New World Requirements • Rapid invention of new services and technology • Intelligent applications and services cross traditional layers • Convergence of services and customer interfaces to services • De-monopolization (shorter system lifecycles, increased heterogeneity, more cross provider efforts) 1209 1044_05F9_c1

Why Not Prolong the Legacy OSS Architecture? • It is difficult to maintain consistency of data across disparate systems • Speed that new services can be brought to market is slowed by re-development of apps • Insertion of new technology and services is extremely costly • Fixed interactions limit ability to meet new market requirements and changes in regulations and/or business processes 1209 1044_05F9_c1

Legacy Architecture Also Limits Feature Differentiation • Consolidated view of services Single bill One contact number for trouble inquiry Catalog of all available services
• Customer “self-help” Customer ordering Web-based billing and status
• User personalization of services 1209 1044_05F9_c1

New World Operations Changing the Game Cisco Network Services/Active Directory (CNS/AD) Technology Provides Foundation Services
• Network elements, application services, and OSS systems are “directory-enabled” • Service and process logic is bound to directory
Directory Application

CNS/AD
• Directory manages “corporate-wide” info including data, data mapping, and process interaction 1209 1044_05F9_c1

New World OSS Components Directory Enabled Apps
4
• Applications use directory to determine service logic and location of data • Apps publish and subscribe information to and from the directory • Apps provide value on the service objects in a network independent way • Adapters allow communication between applications, workflow, and directory 1209 1044_05F9_c1

• Manages “hooks” identifying events that manage interactions • Executes and manages all process steps • Keeps knowledge of task completion status and error break-out conditions
Deterministic Processes Control Over Network Operations End-to-end 1209 1044_05F9_c1

9. Rep Uses Contact Info to Notify User Service Is Up
1. Administrator Adds New Employee
8. Service Is Checked
3. User Logs in to SP Via Web
4. User Enters Home Address
Order Status Is Updated CNS/AD
5. User Is Presented With Service Options 1209 1044_05F9_c1

Attributes of the New World OSS Architecture • Eliminate duplicate data entry • Provide uniformity across domains and technologies • Allow introduction of new services more quickly • Reduce customization costs and cost of upgrades • Improve marketing data • Reduce personnel interaction through direct customer interaction with OSS systems 1209 1044_05F9_c1
© 1999, Cisco Systems, Inc.

Real World Challenges
• Need to integrate with existing systems • Migration plan is necessary • Legacy applications should progress from CNS/AD unaware, to CNS/AD aware, and finally to CNS/AD enabled • While scalable and flexible, schemas, data partitioning, and directory network design is paramount to future success 1209 1044_05F9_c1
