Network hubs do not break up collision domains on a per-port basis.

Think tax services in April or a big sale on an ecommerce site.

Spikes in network traffic – Events that drive more people to a website or server can create bottlenecks.

Examples include an application downloading multiple large files or streaming HD video.

Bandwidth hungry devices – Certain applications or nodes may use a disproportionate amount of bandwidth on your network and create bottlenecks.

There are a number of reasons you may experience network bottlenecks. On the flip side of that coin, if you are a business that provides internet service or otherwise charges for bandwidth consumption, monitoring bandwidth enables accurate billing and helps you ensure you are meeting or exceeding your SLA agreements with customers.Īlternatively, if you’re a home user you may be interested in better understanding how you are using your bandwidth or getting an estimate of how long downloading a file of a given size might take (see #4 on our list if this is you). It can also help you make sure your service providers are living up to their SLAs (Service Level Agreements). Understanding your network’s baseline for bandwidth helps you better plan future projects and catching bottlenecks early can prevent them from becoming a major issue. Monitoring bandwidth enables you to understand the general bandwidth consumption on your network and identify potential bottlenecks. These “traffic jams” are often referred to as “bottlenecks”. As the lanes become more and more congested, traffic slows down. Bandwidth is the number of lanes on that highway. The more lanes the highway has, the more data can move. Common measures of bandwidth are Mbps (megabits per second) and Gbps (gigabits per second).Ī common way to conceptualize this is to imagine network data traveling over a highway. In a nutshell, network bandwidth is a measurement of how much data per second a given connection can support. >Jump to the list of bandwidth monitoring tools below<<< What is bandwidth?

If you’re already comfortable with the topic of bandwidth monitoring, feel free to In this article, we’ll review some of the basics of bandwidth and bandwidth monitoring then we’ll dive into some popular bandwidth monitoring tools available today for Windows, Linux, and more. Bandwidth monitoring can help you identify bottlenecks so you can investigate the underlying issue and establish baselines so you know how your network is performing today. Network bottlenecks can slow down progress or even bring business to a halt. In today’s world, productivity is based in large part on network speed and connectivity.
