Für Netzwerkverwalter sind Routing-Protokolle wie BGP (Border Gateway Protocol) oder OSPF (Open Shortest Path First) nervig. Router entsprechend zu konfigurieren, kostet Zeit und Nerven. Zudem kommen diese Protokolle ihrer Aufgabe, sprich den besten Pfad durch das Internet zu finden, oft nur unzureichend nach. Denn häufig dauert es schlichtweg zu lange, bis ein Protokoll eine alternative Route findet, wenn der Hauptweg versperrt oder überlastet ist.
Doch was tun? Einen Ausweg bieten Software-Defined WANs (Wide Area Networks), kurz SD-WANs. Sie weisen nicht die Limitierungen von BGP und Co. auf.
