  1. Network Based IP Services Horace Lau Senior Market Development Manager Lucent Technologies, INS IP Services Business Unit

  2. Public IP Services; Not The Internet • The road to profits is in Public IP ServicesNetworks • A best-effort Internet doesn’t deliver service provider profits • Profits continue in classic data networks because they deliver quality service • But…the Internet delivered some great successes • Infrastructure for common communications: The TCP/IP protocol • Infrastructure for applications: Browsers, Streaming Media Formats, Email, Messaging, Directories • Today, customers require the service richness of the Internet with the service quality of the classic data networks

  3. Value-added IP Services Deliver Competitive Advantage Bandwidth-Managed Services IP VPNs Managed Security Business Internet Access Converged Services Content Management/ Acceleration Wholesale Subscriber Management Commodity Services Commodity Services Margin % Access Services Value-added Services Core Backbone Services

  4. Best Effort Internet Wireless PSTN Data Services Optical Core Service Providers Need Business Quality IP Services Network • Services • Connectivity • Performance • Reliability • Security • Simplicity • Affordability • Flexibility • Scalability • Ubiquity Public IP Network Investment in public data network infrastructure will grow from $12B in 1999 to $22B in 2003. (IDC) Broadband Access

  5. IP Is the New Public UNI(Network Connection) • Public IP Networks Require • Routing functions on the edge • Consistent interface to subscriber applications • Application-Aware Dynamic Service Delivery • End-End Across The Network • Network Changes Behavior As Necessary • Public IP Networks Must Provide • Application-aware priority for IP flows • Application specific behavior for different IP Flows • Deliver bandwidth, and access privileges as required • Per application • Dynamic signaling to support application requirements • Deliver services where and when they are needed • By requesting them from smart network elements • Public IP Networks Cannot Use a Hop-by-Hop Internet Architecture • Routers alone won’t support what needs to be done

  6. Deterministic ServiceBehavior • Service-specific functions in virtual routers • Traffic classification • Voice, video, data • Marking, shaping, policing • Priority queuing of IP application traffic • Voice first, then file transfer data packets • Mapping IP application traffic to MPLS paths • To ensure service quality • Pre-engineered traffic paths in core • Supports MPLS paths in: • Frame based networks (core router-based networks) • ATM multi-service networks • Provides: bandwidth guarantees, latency commitments • Provides: QoS

  8. Network Architecture forPublic IP Services Key Architecture Elements • Service Intelligence to build end-to-end services • Virtual Routing • Intelligent Agents • Service Creation Model • MPLS to create dynamic connections in and between layers in the network • Unified network managementfor provisioning, monitoring, fault recovery • Professional services for full public network design and lifecycle management expertise

  9. Access Network Complete Service Intelligent Architecture Service Intelligence • Recognizes users & their applications • Understands their individual service needs • Mediates on their behalf to deliver IP services • Regardless of when, where, or how they arrive on the network • All in a reliable and end-to-end, secure manner Scalable on-ramp for IP service traffic Actively mediates network behavior Reliable, high-speed, transport Metro Optical Intranet RAS IP/ATMCore Switch DSL Extranet IP/ATMCore Switch Optical Core IP Service Switch Cable Web IP/ATM Core Switch ISP Frame/ATM ASP Wireless Access Layer Core Layer Services Layer Intelligent, dynamic, scalable.

  10. MPLS for Dynamic ConnectionsIn & Between Layers • MPLS is an integral architecture element for communication in and between the network layers • Multi-Protocol Label Switching (MPLS) is not only used for traffic engineering in IP Networks • A Fundamental framework for Service Intelligence in Public IP Services networks • Benefit: Creation of highly customized services based on subscriber, application, and network requirements

  11. BSTDX PSAX Family GX550 MPLS for Dynamic Connections:within the IP & ATM Transport Layers • Multiservice ATM Core delivers infrastructure for Frame Relay, DSL, ATM Access and Multiservice MPLS • IP Core provides infrastructure for “pure IP” networks and Packet MPLS • MPLS between architectures provides for end-to-end IP services ATM Multiservice/ MPLS MPLS Signaling NX NX NX IP Switching/ Packet MPLS

  12. IP/ATM Core Optical Core MPLS for Dynamic Connections: Between Layer 1 and Layer 2 The service intelligent network requests bandwidth and transport from the optical core via dynamic MPLS signal requests MPLS Signaling • Benefits: • Sub-second restoration in case of failure • Automatic addition of resources in response to demand • Layer 1 & Layer 2 are active participants in service delivery

  13. Unified Network ManagementFor IP Services • Single service console for IP Services • Creation and management of all IP Service elements: Customer Located Equipment (CLE), Service Switch, Core • Service creation built within virtual routers • Policy driven network behavior not “port-by-port” configuration using network directories– like the voice network. • Flow-through integration with Layer 2 infrastructure • Automatic connections between devices • End-to-end within layer-two framework • Layer-one integration with dynamic signaling: • On demand bandwidth creation driven by Service Intelligence through ODSI/OIF Optical Interface Benefit: scalable, single seat management with end-to end provisioning, monitoring, fault isolation

  14. Intelligent IP Service Management • Provisioning • Unified – supports all network elements actively enforcing Service Attributes • Scaleable – Virtually centralized with distributed content • Integrated - Built on top of a single platform • Flexible – GUI or API driven • Surveillance/Assurance • Common Fault and Performance architecture • SLA Assurance w/detailed analysis • Capacity planning • Historical trend analysis

  15. Radically Different Approach • Policy driven network behavior • Not “port-by-port” configuration • Configure the network services, not the devices • Let the devices grab configuration elements and change behavior as users of a service arrive at a port • IP Framework for Services • Service creation built within virtual routers • On edge of service provider network • Driven by central database servers

  16. Voice: Policy Makes The Difference TCAP • Traditional voice services • SS7/TCAP and central services • Service elements: circuit-based connection oriented services • Reliability, predictability, security, billable connections User provisioning is to a directory Back-office Customer care 5ESS Service Endpoint User 5ESS 5ESS 5ESS

  17. Data: Policy Makes The Difference Web/ Corba LDAP (Oracle) Back Office Customer Care • IP Data Services • RADIUS/LDAP user-level policy • Service elements: predictable bandwidth, security, connection oriented IP • IP “conference calls” • Managed bandwidth services per application • Predictable “SLA’s” for customer and carrier User provisioning is to a directory SIN Data Service Endpoint SIN Data User SIN SIN

  18. Policy Driven Service Creation • As with voice: • Specific subscriber profiles drive network element behavior • Same with Data: • Network elements interact with provisioning servers • Service Provider defines services • Active network “reacts” to policies • Sets-up network resources on behalf of users • Uses MPLS, other technologies to signal for enforcement of service attributes

  19. Web-based Service Selection Web server, presents HTML page collects service request, updates DB User HTTP Request Service Selection Page User connects to VR Service Provider HTML VR Web Server IP Network ATM HTML User browser set to service provider homepage for service selection LightShip Call Logging Receiver LightShip Configuration Server LDAP records Database • Enables powerful flow-through provisioning • Users can “turn up” or change certain services themselves • Users edit web pages that update LDAP service profiles • Active network elements get “change notice” • Network elements download new profile & provide service
