Fddi Network Topologies - 3Com corebuilder 3500 Implementation Manual

The term network topology refers to the ways that stations are
FDDI Network
Topologies interconnected within a network. An FDDI network topology may be
viewed at two distinct levels:

Ring of trees

Dual ring
Physical topology — A network's physical topology is defined by the
arrangement and interconnection of its nodes. The FDDI physical
topology is a ring of trees. See Figure 13.
Logical topology — A network's logical topology is defined by the
paths through which tokens and data flow in the network. The FDDI
logical topology is a dual ring. See Figure 14.
