Link aggregation, also known as port trunking, is a method of increasing bandwidth by combining physical network links into a single logical link. Link aggregation increases the capacity and availability of the communications channel between devices (both switches and end stations) by using Fast Ethernet and Gigabit Ethernet technology.
Multiple parallel physical links between two devices can be grouped together to form a single logical link. Link aggregation also provides load balancing where processing and communications activities are distributed across several links in a trunk. This prevents single link overloading.
The LinkProof Link Aggregation feature allows defining up to seven trunks. Up to eight physical links can be aggregated into one trunk. All trunk configurations are static.
To provide optimal distribution for different scenarios the load sharing algorithm allows decisions based on source or destination (or both) L2 address (MAC), L3 address (IP), and L4 address (TCP/UDP port numbers). These parameters are used as input for a hashing function.
