Understanding the problem

February 23, 2005 3

MPLS – what problem does it solve• Reduce complexity in core network nodes• Introduce flexible new routing services in the

network• New services or applications implemented in the

edge without modifying the core• Some of the new services that use MPLS−Virtual private networks (VPN)—many customers

securely over a shared core network− Legacy transports over a common network−Differentiated service levels− Traffic engineering—ability to direct where traffic goes

February 23, 2005 4

MPLS – what problem does it create• Provisioning can be complex• Hard to map from network problems to the

customer• Network performance needs to be mapped to

customer or service• Differentiated class of service introduce the need to

monitor service levels

OpenView TeMIP• Telco-grade fault management

application− Scalable and flexible — covers

the largest networks− Supports multiple overlapping

management− Access Modules provide two-

way communication with EMS or NE

OpenView Service Quality Manager• Collect KPIs from multiple

types of sources• Service level monitoring

− Are we currently operating as desired or expected

• Service compliance monitoring− Do we comply with

commitments? − Is there any SLA in jeopardy?

• Views and reports for a variety of users and needs− Both real time and historical

perspective

• Customer Care• Operations• Customers

Transport layer 1 device failure:• TeMIP receives alarm streams from fault

managers 1,2,3• TSM/Expert identifies root alarm at layer

1, a transport failure• TSM/Expert recognizes related

cascading alarms at layer 2,3• TSM/Expert reduce related alarms to

zero at layers 2, 3• Expert notifies Layer 2,3 NOCs of event

acknowledged at layer 1• Expert initiates trouble ticket at Layer 1

for failed transport device• Expert initiates trouble ticket for affected

priority service• Customer is pro-actively contacted with

information relative to service failure


Use cases: what if• TeMIP/TSM analyzes what services would be impacted if a layer 1

component is out of service− Components in the access network can be mapped to a customer− Components in the IP/MPLS core can be mapped to router or link failures

• RAMS can provide information on effects of router or link failure

Effect on path of onerouter failing

Effect on path of secondrouter failing


Use cases: service level management• Service level monitoring
