FDDINetwork Topologies 7
FDDI networks can be arranged in a variety of ways, depending on the
placement of stations (SAS and DAS) and the use of concentrators (SAC and
DAC). The optimum arrangement for a particular installation is dependent on
several factors, including:
•Cost
•Network size
•Required Bandwidth
•Typeof network traffic
•Fault resistance and network reliability
This chapter describes some of the common FDDI network topologies and
discusses the primary advantages and disadvantages of each.
