Link aggregation is a method of joining multiple network connections in parallel to create a single, high-capacity logical link. Network administrators typically use this technique to increase backbone capacity between switches or to support high-speed data pipelines for servers. A fundamental for effective switch management, if you have a switch with a whole lot of Gigabit Ethernet ports, you can connect all of them to another device that also has a. Link aggregation is the practice of bundling multiple physical Ethernet links into a single logical connection between two devices. Instead of one cable at 10G, you might have: Of course, as we'll see later, each flow does not get 40G, but in aggregate, you can use all the links.
