Starting Quote

• Solid state LED technology will make the light
  bulb a thing of the past. Voice Over Internet
  Protocol will spell a revolution in Telephony.
  Even more powerful microchips and ever faster
  chip-to-chip interfaces will allow for new
  applications in anything from systems management
  to cinema -quality computer games.

• The future of lighting --OLED--
• The future of telephony --VOIP--
• The future of networks --NGN--

Technology Development Trends

• Increased speed and density of Integrated
  Circuits (Moores Law).
• Enhanced Transmission capacities on Optic Fibre
  Networks and Networking Flexibility (Gilders
  Law).
• Distributed and Open Platform-based Communication
  Software (APIs, Virtualisation, Cloud Computing).
• Capacity Growth and new Application Services on
  Wireless (Coopers Law).
• Emergence of Next-Generation Networks (IP-based)-
  Delivery of QOS for realtime applications.
• Ubiquity of networks through RFID IPv6 (Next
  Generation Internet).

5
Evolution of VOIP (Voice Over Internet Protocol)

• IP-based Networks have established themselves in
  the voice and video domain.
• Packet Networks gone beyond Best-Effort tag
  and countering the limitation of security and
  reliability.
• Cost advantage and transmission efficiency of
  VOIP leading to Death of Distance.
• Media Gateway, Soft-Switch, IMS enabling
  co-existence of circuit-switched networks and
  packet-switched networks in a seamless manner.

6
Next Generation Internet (IPv6)

• IPv6 is the next generation Internet protocol
  with improvement over the age old initial
  version IPv4 (since 1981).
• It has capacity to expand the available address
  space on the Internet enormously, using 128 bits
  vis-à-vis 32 bits of IPv4.
• Address limit of IPv4 is of the order of 4
  Billions, while that for IPv6 is 3X1039.
• (3000 Billion Billion Billion Billion).
• Mobility and Security Support

7
Trend Towards Convergence NGN Evolution

• Evolving Networks leading to Convergence of
  Voice, Data Video services on a common
  infrastructure resulting into cost saving and
  performance improvements as well as leading to
  new avenues for revenue generation for Operators
  whose ARPU has been ever depleting.
• Convergence of Telecom, Broadcast and Internet
  leading to Multimedia services.
• Evolving NGNs and 21CNs capable of guaranteed QOS
  and high level of Security, Reliability and
  Flexibility.
• Emergence of single Information Plug- (Quad-
  Play).
• Customers aspiration Better, Faster, Cheaper,
  Secure, Ubiquitous.

Definition of Next Generation Network (ITU)
Next Generation Network (NGN) is a packet-based
network able to provide services including
Telecommunication Services and Able to
make use of multiple Broadband, QoS-enabled
transport technologies in which service-related
functions are independent from underlying
transport-related technologies It offers
unrestricted access by users to different service
providers. It supports generalized
mobility which will allow consistent and
ubiquitous provision of services to users.

What is NGN Ecosystem?(From Laymans point of
view)

• Next Generation Services Converged
  (quad-play-voice, data, video, mobile)
• Next Generation Access High speed (Broadband)
  IP based connectivity (ADSL, VDSL, Wi-Max, Cable
  TV, FTTH, PLC)
• Next Generation Transport Carrier Ethernet,
  IP-MPLS
• Next Generation Architecture Service oriented
  (SOA), layered (transport, control, application)
• Next Generation Mobile 3G (B3G)
• Next Generation Internet IPv6
• Next Generation Interconnect Capacity and
  Quality based
• Next Generation Licensing Unified
• Next Generation Regulation Converged, light
  handed

intelligence at every layer

Advantages of NGN

• NGN makes use of best of both the worlds
  (Flexibility, Efficiency Innovativeness of IP
  and QOS, Security, Reliability, Customer-friendly
  features of proven PSTN.
• Advantages for service providers
• Reduced CAPEX due to integrated and efficient
  IP-based technology (Packetize or Perish)
• Reduced OPEX due to transmission cost saving,
  less power consumption, less space requirement,
  less OM costs
• Ability to offer increased range of services
• More flexibility increasing market penetration by
  offering personal service customization and
  management
• Single network layer for management
• No need for separate networks for voice, data and
  video
• Advantages for subscribers
• Reduced call charges
• New innovative services at a fast speed
• Single connection and bill for voice, data,
  video,mobile (Quad play)

14
Emerging NGN Applications EOIP
15
Fixed Mobile Convergence (FMC) A compelling NGN
application

• FMC is convergence of access for telephony
  wherein as per the convenience of the users an
  mobile call can be delivered on fixed phone or
  can be terminated through Fixed/ Wifi broadband
  network on mobile phone.
• Main motivation for this is -
• 1. Spectrum shortage leading to congestion and
  reduced QoS. (It is believed that 70 of the time
  a mobile call recipient is on a fixed
  location/Hot Spot)
• 2. Mobile subscribers saturation, Fixed lines
  decline (Battle for in-building minutes)
• 3. Broadband becoming ubiquitous and cost
  effective
• The Mobile Handset is becoming a multi-purpose,
  multi-band, multi-mode palm-held computer
• NGN Technologies enabling FMC (IMS, UMA)

NGN Regulatory Security Challenges

• i) Death of distance and blurring of the
  traditional boundaries between Access (local)
  service and Long Distance carriage.
• ii) VOIP as a disruptive technology putting a
  challenge for the regulators to perform a
  balancing act in maintaining level playing field.
• iii) Need for new interconnect products based on
  capacity and quality (VV) in place of those
  based on distance and duration (miles minutes).
• iv) Access to emergency services like police
  control room, fire services, medical help etc.
  (PSAP, E 911 (US), 999 (UK), 100 (India))
• v) Security monitoring like legal interception
  monitoring (LIM), Wiretap, CLI etc.
• vi) Data protection and privacy issues

24
Protection in Cyberspace

• Self-discipline by users- Access
  control,Authentication,HTTPs,careful about
  Identity theft, remember my password, sharing
  personal/ bank/credit card details, spam mails,
  Two- factor Authentication, Protecting your Wi-fi
  access point.
• Self-regulation by service providers- Filters,
  Blocking, Educating the customers
• Government control
• I. IT (Amendment) Act, 2008 Data privacy, data
  protection, cyber security, Netizen protection.
• II. CERT-IN blocking of anti-social and
  anti-national sites, cyber security ecosystem,
  training and education
• iv) Way forward
• Empowered autonomous regulatory body for cyber
  Content regulation and Awareness building and
  Education
