More is being required today of network infrastructure than ever before, due in part to the changing latency and bandwidth needs of modern applications. Wide area networks (“WANs”) are feeling the pressure, especially those that use many technologies from different services providers, are geographically diverse and are stretched to the limit by increased video and cloud app usage.
In view of these challenges, hybrid WAN architectures with advanced application-level traffic routing are of particular interest. They combine the reliability of private lines for critical business applications with the cost-effectiveness of broadband/Internet connectivity for non-critical traffic.
