Reducing OpEx with Network Management• CapEx typically follows
the economy• OpEx is consistent
• Typical ratio of a Tier 1 carrierCapEx vs OpEx spending
• OpEx efficiencies have higherprofitability and a higher ARPU

applications
ApplicationsApplications
• MPLS LSP Ping (ICMP) for connectivity checks• MPLS LSP Traceroute for hop-by-hop fault localization• MPLS LSP Traceroute for path tracing
SolutionSolution
• Detect MPLS traffic black holes or misrouting• Isolate MPLS faults• Verify data plane against the control plane• Detect MTU of MPLS LSP paths

MPLS AToM Virtual CircuitConnection Verification ( VCCV)
• Draft-ietf-pwe3-vccv-xx.txtIETF StandardsIETF Standards
• Layer 2 transport over MPLSFRoMPLS, ATMoMPLS, EoMPLS
ApplicationsApplications
• AToM VCCV allows sending control packets in band of an AToMpseudowire. Two components:
Signaled component to communicate VCCV capabilities as partof VC labelSwitching component to cause the AToM VC payload to be treated as acontrol packet
Type 1: uses Protocol ID of AToM Control wordType 2: use MPLS router alert label
SolutionSolution
• Ability to provide end-to-end fault detection and diagnostics for anemulated pseudowire service
One tunnel can serve many pseudowires.MPLS LSP ping is sufficient to monitor the PSN tunnel (PE-PEconnectivity), but not VCs inside of tunnel

MPLS Traffic Engineering: AutoTunnel –Primary, Backup, & Mesh Groups
• draft-ietf-mpls-rsvp-lsp-fastreroute-03.txt• draft-ietf-ospf-cap-01.txt• draft-vasseur-mpls-ospf-te-cap-xx.txt
IETF StandardsIETF Standards
• MPLS VPN with multiservice SLAs (voice, video, and data sites)• MPLS AToM-based Layer 2 services with “Bandwidth Assurances”• Enhanced SLA service offerings with low packet loss during failure
condition – “Bandwidth Protection”
ApplicationsApplications
• Backup AutoTunnel—Enables a router to dynamically buildbackup tunnels
• Primary one-hop AutoTunnel—Enables a router to dynamicallycreate one-hop primary tunnels on all interfaces that have beenenabled with MPLS TE tunnels
• Mesh Group AutoTunnel – Enables automatic establishment of full-or partial-mesh of TE tunnels
SolutionSolution
• Ability to protect links and nodes with no requirement of “trafficengineering”
• Need to ease configuration of “increased bandwidth inventory”MPLS TE designs such as full mesh
