Introduction
• ICT sector is developing rapidly
• Many sectors became dependent on ICT

Financial
Real Estate
Education
Health
• Currently, ICT sector is converging into a single network
based on Internet protocol (IP).Such network is known
as NGN.
• Moving towards NGN, opened many research areas
such as IPV6 and ENUM which will be required to make
the NGN more efficient.
Introduction
• Migrating from circuit switched network to
packet switched network will enable the
ICT sector to be more innovative.
• Currently, many countries started to invest
heavily in the ICT sector knowing that it
will drive the other entities into massive
success.
ENUM

•
What is ENUM
Types of ENUM
Features & Benefits
Status & Next steps
What is ENUM?
• Provides a bridge between Internet based
communications services and conventional telephone
networks
• Converts telephone numbers to domain names and
stores them
• Enables end users to associate one or more
communications addresses with their telephone number:
–
–
–
–
Internet addresses for VoIP services
Email & instant messaging addresses
Other telephone numbers
Web pages
Types of ENUM
• Public User ENUM
– The end user can provision his or her records in the ENUM
registry in the public domain e164.arpa. In other words, the end
user is the registrant for the ENUM domain name within the
domain e164.arpa
• Private Infrastructure ENUM
– Creating a domain name from a telephone number (TN) and
resolving it to a URI. It does not, however, use the domain
e164.arpa
– Private ENUM is used when there is a closed user group that
wants to use ENUM to exchange IP traffic.
• Public Infrastructure ENUM
– National number administrators typically assign TNs to
communications carriers, not to end users; carriers then assign
the TNs to end users. The carrier’s network and its associated
addresses are highly secure, and access is strictly maintained
and limited to other service providers
Features and Benefits:
•
ENUM using DNS resource records can map to different services such
as:
• E-mail Addresses
• VoIP SIP/ H.323 Servers
• Voice Mail Servers
• Fax
• Website
• Others still to be introduced…
•
ENUM enabled DNS creates a low cost shared service since DNS is
already globally available, fast, reliable, and open to public.
•
With ENUM using E.164 Telephone numbers:
• Consumers are already familiar with E.164 numbers
• One Number addressing eliminates need to remember multiple,
complex addresses
• Telephone numbers are internationally understood and linguistically
neutral
Status & Next Steps
• TRA is managing the UAE resources including ENUM
• Ready for ENUM
• Future plans include ENUM trials
IPV6
• Why IPV6 needed?
• What will it add?
• Status & Next steps
Why IPv6?
• IPv6 solves the main problem is IPv4, that is, the
exhaustion of addresses to connect to computers or
hosts in a packet switched network.
• The key features of IPv6 are:
– Large address space:128 bits as compared to 32
bits in IPv4
– Quality of Service: IPv6 brings QoS that several new
applications require such as IP Telephony, Interactive
games etc
Why IPv6?
• Mobility: Keeps the same IP address regardless of the
network and the equipment is connected to.
• Stateless Auto-reconfiguration of Hosts:
This feature allows IPv6 host to configure automatically
when connected to a routed IPv6 network.
Network-layer security: IPv6 implements network-layer
encryption and authentication via IPsec.
What will it add? – Internet for Everything
• IPV6 services or application are considered the
drivers to move to IPV6 for many, such as:
•Home Networking
•Triple Play
•Peer-to-Peer Applications
•IPv6 VPNs
•Mobile networking
•Social applications
(chat, VoIP, messaging, p2p)Digital
•IP-TVS
•IP-based VoIP
•Online gaming
•E-Health (Home Hospital care)
•Utility sector application
•Environmental Monitoring
•Sensor Networks
•Public Safety and emergency
networks
Current Status of IPv6 Deployment In
UAE
IPv6 general Awareness:
Yes
IPv6 deployment in the Public sector:
No
IPv6 deployment in the Private sector:
Yes
IPv6 curriculum in the Education:
Yes
ISP’s deploying IPv6:
Yes
Next Generation Networks (NGN)
• NGN as defined by ITU:
“A packet based network able to provide
telecommunication services and able to
make use of multiple broadband, QoS
enabled transport technologies and in
which service related functions are
independent from underlying transportrelated technologies”

Access
Convergence
• The telecom network of fixed and mobile is
converging to a single horizontal network
that provides multimedia services over an
IP based architecture.
• There will not be a circuit switched
network in the future. The voice and data
will be transported over IP.
• Universal Access:Wireline and wireless
access.
Challenges
• The deployment of NGN using Internet
Protocol (IP) connectivity to support fixed
and mobile voice, video, data and IPTV
provides new opportunities to innovative
services. It also raises new challenges
concerning Quality of Service (QoS) and
Consumer Protection.
Quality of Service (QoS)
• Excellent voice quality of the circuit switched
network. Is it going to be the same with IP based
network?
• Many issues of QoS are related to IP networks
such as voice quality, delay, jitter, etc.
• Migration from the existing network to NGN will
introduce some challenges such as service
disruption, speed of delivering the service and
quality of multimedia services.
Consumer Protection
• The introduction of IP networks will bring
challenges on how to handle phishing,
unauthorized access to personal data and
malicious virus dissemination via SPAM.
• In general, same threats available in
Internet, could rise in NGN networks.
