Christian WellsIn the world of networking, optimizing bandwidth utilization, reducing latency, and mitigating packet loss are crucial factors in ensuring a smooth and efficient web surfing experience. One way to achieve these goals is by enabling TCP BBR (Bottleneck Bandwidth and Round-Trip Time) on your Linux desktop. By default, Linux relies on the Reno and CUBIC congestion control algorithms, but enabling BBR can significantly enhance network performance.
In this article, we will guide you through the process of enabling TCP BBR on Ubuntu 23.10. We’ll cover the necessary commands and configuration files, allowing you to optimize your network for seamless browsing. So, let’s get started!
Checking Available Congestion Control Algorithms
Before enabling BBR, it’s essential to ensure that it is supported by your system. To do this, you can check the available congestion control algorithms using the following command:
sysctl net.ipv4.tcp_available_congestion_control
The output will display a list of supported algorithms, such as Reno and CUBIC. If BBR is not listed, you may need to update your Linux kernel to a version that supports BBR.
Checking the Current Congestion Control Algorithm
To verify the congestion control algorithm currently in use on your system, run the following command:
sysctl net.ipv4.tcp_congestion_control
The output will indicate the algorithm being used. If it displays “cubic,” it means that your system is currently utilizing the CUBIC algorithm.
Enabling TCP BBR in Ubuntu
To enable TCP BBR, you need to modify the system’s configuration file. Here’s how you can do it:
- Open the
/etc/sysctl.confconfiguration file using a text editor. For example, you can use the nano editor by running the following command:
nano /etc/sysctl.conf
- Scroll to the end of the file and add the following lines:
net.core.default_qdisc=fq net.ipv4.tcp_congestion_control=bbr
These lines configure the default queuing discipline (qdisc) to “fq” and set the congestion control algorithm to “bbr.”
- Save the file and exit the text editor.
- To apply the changes, refresh the system’s configuration by running the following command:
sysctl -p
The output will confirm that the changes have been applied.
Verifying if BBR is Enabled
To verify if BBR is successfully enabled on your system, use the following command:
sysctl net.ipv4.tcp_congestion_control
If the output displays “bbr,” it means that TCP BBR is now the active congestion control algorithm on your Ubuntu 23.10 system.
Congratulations! You have successfully enabled TCP BBR on your Linux desktop, enhancing your network performance and improving your web browsing experience.
