How to Increase Network Bandwidth in 6 Quick Steps

By Staff Contributor on June 29, 2023

Many IT admins find as the demand for network resources grows, the importance of having a fine-tuned, well-functioning network only increases. If you aren’t careful, all those high-energy applications can put a serious strain on your bandwidth, reducing your overall network performance. Everyone knows it’s good to have high bandwidth to keep these problems from occurring, but the question of how to increase bandwidth isn’t always easily answered. Luckily, there are ways of attaining high bandwidth without buying unnecessary hardware and driving up your costs.

Choosing the Right Tool to Increase Bandwidth

In this piece, I’ll examine how bandwidth is measured, how to check bandwidth, and how to increase bandwidth. I’ll also take a closer look at some of the network monitoring and optimization tools capable of helping you free up your network capacity and improve performance more cheaply, including my personal favorites, SolarWinds® Network Bandwidth Analyzer Pack and SolarWinds NetFlow Traffic Analyzer (NTA).

What Is Bandwidth?

Before we can start talking about how to increase bandwidth, it’s helpful to review what exactly bandwidth is. Bandwidth is often confused with other metrics like speed and latency, but the term “bandwidth” refers to the highest rate of data transmission a network can achieve during a specific time period. This means if a network has high bandwidth, it’s able to transmit and receive a higher amount of data than a network with low bandwidth.

A good analogy for bandwidth is to think of it as a freeway with a strict speed limit. The cars (or data) on the freeway all need to travel at the same speed, so the only way you can get more cars on the freeway (or more data from the internet) is to increase the width of the freeway. If you need five cars to arrive at a destination but you only have one lane on the freeway, it’ll take longer for all the cars to arrive than if you have five lanes. The same is true for bandwidth, except the lanes are replaced by bits per second.

Remember, high bandwidth doesn’t necessarily guarantee overall optimal network performance. It’s only one of a number of factors—including latency, jitter, and packet loss—contributing to network speed. However, it still plays an important role, and without high bandwidth, your speed and performance will suffer.

How to Check Bandwidth?

To explain how to check bandwidth, we first need to answer the question “How is bandwidth measured?” Bandwidth is measured in gigabits per second (Gbps), megabits per second (Mbps), or bits per second (bps). Your internet service provider (ISP) will give you a certain amount of bandwidth based on your contract. If your network is running slowly, you need to check your bandwidth to identify which devices are using too much.

Manually checking bandwidth can be challenging. The only way to do it is to examine the bandwidth usage levels for each individual device on your network, and this can give you insight into which applications are using the most bandwidth. If you have administrative access, you might also be able to check traffic statistics for your routers, firewalls, or switches. Unfortunately, this manual checking won’t give you a sense of historical usage and overall trends, which can have a greater bearing on your bandwidth than a single spot check.

Manually checking bandwidth on each device is a time-consuming and often unreliable process, which is why the best way to check bandwidth is by using an automated bandwidth monitoring tool designed to constantly track traffic network usage. This allows you to get a real-time, centralized view of bandwidth usage across your network alongside other relevant performance details about your network devices. With a bandwidth monitoring solution, you can more easily identify the types of devices and activities using up the most bandwidth and determine whether they’re using the bandwidth appropriately.

6 Steps to Increase Bandwidth

How to Increase Bandwidth

This is the million-dollar question. Fortunately, there’s an answer. There are six main steps to consider when talking about increasing bandwidth:

1.   Get a picture of your current network performance

Before you can start taking steps to optimize your performance, you first need to understand the current state of your performance and bandwidth. The best way to do this is by using a network performance monitor and bandwidth analyzer.

2.   Streamline your data flows

When it comes to improving your network performance, you want to make sure your data flows from one point to another are as streamlined and efficient as possible. Creating subnets for different parts of your network and changing topologies can help with streamlining your data flows and can also help reduce areas where bottlenecks occur.

3.   Optimize the data itself

One of the best ways to increase bandwidth is by optimizing your data through techniques like load balancing and traffic shaping. Through these optimization efforts, you can make the data use less bandwidth overall or create a priority system to let your most critical data act as though there’s more bandwidth available than there actually is. You can perform data optimization at multiple points throughout your network.

4.   Get rid of any unnecessary data on your network

You need to make sure your business has clear policies dictating which applications, websites, and services can be accessed through your business network. You can even create blacklists and whitelists to help you deal with overly bandwidth-intensive services and websites. Another good idea is to create an email attachment policy so your employees know how to send data through your network more efficiently.

5.   Make sure you’re conducting backups and updates at the right time

Backups and updates are essential for any organization, but they also take up a huge amount of bandwidth and can even involve the shutdown of some of your network functions. If you aren’t running these operations at strategic times, you can create latency and cut into network performance. Make sure all your backups and updates occur outside of your normal working hours so the network is free when your employees need it.

6.   Invest in a tool to increase bandwidth

If you really want to increase your bandwidth, the best way to do so is by investing in a network performance tool offering traffic and bandwidth monitoring and analysis. These tools give you the understanding of your current network and bandwidth you need to take steps to improve performance, and they can also help you take targeted steps to increase bandwidth without investing in unnecessary hardware.
