Network Design for a Dial NMS Case Study

Basic Dial NMS Implementation Guide
•
All remote modem users share a common pool of modem resources. Users can dial in to either POP.
•
The dial POPs are redundant. If one POP loses service, traffic is re-routed to the other POP.
Describing how traffic is re-routed is outside the scope of this case study, and the diagrams in the
case study show simplified IP paths only.
THEnet uses this model to identify the different functional areas of the dial NMS:
F = Fault management
C = Configuration management
A = Accounting management
P = Performance management
S = Security management
A dial NMS provides the FCAPS management functions for a DIAS.
Benefits of a Dial NMS
A dial NMS:
•
Increases network availability
•
Improves end-user satisfaction by improving service performance
•
Provides fault-isolation capabilities, which improves fault-analysis information
•
Reduces network support costs
•
Enables capacity plannning
•
Enables security improvements
•
Provides accounting (for example, billing and chargeback)
•
Processes important connection events and alarms for statistical analysis
•
Provides performance-reporting capabilities for a dial Internet access service
•
Enables standardized software releases (for example, software versions and configuration files)
•
Addresses the perception problems that are commonly associated with dial access networks
