Introduction
Sample Network
1-10
The environment is assumed to be a three-tiered network in a large data center. The
first tier is core routers that provide connectivity to a campus or WAN. The second
tier has redundant distribution switches that distribute all data-center traffic between
the access switches; the access switches constitute the third tier of the network. All
LAN clients, back-end servers, and back-end filers connect to the access switches,
which are layer-2 bridges. Through the access switches and distribution switches,
LAN clients connect to all back-end servers/storage, to one another, and to the WAN.

back-end filers and servers
The sample network has redundant ARXes connected at each of the distribution
switches. Physically, this is a one-armed connection; conceptually, the ARX has
front-end clients in front of it and back-end servers and filers behind it. To simplify
