The Network Life Cycle by Loki Jorgenson

The Network Life Cycle defines a range of needs that require a variety of methodologies and tools for network Monitoring, Measurement, Assessment and Diagnosis (MMAD). Each stage of the NLC has its own requirements that can typically be met with a judicious selection of tools and assessment solutions. This guide provides some of the underpinnings of a successful NLC. 

Each stage of the typical Network Life Cycle requires some degree of attention with regards to MMAD. In fact, the degree to which each stage is properly carried out can define the likelihood of success of subsequent stages.

Network documentation

In order to respond to network incidents you will need to have thorough records. These resources will help.

Network monitoring

Keeping a close eye on your network performance and throughput is critical. But as your network grows and becomes more complicated, monitoring it becomes all the more complex. Here's some help.

Network measurement

Measuring performance (not just availability) is essential. Use these resources as a starting point.

Network troubleshooting

Troubleshooting your network is a big part of a network manager's job. It's also one of the most complex parts. These resources can help you with the many options and all those details.
