1 introduction

E-Strategies (WTDC 2002 Istanbul)

Mission:Assist developing countries in harnessing the potentials of ICTs to contribute towards reducing the social divide, improving the quality life, promoting universal access and facilitating entry into the information society.In all actions, take into account the needs of rural, isolated and poorly served areas and people with special needs (Gender, Youths and Indigenous People).

World Telecommunication

Development Conference

7 to 15 March 2006 (Doha, Qatar)



  • Providing assistancein technical and policy aspects ofInternet Protocol (IP).
  • The ITU Plenipotentiary Conference (Marrakech in 2002) :
  • to discuss policy, operational and technical issues on the Internet in general and the management of Internet domain names and addresses in particular for the benefit of Member States.


Broadcast TV

Fiber, PLC


DSL, Cable, PLC




E-mail, Chat, SMS


Technology and application interaction


2.1 Interconnections are Key issues

Direct connection




Interconnecting via third party operated Internet Exchange Point



  • Economy of scale advantages through interconnection over an IX:
  • cost for maintenance and administration
  • cost for equipment
2. Challenges of Change: IP Telephony, Broadband and Interconnections, the high way for Telecom operators

Two different types of interconnections; peering and transit.


is an interconnection business relationship whereby ISPs provide

connectivity to each others´customers


From an ASP (Access Service Provider) to ISPs. The Internet business in most Countries is mainly based on transit bandwidth...

It is the business relationship whereby one ISP provides (usually sells)

access to all destinations in its routing table.


ISPs : From Transit to Peering in order to improve

and optimize the network efficiency/quality

Transit Provider / Access Service Provider

Transit = $$$, ~3 s

Transit = $$$, ~3 s



Peering = $, ~3 ms

2 2 the growth of voip
2.2 The growth of VoIP
  • At the start of 2004, there were more than 102 million broadband subscribers in about 100 countries where broadband services were available.
  • Republic of Korea was the leading economy at the start of 2004, with 23.3 broadband subscribers for every 100 inhabitants.
  • In terms of absolute number of subscribers, the United States was the largest single broadband market at the start of 2004, with over 25 million subscribers.

China added 11 million new broadband users in 2003 to reach 13.5 million, and at current rates of growth, it was expected to overtake the United States by year-end 2004 as the economy with the most broadband users.

  • (China had already overtaken the United States in terms of fixed lines in 2002 and mobile phones in 2001).
  • Vonage and Skype are some of the companies that are active in the VoB market. Vonage markets a flat-rate calling plan (unlimited calls in North America for USD 24.99) per month and international virtual numbers which allow for international calls to and from the United States at local call rates.
  • Skype in partnership with Colt, Level 3, Teleglobe or iBasis
  • SkypeOut network. PC to phone in 22 countries in Europe, Asia, in America

Voip Buster :

Initial charge 5 euros and Free : Austria, Denmark, Finland, Germany, Greece, Ireland, Luxembourg, Netherlands, Norway, Spain, Sweden, Switzerland, United States.


IP Telephony: ITU-T H.323 deployment scenarios

  • The Gateways (GW) provide many services, the most common being a translation function between H.323 conferencing endpoints and other terminal types.
  • A Gatekeeper (GK) is the most important component of an H.323-enabled network. It acts as thecentral point for all calls within its zone and provides call control services to registered endpoints.
  • Multipoint Control Unit (MCU) supports conferences between three or more endpoints

Output to VoIP via E1 digital trunk from PSTN lines

  • Conversion from standard analog subscribers to E1
  • Fixed-to-mobile conversion
  • Connecting old PBX to digital trunks

2.4 Security issues in Multimedia and VoIP

Security threats in Multimedia communications

User and terminal authentication
  • Server authentication
  • User/terminal and server authentication counter-security threats, such as masquerade, man-inthe-middle, IP address spoofing and connection hijacking.
  • Call authorization is the decision-making process
  • Signalling security protection addresses protection
  • Voice confidentiality is realized through encryption of the voice packets
  • Key management
  • Interdomain security deals with the problem that systems in heterogeneous environments have implemented different security features because

ITU-TRecommendation H.530 covers such security needs by addressing security aspects as:

  • –  Mobile terminal/user authentication and authorization in foreign visited domains.
  • –   Authentication of visited domain.
  • –   Secure key management.
  • –   Protection of signalling data between a mobile terminal and visited domain.
  • In addition to H.235, H.350 and H.350.2 provide for scalable key management

Business Strategies : “Triple Play”




(EoIP for Everything on IP)


Italian Case Study: “FastWeb”

  • 2000, proposed “Triple Play” Solution (VoIP,Internet and Video)
  • Main cities: Milano, Roma, Gênes , Torino, Naples,
  • Bologna, Rimini, Modène).
  • ADSL (Down Stream 4 Mb/s and 512 kbits/s upStream) for « triple play ».
  • FastWeb belongs to e.Biscom(italian Compagny)
  • Investement 1,9 billion Euros (2000-2003)
  • PPP Investors (Milan city, Power compagnies AEM- Azienda Energia Milano).
  • Infrastructure belongs to Metroweb (a joint-venture e.Biscom/AEM).
  • FastWeb is responsible for Business Management

330’000 subscribers (2003)

  • 131’500 Subscribers in (2002).
  • 1’000 subscribers every day (70 % for Triple Play with no limitation for national Communication, Video communication(10 Mbit/s, no time and volume limitation)
  • Price 110 euros/m (USD 145) + 95 euros for the installation.
  • For TV Option: Contracts with (RAI- italian TV, Mediaset and La7). Access to BBC World, Bloomberg, RAINews 24 ou RAISat Sport and other sports. Access to VoD (Video On Demand). 4 to 6 Euros/film

VoIP calls: 3,5 millions on FastWeb’s Network

  • 20 % of the subscribers use the videocommunication (represents 34 % of the total Traffic)
  • The Revenue Average is 790 euros/year + 130 euros (VoD) / Sub.
  • Technologies Partners include : Cisco System, Pirelli, Telsey (gateways and terminals), Alcatel, Marconi and NetCentrex ( for VoIP and videocom)
  • National Strategy for the moment
  • Positive cash flow expected in 2005
3 4 key strategic issues to be analyzed
3.4 Key strategic issues to be analyzed

Legal interception

Some regulatory agencies fear that voice over broadband services may open the way to ill-intended users to hide behind anonymity to conduct illegal activities (for example, drug dealing or terrorism). If the service is non-licensed, then it may be difficult for legal authorities to trace, or monitor, suspicious calls.

Taxation Model

It may be inefficient to tax only licensed operators, because this will encourage those licensed operators to shift more of their traffic onto untaxed VoIP platforms/Triple Play.


Interconnection payments

The completion of a long-distance or international call typically requires the cooperation of two or more PTOs, at the origin and destination of the call and for transit. The PTO handling call termination and transit may require interconnection payments from the originator of the call.


Policy and Administration of IXP

  • The decision to be made is on having Bi-lateral or
  • Multi-lateral peering agreements to rule over the traffic
  • exchange over the IX:
  • Multi-lateral peering agreement implies that allconnected ISPs must peer with all other ISPs connected to the IX, on the same conditions.
  • Bi-lateral leaves it to the ISP to decide with whom to peer and on what conditions, but they must have peering agreements with at least two if they want to use the IX.


  • Joining
  • Termination
  • Payment of fees


  • Policy of IXP
  • Connection agreement
  • Service definition

Medium Voltage Cable

4 conclusion
4. Conclusion

Data traffic is growing more (10 times) compared to the voice traffic and as a consequence, the past concept of telephone networks, which also carry data might be replaced by the concept of data networks that also carry voice.

In this regard, seam-less interworking between IP-based networks and PSTN and the interoperability of their respective applications or services is essential in meeting the business requirements placed on modern communication networks.

Best practices for DNS and IP addresses Management
  • Governing Law and Dispute Resolution
  • Clear responsibilities IXP/ Member Responsibilites
