Most of these early solutions required manual configuration and identical equipment on both sides of the connection. An alternative solution, introduced by many of the network manufacturers in the early 1990s, is to use link aggregation to combine two physical Ethernet links into one logical link. If one started to bump into bandwidth ceilings, then the only option was to move to the next generation, which could be cost prohibitive. Ethernet bandwidths historically have increased tenfold each generation: 10 megabit/s, 100 Mbit/s, 1000 Mbit/s, 10,000 Mbit/s. Link aggregation increases the bandwidth and resilience of Ethernet connections.īandwidth requirements do not scale linearly. Implementation may follow vendor-independent standards such as Link Aggregation Control Protocol (LACP) for Ethernet, defined in IEEE 802.1AX or the previous IEEE 802.3ad, but also proprietary protocols.

Other umbrella terms used to describe the concept include trunking, bundling, bonding, channeling or teaming.

A link aggregation group ( LAG) is the combined collection of physical ports. Link aggregation increases total throughput beyond what a single connection could sustain, and provides redundancy where all but one of the physical links may fail without losing connectivity. In computer networking, link aggregation is the combining ( aggregating) of multiple network connections in parallel by any of several methods.
