A network architecture employing two distinct layers to manage network traffic represents a simplified yet effective approach to Local Area Network (LAN) design. This structure commonly consists of a core layer, responsible for high-speed data transport, and an access layer, providing connectivity for end-user devices. Data flows efficiently between these two tiers, optimizing network performance in smaller to medium-sized environments. For instance, in a two-story office building, the core layer might reside on the first floor, interconnecting various departments, while the access layer is distributed across both floors, delivering network access to individual workstations.
This type of network organization offers several advantages, including ease of management and scalability. Its streamlined design simplifies troubleshooting and allows for easier expansion as network demands grow. Historically, it emerged as a cost-effective alternative to more complex, multi-layered architectures, particularly suitable for organizations where intricate segmentation and advanced features are not paramount. The reduced complexity translates to lower operational overhead and simplified network maintenance procedures.
