4 IBM and Cisco LAN Switching: Interoperability and Migration Guide

Figure 3. Overlaying network

To avoid the cost of parallel trunks, customers may want to speed the

migration of boundary equipment to the newer technology.

1.1.4 Adding more levels to a hierarchy

As network size and traffic volumes increase, it may be desirable or required

to add more levels to the network. As an example, picture the network in

Figure 4 consisting of IBM ATM switch nodes 1, 2, 3, 4, 5, and 6 connected in

a mesh network. We wish to expand by:

1. Adding nodes 7, 8, 9, and 10.

2. Adding nodes 100, 200, 300 and 400 to increase bandwidth capacity of

the backbone to support new applications such as imaging.
