Service Assurance and Provisioning for IP Networks Craig B. Ginsberg Consultant Internet Services Business Unit APAC

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

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 Lucent Technologies - Proprietary 3

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 Lucent Technologies - Proprietary 4

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 • Qo. S is now the most important issue …We need to…. – – Provision it Manage it Measure it Bill for it • The result … ‘Service Level Agreement’ Lucent Technologies - Proprietary 5

Business Value • Cost savings due to reduction in manual work Leased Line, Frame Relay Services Provisioning, x. DSL 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 Lucent Technologies - Proprietary 35

Customer value • A flow-through provisioning architecture integrating ATM, SONET, SDH, IP and x. DSL 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 Ø Increasing customer satisfaction resulting in retention and increased orders from existing customers. Ø Ability to meet market demand ahead of competitors • Reduces training and operations costs by hiding complexity from the user. Lucent Technologies - Proprietary 36

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 Qo. S through Provisioning and Service Assurance Lucent Technologies - Proprietary 37
