Chapter 9. Token Ring and FDDI Network Review and Analysis

After a Token Ring or Fiber Distributed Data Interface (FDDI) network has been documented, the next step is to review the physical and logical topology for any performance-impacting issues.

NOTE

Token Ring and FDDI network review and analysis concepts are similar because they are both token passing, which means they are deterministic network technologies. This means that it is possible to calculate the maximum time that passes before a host is capable of transmitting, unlike contention-based networks, such as CSMA/CD networks (Ethernet is one example).

The physical topology review ensures that the standards and practices for Token Ring (IEEE 802.5) and FDDI (ANSI standard X3T9.5) networks, ...
