Understanding Maintenance Methods: This section discusses the importance of
proactive maintenance tasks, as opposed to reactive maintenance, required to address a
problem in a network. Also discussed in this section is a collection of commonly used
maintenance approaches.
Identifying Common Maintenance Procedures: This section lists common
maintenance tasks, emphasizes the importance of regularly scheduled maintenance, and
summarizes critical areas of network performance.
The Network Maintenance Toolkit: This section identifies how to compile a set of
network maintenance tools that complement your network maintenance plan.
Business operations are becoming increasingly dependent upon the reliable operation of
business data networks (which might also carry voice and video traffic). A structured and
systematic maintenance approach significantly contributes to the uptime for such networks.
Consider the purchase of a new car. Many excited owners of a new car peruse the owner’s
manual to find the recommended maintenance schedule and vow to perform the routine
recommended maintenance. They instinctively know that adhering to a documented
maintenance plan can reduce the occurrence of issues with their car. Similarly, the number
of issues in a network can be reduced by following a documented schedule of maintenance.
This chapter discusses the importance of having a maintenance plan and introduces several
popular models that can be adapted to your network. Next, you are introduced to specific
maintenance tasks. Finally in this chapter, you identify the tools (for example, network
monitoring and disaster recovery tools) you need in your virtual toolbox.
