Segmenting Hubs - D-Link DFE-2600 Series User Manual

Segmenting Hubs

Switching hub technology has made it more common to segment local area
networks into smaller pieces to reduce congestion. Segmenting makes it
easier to balance network loads, since a smaller number compete for the
bandwidth available.
A hub stack makes network management convenient, but too many stations
on a single network segment may give slow response at peak network loads.
Therefore, this hub series provides a way to segment hubs from the stack
into their own collision domains. Segmenting hubs can be accomplished
with a simple management command and does not require any hardware or
wiring changes.
Though the hubs continue to be cascaded together and are managed as a
single unit, each hub can either be a part of the collision domain of the rest
of the stack, or can be separated into its own network segment. These sepa-
rate segments can be bridged by connecting them through a compatible
switching hub.
The figure above shows an unsegmented hub stack. All hubs in the stack
are in the same collision domain because they are connected together
through the daisy-chain ports.
