1. Leading the Way to An Intelligent Network Leading the Way to An Intelligent Network Technical seminar on Under the guidance of Mr. Ganesh R.M

2. Introduction Intelligent Network (IN) is an architectural concept for the operation and provision of new services which is characterized by Extensive use of information processing techniques Efficient use of network resources Modularization and reusability of network functions 3. Introduction Integrated service creations and implementation by means of the modularized reusable network functions Flexible allocation of network functions to physical entities Portability of network functions among physical entities 4. Concerns in the Network Reliability Interoperability Security Speed/Bandwidth Quality of Service Device Management Scalability 5. Intelligent Services Throughout the Network IP Routing Internet VPN PSTN Network Network Access Control QoS Delivering Services From the Edge through the Core to the WAN 6. Intelligent Network Attributes & Services IP Routing Quality of Service Network Access Control Network Management Security Quality of ServiceAvailability Delivering Services From the Edge to the Core to the WAN 7. Basic service is enhanced through added network intelligence Provides for very rapid service turnover Intelligent network concept 8. Intelligent network benefits Rapid service introduction Reduces latency of introducing new services throughout a network Robust service customization Services are adaptable and depend on the customer needs Established vendor independence Same equipment, different services, OR different equipment, same services Portable open interfaces Market is not dominated by one or two vendors, since service providers can run their products using open interfaces 9. IP Routing 10. What is IP Routing? Intelligent Decision and Action That Enables Information To Be Efficiently Directed From Intelligent Decision and Action That Enables Information To Be Efficiently Directed From One Network To Another. 11. Why IP Routing? Failures In The Network Result In Decreased Productivity Increased Broadcast Traffic As Network Grows Increased Availability Through Redundancy And Faster Failover Increased Scalability Through Better Traffic Management IP Routing Concern 12. Internet VPN Rapid Failover If One Link Fails The Other Takes Over Immediately IP Routing FAILOVER IP Routing Maximizes The Utilization Of The Network 13. The key question is: How Intelligence is provided and distributed in the network IN Conceptual Model (INCM) gives a framework which will be presented here Other models may emerge, most probably from voice, multimedia and mobile value added services in Intranet and Extranet IN Architecture 14. Principles of the IN Architecture Services and a service creation environment have become centralized in what are known as remote Service Control Points (SCPs). This basic conceptual model is defined as the Intelligent Network or IN. operation of the system is the Service Switching Point 15. IN Conceptual Model Planes service plane global functional plane distributed functional plane physical plane - protocols and processing global service logic GSL1 GSL2 GSLn POI POR SIB1 SIB2 SIBn BCP service1 service2 SF1 SF2 SFn PE1 PEn PE2 P1 P2 Pn FE1 FE2 FE1 FE2 F E A EF EF EF EF F E A Service Plane Global functional Plane Distributed functional Plane physical Plane 16. The IN conceptual model is a four-layer abstract model, where each layer (or plane) represents the capabilities of an IN network. The four planes of the model are: The service plane offers a users perspective to a services functionality and capability. Global Functional Plane incorporates service independent building blocks (SIBs) 17. The Distributed Functional Plane contains functional entities, which are a specific group of functions required to implement the IN concept Finally the Physical plane is the entity where the functional entities are implemented. 18. ASSOCIATED TECHNOLOGIES Intelligent Network (IN) is adopted in the mobile network to provide the users with diversified supplementary services, enhance the mobility management (MM) and shorten the time-to-market of new services Mobile networks have adopted IN technology To provide the users with new services that can only be obtained in the fixed network before and enhance the mobility management. 19. Convergence of technology IONs: Merging Intelligent and Optical Networks Ring architectures being applied to the optical network domain Built-in network intelligence has two aspects: node-based and network-based 20. Node-based Used to refer to the network elements intelligent software capable of sensing a module failure or a break in a fibre connection and automatically routing traffic in the opposite direction of the ring Networks are currently capable of routing 40 optical signals in less than 50 milliseconds Network-based Used to refer to the networks capability of deploying new services without physical intervention Main driver is Gigabit Ethernet (GE) and 10GE Point and configure capabilities brought all the way to the end user increase value added, as customer is directly involved in the service definition 21. Application areas Advanced Least Cost Routing Managed Roaming Access Screening Missed Call Alert Number translation Real-Time Charging Gateway 22. Future of Intelligent network Service providers are faced with the challenge of managing fast growing networks while keeping operating costs and provisioning times The old SONET/SDH network architectures and management solutions are inappropriate for the aforementioned trend ION provides optical cross-connects (OXCs), enabling the market demand for scalable and adaptable services 23. IONs will provide for ubiquitous computing architectures, as subscribers are getting used to their services IONs also will provide for on-demand service deployment, allowing for a great reach for the Internet Telecommunications Information Networking Architecture (TINA) is a consortium of the top telecommunications players focused on delivering services using next-generation software. Other consortiums will aid in the transition to IONs Future of Intelligent network 24. Thank you
