    Next Generation Network Next Generation Network Presentation Transcript

    • Next Generation Network
    • Definition
      • A Next Generation Network (NGN) is a packet-based network able to provide Telecommunication Services to users and able to make use of multiple broadband, QoS-enabled transport technologies and in which service-related functions are independent of the underlying transport-related technologies.
    • Three Principle Benefits of Next Generation Network
      • Greater flexibility, in terms of the technology and services offered
      • Access to a wide range of new applications specific to next generation networks
      • Significant reduction the cost of running and maintaining separate date, voice, and Internet services.
    • Softswitch
      • The most crucial element of the Next Generation Network
      • Supports Open Application Programming Interfaces (APIs)
      • Due to the open APIs, it allows service providers and third-party developers to innovate new applications
    • Softswitch
      • Softswitch = Open APIs
      • Open APIs = Programmable Network
      • Programmable Network = Easier Bandwidth Changes
    • Quality of Service (QoS) Protocols
      • Resource Reservation Protocol (RSVP)
        • allocates network resources according to an application’s Quality of Service request, but it is subject to bandwidth management policy
      • DiffServ
        • network traffic is classified and network resources are allocated according to bandwidth management policy
      • Multi Protocol Label Switching (MPLS)
        • allocates bandwidth management through using a network routing control according to encapsulating packet headers
    • Companies Delivering NGN
      • BSNL and Tata Communications
        • Indian companies that have led the way in implementing NGN voice trunking networks moderately earlier as compared to their telecom counterparts
      • Cisco and Itatel
        • providing an evolutionary path for traditional voice network providers to upgrade their network
    • Regulatory Issues NGN
      • Interconnection
        • refers to the new types of products that will be used to connect packet switching services
      • Licensing
        • the licensing organization needs to stay neutral to maintain a competitive environment between different infrastructures offering Next Generation Services
      • Universal service
        • recreate universal service obligations from offering a particular service to offering network access with a specified minimum capacity and quality
    • Regulatory Issues NGN
      • Sector specific regulation
        • important for policy makers to establish an all-inclusive convergence regulation to be successful
      • Infrastructure vs. service competition
        • separation and market barriers being low equals increased market entry for new service providers if allowed by regulators
      • Quality of Service (QoS)
        • customers comprehend the QoS associated with the diverse service offerings and consumer interests are protected
    • Global Implications NGN
      • Many countries throughout the world have made network developments on NGN a priority including:
        • Africa
        • Chile
        • China
        • France
        • Japan
        • Russia
        • Saudi Arabia
        • Sudan
