Chapter 18. Network Management Basics

This chapter covers the following topics:

• FCAPS Model

• Network Management Architecture

• Network Management Protocols

• An Introduction to TMN

Network management describes the methodology used to manage and maintain network operations and respond to user requirement changes. With the implementation of Simple Network Management Protocol (SNMP), local area network (LAN) and wide area network (WAN) components can be monitored and managed, often from what is called a central Network Operations Center (NOC) facility. The network management platform is an integrated suite of functions that can be implemented on one machine, or it can be implemented on several machines or databases spanning thousands of miles, supporting several organizations. Some examples of a network management platform are HP Openview or CiscoWorks 2000.

Network management can be segmented into two categories:

• Tactical Tactical network management relates to proactive and reactive situations, such as network failures, congestion, and unacceptable service quality. The tasks include troubleshooting, configuration, and adjusting traffic flows.

• Strategic Strategic network management involves a long-term perspective that is oriented toward adequate planning to avoid shortages as the network grows. Strategic tasks use information to adjust operations, optimize quality, and manage facilities to reduce overall operational costs.

This chapter discusses network management models that are both tactical and strategic. This includes a discussion of the following:

• FCAPS model

• Network management architecture

• Network management protocols

• Telecommunications Management Network (TMN)
