Description: A table that contains information linking

physical backplane allocation to logical

networks. This information is useful:

(1) to determine the physical allocation

of networks on the backplane, and

(2) to determine the remaining capacity of

the backplane for future network growth.

Since unknown modules are managed via dip

switches, this is useful in order to set the

dips to the appropriate settings.

Ethernet is a bus architecture. Once a path is

allocated, all modules and ports can access that

path.

Token Ring and FDDI are ring architectures.

Each module on a ring requires a path. Therefore,

4 paths could be used to link 4 modules together

on one ring, or 2 modules on 2 separate rings.

It is possible to have a module allocated to

a ring (and thus a data path) without linking

to another module.

These rules can be used to determine the remaining

capacity for network growth.
