Customers’ operational expenses can reach up to 45% of their overall expenditures and are a major factor in their decision in granting business to network hardware providers – many deals are lost due to Operations and OSS/NMS issues

TMF’s TOM/eTOM, NGOSS

DMTF’s WBEM

Microsoft’s DCOM


Major NMS/OSS Protocols

• NMS/OSS specifies a set of standardized protocols that create a architecture used for monitoring and management of SPs networks, services and customers.


Example of the Standard Technologies Used in NMS/OSS

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.


What does eTOM Do?

•Service Providers are pushing for a common eTOM industry framework that:Broadens TOM to a total enterprise modelReflects the increased complexity in service provider business

relationshipsEvolves processes to support convergence of information and

communications services and technologies

Example Fault Managment


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 ?


Fault Management

• [ISO Definition] Handling errors, faults and alarms in a timely and controlled manner.

Error: Deviation of system from normal operationsFault: Physical or algorithmic cause of a malfunctionAlarm: 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


“What tools do I need if I get 30 traps per sec sustained on my network?”


Source : One2One NOC Manager

“A pen to write my resignation.”


Sources

• Routers, switches, wires, fiber, PDUs, DNS servers, HVACs, power companies, squirrels, flooding, soft drinks, clumsy people, nuclear accelerators, bulldozers, users, network managers,…


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

Promiscuous Registration Mode

• Only the modem is registered• CPEs receive service based on the modem they are behind

(prov vs. unprov)• Modem can be restricted to a provisioning group (otherwise

goes back to unprov)• Can be system wide or per Cable Modem basis
