Chapter 1. Planning interoperability and migration 5
By inserting an additional hierarchy of faster backbone switches, as shown in
Figure 5, network topology is simplified and enabled for growth. Higher level
functions will then have access to the faster backbone and can grow as
needed.

1.2 Network management
Management of the network is a major consideration when choosing a
strategy and selecting vendors. This redbook deals with the aspects of
migrating switching hardware, and detailed considerations regarding
management software products are beyond its scope. We do, however,
contribute a few general thoughts.
Ideally, only a single management platform should be necessary to manage
all information technology resources, including the network. In reality, such a
platform hardly exists, but the product suite from Tivoli Systems Inc., an IBM
company, constitutes a good attempt to deliver comprehensive support.
Tivoli NetView acts as host for CiscoWorks2000 as well as for IBM Nways
Manager for operation management and automation. Tivoli Enterprise for
asset and change management likewise provides integration with both of
these element managers.
