An enterprise network is experiencing difficulties with the manual configuration and management of a large number of network devices, leading to increased operational costs and complexity. The network engineer is considering adopting a controller-based networking model to address these issues. What is a fundamental difference between traditional and controller-based networks that could help solve this problem?
In traditional networks, the control plane and data plane are always separated on different devices to simplify management.
Traditional networks use centralized controllers to automate network device management.
Controller-based networks centralize network management by using a central controller that communicates with all network devices. This centralization allows for unified and automated configuration, policy enforcement, and management across the network, significantly reducing the need for manual configuration of individual devices. In contrast, traditional networks typically require network administrators to configure and manage each device separately, which can be time-consuming and error-prone, especially in large networks. By adopting a controller-based model, the enterprise can streamline network operations and reduce complexity.
