What is meant by "Ethernet segmentation"?

"Ethernet segmentation" refers to the practice of dividing a local area network (LAN) into smaller, manageable segments. This approach has several benefits for network performance and efficiency. Segmenting a network helps to reduce collision domains, which can lead to increased overall throughput as fewer devices compete for the same bandwidth. Each segment can operate independently, which isolates traffic and minimizes broadcast traffic, helping to enhance network reliability and security as well.

This practice can be achieved using various means, such as switches or routers, which facilitate the separation of network segments. By implementing segmentation, network administrators can also implement targeted security measures and traffic management policies for different segments based on their unique requirements, further optimizing the network’s performance and security posture.

In summary, Ethernet segmentation is focused on creating smaller, isolated segments within a larger network to improve performance and manageability.
