OpenView Network Node Manager: Designing and Implementing an Enterprise Solution

Introduction

For small networks a single Network Node Manager (NNM) system may suffice, but large, multisite worldwide networks will need many NNM systems. A formal project plan is needed for larger implementations to ensure a successful deployment. This plan must cover the following aspects of network management:

• A requirements analysis is best performed early in the project because of the obvious downstream impact that occurs should the rate of change of the requirements exceed the rate of engineering. The requirements analysis explores the number of NNM systems to be deployed, how many active users are expected, what transaction response times are acceptable, the number and kinds of maps users will need, what reports are needed, what devices ...
