OSI layer 2 (data link layer, e. 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. The three layers of a traditional three-layer network design are the core layer, aggregation layer, and access layer. Faster replacement and priority support, covered for 5 years. High-performance 10G SFP modules for optimal connectivity. Link aggregation increases total bandwidth beyond what a single connection could sustain, and provides redundancy where all but one of the physical links. Load sharing is loosely defined as spreading network traffic across 2 or more equal or unequal links/paths. While load sharing often provides the slowest recovery time (dependent on implementation and failure), it is the. IEEE 802. Aggregating multiple links between physical interfaces creates a single logical point-to-point trunk link or a LAG.
