Network management models

Distributed (component)
Distributed network management is the default management model for network equipment. As
Figure 66: Tools for distributed network management
shows, each device is managed
separately, and can have its own management interface. There is no commonality between
these interfaces. Some might be CLI-based, Web-based, or GUI-based applications. In
addition, third-party tools such as MRTG complement integrated management interfaces to
provide additional functionality.

The advantage to this model is that the cost of tools is low compared to the centralized model.
Many of the tools are included with the purchase of networking equipment, and many are open
source. Also, many of these tools are more specialized on a specific platform or task than
centralized management tools. Most Avaya Integrated management products, including Avaya
VoIP Monitoring Manager, fall into this category.
There are numerous disadvantages to this model. First, this model requires more support
personnel than the centralized model. Next, there are numerous interfaces that support staff
must learn, which greatly increases training costs. Finally, the support person must check many
places to get the full status of the network, which adds time and the likelihood of missing critical
data. This model is appropriate in small to medium-sized enterprises with relatively few pieces
of network equipment. It is not appropriate for most large enterprises or enterprises with
complicated networks.
