Management Applications

• OSI Model • Configuration• Fault• Performance• Security• Accounting

• Reports• Service Level Management• Policy-based management

7

Configuration Management

• Network Provisioning• Inventory Management• Equipment • Facilities

• Network Topology• Database Considerations

8

Fault Management

• Fault is a failure of a network component• Results in loss of connectivity• Fault management involves:• Fault detection• Polling• Traps: linkDown, egpNeighborLoss

• Fault location• Detect all components failed and trace down the tree topology to the source• Fault isolation by network and SNMP tools• Use artificial intelligence / correlation techniques

• Restoration of service• Identification of root cause of the problem• Problem resolution

9

Performance Management

• Tools

• Performance Metrics

• Data Monitoring

• Problem Isolation

• Performance Statistics

• Tools:• Protocol analyzers• RMON• MRTG

10

Performance Metrics

• Macro-level• Throughput• Response time• Availability• Reliability

• Micro-level• Bandwidth• Utilization• Error rate• Peak load• Average load

11

Performance Statistics

• Traffic statistics• Error statistics• Used in• QoS tracking• Performance tuning • Validation of SLA• Trend analysis• Facility planning• Functional accounting

12

Security Management

• Security threats• Policies and Procedures• Resources to prevent security breaches• Firewalls• Cryptography• Authentication and Authorization• Client/Server authentication system• Message transfer security• Network protection security

13

Accounting Management

• Least developed • Usage of resources• Hidden cost of IT usage (libraries)• Functional accounting• Business application

14

Service Level Management

• SLA management of service equivalent to QoS of network

• SLA defines• Identification of services and characteristics• Negotiation of SLA• Deployment of agents to monitor and control• Generation of reports

• SLA characteristics• Service parameters• Service levels• Component parameters• Component-to-service mappings
