What does Load Balancing Router mean?
A load balancing router enables load balancing and sharing in a network with multiple Internet connectivity options or network link resources. It combines the cumulative bandwidth speed of different connections to provide a unified Internet connection and reduce latency while sharing, transferring and shuffling network bandwidth.
Techopedia explains Load Balancing Router
A load balancing router optimizes and improves network bandwidth speed, overall performance and Internet redundancy through several techniques, such as bandwidth aggregation, used to bond the bandwidth capacity of DSL, cable, T1 or any other Internet connection.
Overall traffic can be dynamically distributed across each connection or manually configured. Configuration is implemented in the load balancing router interface and associates a specific service with an Internet connection. For example, Web/network services requiring high bandwidth may be assigned a T1 or the highest available bandwidth connection.
A load balancing router also provides redundancy by transferring Internet connections between networks in the event of a failed connection. Moreover, some load balancing routers provide the ability to learn, identify, use and switch between best available network paths.
