Campus Network Architecture
Why do we use Hierarchical LAN Design Models ? We divide the network architecture into modular layers so that we can achieve the following, Each Layer implements and performs a specific function Helps the network to scale easily Provides Fault isolation and facilitates easier troubleshooting Modular Building Blocks: Hierarchical LAN Design breaks the network into 3 building blocks: Access Layer Distribution Layer Core Layer Campus Network Architecture: The Access Layer Access Layer AKA the “Network Edge” it’s the block where the end user devices are attached. End User Devices – PC’s, IP Phones, Wireless Access Points, Printers, IP Cameras .. etc. Provides high bandwidth access to both wired and wireless users, Since it’s the First hop for Quality of Service (QOS) trust points. Access Layer can be logically segment using VLANs, where we can have different logical networks for performance, management and security Communication between the Access Blocks occurs...
