Planning Your Network
Before installing your ATM devices you should spend
some time planning your network structure. This
section lists some of the points you should consider.
■
Are routes defined within your ATM network
so that your ATM devices can connect to your
LAN Emulation services?
Examine your existing network topology and
decide if further configuration is required. In
particular, you should consider the location of your
LAN Emulation services.
■
Does your existing ATM network have
sufficient resources?
Consider the capacity of:
■
Your ATM Switches, and the number of
additional connections your ATM device requires.
■
Your LAN Emulation services, and the number
of additional
LAN Emulation Clients (LECs) your
ATM edge-device will attempt to join.
■
Can your ATM devices communicate with each
other?
■
Ensure that all of your ATM equipment is using
the same line framing and signalling protocols.
■
Ensure that all inter-switch routes are configured
correctly.
■
How do you intend to manage the ATM
network?
Can the network manager communicate with the
ATM devices you wish to manage? Check the
routing tables.
