ATOMIC-2 LAN Topology

This topology is designed so that each user machine has at least two independent paths to the gateway (center, light blue). The wiring also maximizes the number of connected machines and minimizes the hopcount.

• Light blue: "gateway" to ATM
• Magenta: singly-connected Lab switch (can be isolated/dashed line)
• Red: doubly-connected host switches ("tie-links")
• Blue: triply-connected host switches ("backbone")
• Green: user and lab hosts (6*6 + 4*5 = 56 user hosts, 7 lab hosts)
