2.6 Compare Cisco Wireless Architectures and AP modes
Cisco wireless architectures refer to the design and deployment of wireless networks using Cisco wireless technology. There are two main wireless architectures used by Cisco: Centralized and Distributed.
1. Centralized Architecture:
In a centralized architecture, wireless access points (APs) are centrally managed and controlled by a single wireless controller. The controller is responsible for managing wireless security, quality of service (QoS), and roaming for all connected APs.
Advantages: Easy to manage, provides a centralized view of the network, and supports high-density deployments.
Disadvantages: Relies on a single point of failure (the controller), and may not be scalable for large-scale deployments.
2. Distributed Architecture:
In a distributed architecture, APs are deployed independently and do not rely on a central controller. Each AP is responsible for managing its own wireless security, QoS, and roaming.
Advantages: Supports high availability and scalability, and provides greater flexibility for deploying APs in remote locations.
Disadvantages: More difficult to manage, as each AP must be configured individually, and may require additional hardware for managing security and QoS.
