Milan Technology MIL-S1000 - Manual (Page 26)

Collapsed Backbone Link
Traditionally, bridges and routers have been used to link
local area networks into one interconnected network. But
these devices involve difficult management and long traffic
delays.
The MIL-S1000 providers multiport bridges with short
delays, easy setup and maintenance, making it ideal for
backbone links. Also, the Built-in filtering on this hub
deceases network traffic, while the multiple ports that
communicate simultaneously increases network
performance.
One or more of your hub's 100Mbps or 1000Mbps ports
can be used as a high-speed backbone link to other hubs
serving as collapsed backbones.
