Next Generation Network
- 2. 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.
- 3. 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.
- 4. 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
- 5. Softswitch Softswitch = Open APIs Open APIs = Programmable Network Programmable Network = Easier Bandwidth Changes
- 6. 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
- 7. 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
- 8. 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
- 9. 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
- 10. 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
