Purpose of Link Aggregation

Table of Content [Hide]

    Link Aggregation combines multiple physical network connections (such as Ethernet cables) into a single logical connection. This logical link is typically referred to as a Link Aggregation Group (LAG), also known as EtherChannel or bonded link. The key objectives of ethernet switch link aggregation are as follows:

    1. Increased Bandwidth

    The most immediate benefit of link aggregation is higher switching bandwidth. Since a single physical link has limited capacity, bundling multiple links together multiplies the available bandwidth. For example, aggregating four 1Gbps links can theoretically provide a total bandwidth of 4Gbps.

    2. Improved Reliability

    If one physical link fails, traffic is automatically redirected to the remaining functional links, ensuring continuous network communication. This redundancy enhances network reliability and stability.

    3. Load Balancing

    Link aggregation distributes network traffic evenly across multiple physical links, preventing congestion on any single link. This optimizes bandwidth utilization and improves overall transmission efficiency.
