Access Layer Network Architecture Diagram - Enterprise LAN Design #3400998 (License: Personal Use)

This diagram illustrates the access layer of a structured cabling and network architecture, featuring three Ethernet switches interconnected at the top, each serving multiple IP telephony endpoints and workstations below. The red oval highlights the access tier, emphasizing its role as the entry point for end devices into the network infrastructure. Each device connects via dedicated links, supporting VLAN segmentation and QoS policies typical in modern converged networks.

Used in networking training materials, Cisco/ Juniper certification study guides, enterprise IT documentation, and vendor whitepapers to explain hierarchical network design (core-distribution-access model). Matches user intent for understanding physical/logical topology, switch port allocation, or VoIP deployment planning.
