Considerations
for
Multisegmented
Networks The 100BASE-T technology defined in the IEEE 802.3 standard provides for both
homogeneous CSMA/CD 100 Mbps networks and heterogeneous 10/100 Mbps
mixed networks. Both network topologies can be supported by connecting
various LAN segments using repeaters and switches, bridges, or routers.
The LinkBuilder FMS 100-TX Hub supports only the 100 Mbps network
topology. Access to 10 Mbps functionality is possible through connections
with switches, bridges, or routers that support 10/100 Mbps topologies.
Two LAN segments connected by a repeater constitute a single collision
domain. LAN segments connected by switches, bridges, or routers constitute
multiple collision domains. You can achieve maximum network flexibility by
designing multiple collision domain networks.
For example, a combined system containing both 10BASE-T and 100BASE-T
devices and built with repeaters and switches can deliver dedicated 100 Mbps,
shared 100 Mbps, dedicated 10 Mbps, and shared 10 Mbps services to devices
on the LAN. Figure 3-7 illustrates a network composed of two collision domains
connected by a 10/100 Mbps switching hub.
