Network maintenance model
1.
FCAPS:
è
It stands for fault management, configuration
management, accounting management, performance management and security
management.
Fault Management: Use network management
software to collect information from routers and switches. Send an e-mail alert
when processor utilization or bandwidth utilization exceeds a threshold of 80
percent. Respond to incoming trouble tickets from the help desk.
Configuration management: Require logging
of any changes made to network hardware or software configurations. Implement a
change management system to alert relevant personnel of planned network
changes.
Accounting Management: Invoice IP telephony
users for their long-distance and international calls. Keeping track of what is
being done on the network and when it is being done.
Performance management: Monitor network
performance metrics for both LAN and WAN links. Deploy appropriate quality
service (QoS) solutions to make the most efficient use of relatively limited
WAN bandwidth, while prioritizing mission-critical traffic.
Security Management: Deploy firewall,
virtual private network and intrusion prevention system(IPS) technologies to
defend against malicious traffic. Create a security policy dictating rules of
acceptable network use. Use an authorization, authentication and accounting
(AAA) server to validate user credential, assign appropriate user privileges
and log user activity.
è
It defined by ISO.

ITIL
è
IT infrastructure library defines a collection
of best practice recommendation that work together to meet IT business
management goals.

CISCO lifecycle service
The cisco lifecycle services maintenance
model defines distinct phases in the life of a cisco technology in a network.
These phases are prepare, plan, design, implement, operate, and optimize. As a
result, the cisco lifecycle services model is often referred as the PPDIOO model.
