1. 1 Pertemuan 09 Model Fungsional Matakuliah: H0372/Manajemen Jaringan Tahun: 2005 Versi: 1/0

2. 2 Learning Outcomes Pada akhir pertemuan ini, diharapkan mahasiswa akan mampu : Menyediakan implementasi model Fungsional melalui SNMP

3. 3 Outline Materi Aspek Fault Management Aspek Configuration Management Aspek Performancet Management

4. 4 Functional Model No formal specs of functions in SNMPv1 OSI model addresses –configuration –fault –performance –security –accounting

5. 5 Network & Systems Management Networked Information Systems Business Management Service Management Network Management System Management Element Management Resource Management Network Elements System Resources

6. 6 Management Applications OSI Model Configuration Fault Performance Security Accounting Reports Service Level Management Policy-based management

7. 7 Configuration Management Network Provisioning Inventory Management Equipment Facilities Network Topology Database Considerations

8. 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. 9 Performance Management Tools Performance Metrics Data Monitoring Problem Isolation Performance Statistics Tools: Protocol analyzers RMON MRTG

10. 10 Performance Metrics Macro-level Throughput Response time Availability Reliability Micro-level Bandwidth Utilization Error rate Peak load Average load

11. 11 Performance Statistics Traffic statistics Error statistics Used in QoS tracking Performance tuning Validation of SLA Trend analysis Facility planning Functional accounting

12. 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. 13 Accounting Management Least developed Usage of resources Hidden cost of IT usage (libraries) Functional accounting Business application

14. 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
