A controller architecture offers several advantages over an infrastructure network with autonomous access points (APs):
-
Centralized Management: A controller enables centralized configuration, monitoring, and management of multiple APs, simplifying network administration and reducing the potential for configuration errors.
-
Enhanced Performance: Controllers can optimize resource allocation, load balancing, and channel assignment across APs, resulting in improved overall network performance and user experience.
-
Scalability: It is easier to add new APs to a controller-based architecture, allowing for seamless scaling of the network as demand grows, without significant manual configuration.
-
Advanced Features: Controller architecture often supports advanced features like seamless roaming, application visibility, and integrated security protocols, which are more complex to implement with autonomous APs.
-
Simplified Troubleshooting: Centralized logging and diagnostics tools within the controller can make identifying and resolving issues faster and more efficient than dealing with independent APs.
-
Consistent Policy Enforcement: Controllers can enforce uniform policies across the network, ensuring consistent quality of service and security standards.
Overall, a controller-based architecture provides greater centralized control, optimized performance, and easier management, making it a preferred choice for larger and more dynamic network environments.
