Network Based IP Services Horace Lau Senior Market Development Manager Lucent Technologies, INS IP Services Business Unit 5/25/2017 Lucent Technologies – Proprietary 1 Public IP Services; Not The Internet • The road to profits is in Public IP Services Networks – 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 5/25/2017 Lucent Confidential 2 Value-added IP Services Deliver Competitive Advantage Margin % Commodity Services Access Services 5/25/2017 Bandwidth-Managed Services IP VPNs Managed Security Business Internet Access Converged Services Content Management/ Acceleration Wholesale Subscriber Management Value-added Services Lucent Confidential Commodity Services Core Backbone Services 3 Service Providers Need Business Quality IP Services Network Wireless PSTN Data Services Public IP Network Optical Core • Services • Connectivity • Performance • Reliability • Security • Simplicity • Affordability • Flexibility • Scalability • Ubiquity Best Effort Internet Broadband Access 5/25/2017 Investment in public data network infrastructure will grow from $12B in 1999 to $22B in 2003. (IDC) Lucent Confidential 4 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 5/25/2017 Lucent Confidential 5 Deterministic Service Behavior • 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 – 5/25/2017 Supports MPLS paths in: • Frame based networks (core router-based networks) • ATM multi-service networks – Provides: bandwidth guarantees, latency commitments – Provides: QoS Lucent

Routing – Intelligent Agents – Service Creation Model • MPLS to create dynamic connections in and between layers in the network • Unified network management for provisioning, monitoring, fault recovery • Professional services for full public network design and lifecycle management expertise 5/25/2017 Lucent Confidential 8 Complete Service Intelligent Architecture Scalable on-ramp for IP

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 Intelligent, dynamic, scalable. 5/25/2017 Lucent Confidential 9 • 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 5/25/2017 Lucent Confidential 10 MPLS for Dynamic Connections: within the IP & ATM Transport Layers • Multiservice ATM Core delivers infrastructure for Frame Relay, DSL, ATM Access and Multiservice MPLS ATM Multiservice/ MPLS • IP Core provides infrastructure for “pure IP” networks and Packet MPLS BSTDX GX550 PSAX Family NX NX • MPLS between architectures provides for end-to-end IP services NX IP Switching/ Packet MPLS 5/25/2017 Lucent Confidential 11 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 IP/ATM Core 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 5/25/2017 Lucent Confidential Optical Core 12 Unified Network Management For 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 5/25/2017 Lucent Confidential 13 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 – 5/25/2017 Historical trend analysis Lucent Confidential 14 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 5/25/2017 Lucent Confidential 15 Voice: Policy Makes The Difference TCAP Back-office Customer care User provisioning is to a directory 5ESS 5ESS User 5ESS Service Endpoint 5ESS • Traditional voice services – SS7/TCAP and central services • Service elements: circuit-based connection oriented services • Reliability, predictability, security, billable connections 5/25/2017 Lucent Confidential 16 Data: Policy Makes The Difference Web/ Corba LDAP (Oracle) Back Office Customer Care User provisioning is to a directory SIN SIN SIN Data User Data Service Endpoint SIN • 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 5/25/2017 Lucent Confidential 17 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 5/25/2017 Lucent

ATM User browser set to service provider homepage for service selection IP Network Web Server HTML LightShip Call Logging Receiver Database LDAP records LightShip Configuration Server • 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” –
