Enhanced TOM (eTOM)
•eTom:
Is a business process framework based on TOM.
Provides enterprise processes required for an SP.
Is the key component of the NGOSS business view.
Enables SPs for the development of process automation solutions for their organizations.
323232© 2003 Cisco Systems, Inc. All rights reserved.Presentation_ID
What does eTOM Do?
•Service Providers are pushing for a common eTOM industry framework that:
Broadens TOM to a total enterprise model
Reflects the increased complexity in service provider business relationships
Evolves processes to support convergence of information and communications services and technologies

Example Fault Managment
444444© 2003 Cisco Systems, Inc. All rights reserved.Presentation_ID
Why do we need fault management ?
• To monitor the network and know what’s going on ?
• To identify the root cause of network faults ?
• To measure downtime (uptime) ?
• To meet SLA’s ?
• Because everybody else does it ?
• Because I’ve been told it’s important ?
454545© 2003 Cisco Systems, Inc. All rights reserved.Presentation_ID
Fault Management
• [ISO Definition] Handling errors, faults and alarms in a timely and controlled manner.
Error: Deviation of system from normal operations
Fault: Physical or algorithmic cause of a malfunction
Alarm: Notification of a specific event, may or may not represent an error
• A fault is an unplanned failure of software, hardware, or wetware
• Not every outage is due to a fault
• Not every fault results in an outage

Fault Management Needs
• Keep me out of trouble!– Let me know when I’m having a problem or about to have a problem
• Support my growing Cisco network as one ‘system’– Routed and switched environment
– IP telephony – call managers, phones, etc.
– Network connectivity analysis
• Don’t make me add more staff– Out-of-the-box with no rules to write
– Support new devices in a timely manner
• Fit into my present mode of operations (PMO)– DFM, ITEM, CIC, HP OV, Tivoli, Micromuse, SMARTS, etc.

Network Connectivity Monitor
• Automated network connectivity and impact analysis for networks based on Cisco® products and technologies
• Consolidation and integration of CiscoWorks NCM, DFM, or ITEM fault and operational health analysis
• Focused on users taking corrective action
• Integration with user’s present mode of operations, including multivendor MoMs: HP OpenView, Tivoli NetView, Cisco Info Center, SMARTS InCharge, etc.
• Regular incremental device support for new Cisco devices
