Software-defined networks (SDNs) offer several advantages over traditional networks; one key advantage is their distributed management architecture. Unlike traditional networks where the control plane (which makes decisions about where traffic should be sent) and the data plane (which actually sends packets according to those decisions) are coupled on each networking device leading to potential single points of failure, SDNs separate these planes. This separation allows for centralized control with a global view of the network state while maintaining local data forwarding at each switch. This architecture enhances resilience as it can dynamically adjust and reroute traffic around failed nodes or congested paths without manual intervention.
