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

• Number of alarms can grow exponentially
• Lower-level causes are not always obvious

•Acknowledge Root Alarm•Initiate Device Tests•Initiate Repair Process
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
February 23, 2005 28
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
