Connectrix v6.02 Planning Guide
Single-hop topology design is strongly encouraged. The isolation and
remediation of ISL congestion is far simpler when there is only one
hop between each domain. In Figure 4-14, if there were no ISLs
between Domains 1 and 3, twice the ISL bandwidth would be
consumed by routing the traffic through Domains 2 and 4. This traffic
would compete with traffic on Domains 2 and 4 and complicate
congestion analysis. Frame latency through the fabric is minimized
and availability is superior in a single-hop topology design.
