  1. Service Assurance and Provisioningfor IP Networks Craig B. Ginsberg Consultant Internet Services Business Unit APAC

  2. Agenda • Definitions • Where are we going with IP? • Why is service assurance so important in today’s world? • The provisioning challenge ...domain, domain, domain • The importance of software in the network • The SA solution, examples and value • Service provisioning challenges, examples and value • Conclusion

  3. Service Assurance Definitions • Service Assurance - Maintaining the service The timely response to and resolution of customer or network triggered problems, tracking, reporting, managing and taking action to improve performance for all aspects of a service • Fault mgmt • Sectionalization • Root cause analysis • Performance monitoring and alerting • Traffic trending • Congestion alerting • Trouble ticketing • Congestion control • Links to provisioning • Resulting in a high Quality of Service

  4. Service Provisioning • Service Provisioning - Installing the service The flow through process involved in the installation, configuration and activation of a service across multiple technologies and equipment providers to provide an end-to-end service. This includes • Order Management • Workflow Management • Multi-domain activation • Multi-technology activation • Resulting in a fully automated provisioning process

  5. Reality Check - the IP world • The world has changed forever • Traditional methods of managing and provisioning networks no longer apply • Best effort is NOT good enough • QoS is now the most important issue …We need to…. • Provision it • Manage it • Measure it • Bill for it • The result … ‘Service Level Agreement’

  9. Traditional Networks Switch Network Physical Network Access Network “Single networks” that rely on circuit switched technologies over TDM infrastructure Inter-Office Network

  10. Today's Networks Switch Network IP Services ATM Network DWDM/SDH Network Physical Network Access Network “Networks of Networks” that Layer the Technologies and Services. Each technology can be supplied by multiple vendors each needing provisioning and management Inter-Office Network • Multi-Managed: • Global Management Centers • Legacy Systems • Carrier Interfaces • Multi-Vendor:Equipment, Facilities; Logical components • Multi-Service: POTS, ISDN, Data Services, Frame Relay, VTOA, VOIP • Multi-Technology:DWDM, ADSL, TDMA, CDMA • SONET, SDH,ATM, IP, Gig-E

  11. Service Assurance Challenges • Support Management across multiple vendors and technologies • Need to be able to measure and act pro-actively using thresholds • Best effort is NOT good enough …….QoS becomes much more important ! QoS now relates to • Network throughput/latency • Congestion • CPU utilization • The challenge is to meet QoS NOT by Over Engineering BUT by Pro-active management

  12. Industry direction is challenging operators Management and Operations Challenges Next Generation Networks Service Provider Directions Industry Drivers Operations Challenges • High Speed Access • Data Equipment Proliferation • Architectural Convergence • Architectural Transition • One Stop Service Shopping • Service Differentiation • QoS Based Services • Service Level Agreements • Carrier InterNetworking • Network Partitioning • InterDomain & Multi-Vendor Management • “Monitorable” QoS & Customer Service Mgmt. • Convergent Solutions for Multiple traffic types • Single seat integration • Automated Service restoration • Centralized and distributed provisioning, • Plus: Reduce Cost/Intervals • Improve Quality • Correlation of many alarms (very important)

  13. Importance of software Resulting Impact Cost of operations Market Forces are driving need for assurance of new applications and technology Complexity • Network complexity increases with implementation of new technology & services • Life cycle costs are shifting from initial investment to cost of operations SOFTWARE IS KEY TO “HARNESSING THE POWER & COMPLEXITY OF THE NETWORK” • Software will differentiate competitive networks • Software is critical to effective management of resulting operations environments • Software is the catalyst for achieving “break-through” improvements in operations • Software is critical to provisioning across multiple domains and technologies

  14. The Shewhart P-D-C-A Quality Cycle 1-Plan 4-Act Service Fulfillment Service Assurance 3-Check 2-Do

  15. Service Assurance software can help Network Complexity Business • Reduce Mean Time To Repair • Protect and Maximize Revenue • Squeeze the most out of existing investment • Detect & Sectionalize Network Troubles • Network Interconnect • Congestion • Logical and Physical Errors • Allow Diverse Equipment & Technologies • Correlate many alarms Service Assurance Customer Centralization & Consolidation • Maximize Bandwidth Available • Enable Appropriate QoS • Monitor & Report Service Results • Improve Operation Efficiency • Integrate Operations • Drive Quality Improvements • Optimize Staff, Training

  24. Value to Customers • Meet future Network Management needs as carriers evolve to Multiple Service Networks • Network troubles are quickly identified and corrected • Proactive resolution of faults • Manage complex networks comprised of diverse technologies • Scalable from a few to thousands of Network Elements • Easy to use, configure and flexible • Provide maximum system availability • Optimize reliability and capacity of multi-service network

  25. Service Provisioning

  26. Service Provisioning • The challenges service providers are facing in the management of their networks arise from at least two different sources: the need to weave a number of technologies into a seamless network and the need to integrate a multiplicity of systems required managing the technologies. • True Inter-Domain Configuration Management will enable service providers to perform flow through end to end provisioning across all technologies including: - • PDH • SDH • DWDM • SONET • ATM/FR • xDSL • IP.

  27. Requirements • Industry is at a cross road • Operators moving from circuit switch technology to packet switched………..plus……. • Rolling out a terrestrial Multi-service networks to support • WAP, UMTS, Location based services, VAS • Intranet/Extranet services • Traditional voice/fax, Data services • IP, VoIP,VoATM • IN services, Video • Data • etc…etc…etc

  28. Requirements Cont • Ability to support designing, activating, and managing network services across their multivendor, multi-class, and multi-technologies communication networks. • Single Point Of Data Entry, Automated Provisioning, Web Based, Published CORBA API. • Flow-through of network & service orders from order management System to Domain Management System. • Integrated end-to-end service design and activation. • Support end-to-end service design view and logical hierarchy of facilities supporting the services.

  29. What do we mean ? Examples: • 3G IP data service on UMTS • IP data service via WAP or intranet/extranet • SDH and ATM • Complete picture end-to-end software and hardware technologies - data service PVC across multiple domains and technologies

  35. Business Value • Cost savings due to reduction in manual work Leased Line, Frame Relay Services Provisioning, xDSL subscription. • Additional revenue due to earlier turn-up of service • Cost savings due to reduction in manual work in Facility Design and Implementation • Cost savings due to reduction in manual work in ATM-over-SONET Infrastructure Provisioning • Higher customer satisfaction leading to increased market share and reduction of churn • Ability to meet market demand ahead of competitors • Reduction in training costs

  36. Customer value • A flow-through provisioning architecture integrating ATM, SONET, SDH, IP and xDSL technology domains. • Mechanization of network and service design and inventory management tasks leading to large savings in operations costs • Revenue stream for newly-provisioned services begins sooner because of a faster turn-up (provision takes minutes verses weeks). • Increase in market share due to • Increasing customer satisfaction resulting in retention and increased orders from existing customers. • Ability to meet market demand ahead of competitors • Reduces training and operations costs by hiding complexity from the user.

  37. Conclusion • Biggest OSS challenge to carriers is managing across multiple technologies and domains • Provisioning must be able to support new technologies from a common Order Management and Provisioning engine • The management of networks can no longer be based on traditional best effort methods • Service assurance is about combining fault and performance management. • Quality of Service is now the most important issue in the IP world • You can only guarantee Service Levels if you can proactively manage your QoS through Provisioning and Service Assurance
