Next Generation Network

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