ConfDMaking Network Elements Smarter
Data Model Driven• Rapid development• Avoid costs of stovepipe architecture• Auto-render management interfaces
On-Device Transactions• Transaction-safe• Reduce configuration errors and
network downtime• Not peek-and-poke
Built for Scale• Multi-box management• High availability• Role-based access control• Symmetric multicore processing

Customers expect fastTurn-up and spotless
Frequency of change in networks increasing
Complexity of service provisioning exploding
Industry Challenge
VoiceServices

MobileBackhaul
AccessServices
OPERATORS must replace manual, error-prone, time consuming steps
in service provisioning
NEPs are required to provide more complete operations solution
6
Current Approaches Ineffective
Manual• Configure one device at a time• Requires network experts• Expensive• Error-prone and not scalable
Vendor Specific EMS• Minimal automation functionality• CLI scripting or SNMP limitations• Error-prone • Not service-aware
Multi-vendor Tools• Multiple adapter layers• CLI scripting or SNMP limitations• Complex and hard to maintain• Error-prone

Examples of Carrier Ethernet Challenges
Customers expect fast turn-up and spotless service quality• Mobile operator• Financial institution interconnect• Private line replacements
Complexity of provisioning multiplied per service• 20-30 parameters per device• Minimum two devices per change• Lock-step provisioning (service, OAM)
Frequency of change in networks increasing• Thousands of CE elements• Tens of thousands of E-services• Service parameters

Implementation for Carrier Ethernet
• Complete Configuration Management System– Web UI based on common
practice– Service models based on MEF
7.1 (NMS/EMS)– Device models based on MEF
7.1 (EMS/NE)– Configuration database
• Reduce development time by 6+ months
• Reduce project risk• Reduce life time engineering
costs by 50%

Deployment Scenarios
EMS Deployment• Add to existing EMS
• Differentiate OAM Layer
• Fine-grained, real-time changes
OSS Deployment• Integrate with Service Assurance
• Reduce cost of adapter maintenance
• Accelerate service deployment
11
• New industry challenges to provision services effectively• Gaps in legacy approaches driving costs, delays, and
network disruptions• NCS is an innovative solution for building power
configuration management applications– Dynamic, model-driven, and adapter-free
• Growth and complexity of Carrier Ethernet driving NEPs to deliver comprehensive OAM solution
• Tail-f Systems makes activating Carrier Ethernet networks faster and easier
