Nowadays we often hear that customers want to use a router feature called Link Aggregation. Here we can simply discuss about the Link Aggregation, also called Link Bonding by other users. What is link aggregation? Link aggregation is a way of bundling a bunch of individual (Ethernet) links together so they act as a single logical link. Why we will use link aggregation? If you have a switch with a lot of Gigabit Ethernet ports, you can connect all of them to another device that also has a bunch of ports and balance the traffic among these links to improve performance. Another important reason for using link aggregation is to provide fast and link recovery in case one of the individual links fails. Individual packets are kept intact and sent from one device to the other over one of the links. In fact, the protocol usually tries to keep whole sessions on a single link. A packet from the next conversation could go over a different link. The idea is to achieve improved performance by tra...
