Exploring SD-WAN Solutions Configuring multiple routers connected to different circuits (for example, an MPLS link and a broadband Internet link) to route network traffic efficiently and optimally can be challenging. In many cases, you may be limited to a simple round-robin load balancing option, particularly if you don't have networking staff available in your various remote locations. Beyond simple load balancing, available bandwidth capacity may go unused during periods of congestion. For example, your broad- band Internet connection may be running slowly during a given period of time, while your costly MPLS link is relatively uncon- gested and may actually be able to provide faster Internet con- nectivity. The inability to aggregate disparate links means wasted bandwidth capacity and lower employee satisfaction.
