Ethernet LAN Topologies

Given the benefits of structured wiring systems and the ability to support high-speed Ethernet connections, today’s Ethernet LANs are commonly deployed as a series of connected star-wired networks. The way in which organizations connect the stars (or other topologies) can greatly impact network performance. The topology is the physical configuration of the Ethernet network. Most organizations with more than a few network nodes use structured wiring systems interconnected via wiring closets and centrally located data centers. Centralizing network wiring provides several advantages. Bringing network connections into a single location provides network designers with several options. FIGURE 7-3 shows a centralized wiring ...
