IEEE link aggregation Standardization process īy the mid 1990s, most network switch manufacturers had included aggregation capability as a proprietary extension to increase bandwidth between their switches. The former requires that both ends of a link use the same aggregation method, but has performance advantages over the latter.Ĭhannel bonding is differentiated from load balancing in that load balancing divides traffic between network interfaces on per network socket (layer 4) basis, while channel bonding implies a division of traffic between physical interfaces at a lower level, either per packet (layer 3) or a data link (layer 2) basis.

MAC address), or it allows each interface to have its own address. Most methods provide failover as well.Ĭombining can either occur such that multiple interfaces share one logical address (i.e. However, in order to avoid out-of-order delivery, not all implementations take advantage of this. Regardless of the layer on which aggregation occurs, it is possible to balance the network load across all links. Aggregation at layer 3 ( network layer) in the OSI model can use round-robin scheduling, hash values computed from fields in the packet header, or a combination of these two methods. Ethernet frame in LANs or multi-link PPP in WANs, Ethernet MAC address) aggregation typically occurs across switch ports, which can be either physical ports or virtual ones managed by an operating system. IEEE 802.11) network devices that combine multiple frequency bands. Examples of aggregation at layer 1 ( physical layer) include power line (e.g. Network architects can implement aggregation at any of the lowest three layers of the OSI model. Combining multiple physical connections into one logical connection using link aggregation provides more resilient communications. Multiple logical connections can be made, but many of the higher level protocols were not designed to fail over completely seamlessly. There are three single points of failure inherent to a typical port-cable-port connection, in either a computer-to-switch or a switch-to-switch configuration: the cable itself or either of the ports the cable is plugged into can fail.

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.
