Overview of Line Protocols The PHY standard defines the rules for encoding and framing data for transmission clocking requirements and line states The MAC standard defines the FDDI timed token protocol frame and token construction and transmission on the FDDI ring and ring initialization and fault isolation The SMT standard defines the protocols for managing the PMD the PHY and the MAC components of FDDI The SMT protocols monitor and control the activity of each node on the ring Figure 1 5 shows the relationship of the four FDDI standards Media Access Control MAC Station Physical Layer Protocol PHY Management SMT Physical Layer Medium Dependent PMD Figure 1 5 Relationship of FDDI Standards FDDI Dual Counter Rotating Ring Architecture FDDI LANs comprise two independent counter rotating rings a primary ring and a secondary ring Data flows in opposite directions on the rings Both rings can carry data however in high bandwidth applications Bay Networks specifies that the primary ring transmits data and the secondary ring is a backup device The counter rotating ring architecture prevents data loss in the event of a link failure a node failure or the failure of both the primary and secondary links between any two nodes as follows e Ifa link on the primary ring fails the secondary ring transmits the data e Ifa node or corresponding links on both the primary and secondary rings fail one ring
