|The Network Life Cycle by Loki Jorgenson||Return to Table of Contents|
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.
