foreword
like most technology-driven industries the telecommunication sector has historically been characterized by
steady growth punctuated by an occasional leap forward usually when a new technology is introduced. this
historical pattern has repeated in the development of every new communications network technology
beginning with telegraph in the 1840s the telephone in the 1870s radio telegraphy or “wireless” in the
1890s radio broading in the 1920s television broading in the 1950s geostationary satellite
communications in the 1960s computer communications in the 1970s optical communications in the 1980s
and the internet and mobile communications in the 1990s. for the last 139 years the itu has adapted to and
embraced all new innovations in communications technologies.
in the latter part of the twentieth century the almost simultaneous arrival of two major innovations—mobile
phones and the internet—not only changed the face of communications but also gave fresh impetus for
economic growth.
this report attempts to give a snapshot view (march 2004) of how internet protocol (ip) networks and the
internet as well as their convergence with other kinds of networks have impacted on itu’s activities. in
today’s rapidly evolving telecommunications environment it is difficult to capture all of itu’s ip-related
activities in a complete and comprehensive report. however hopefully the report provides a simple overview
of the itu for the uninitiated as well as an overview of the wide scope of the itu’s activities related to ip
networks and the internet—ranging from technical standards to regulatory and policy matters to development
initiatives.
chapter one: background on itu gives an introduction to the itu its evolving role and its overall structure
and activities. chapter two: understanding telecommunication network trends explains some recent trends
in the telecommunication sector and in particular the impact of the almost simultaneous arrival of two
major innovations mobile phones and the internet. chapter three: overview of itu activities related to
internet-protocol (ip) networks describes how ip-related technologies have become strategic elements in the
design development and use of many telecommunication networks which in turn has had a major impact on
itu sector work programmes in its radiocommunication telecom standardization and development focuseddomains. this chapter also describes how decisions taken by itu member states have shaped itu’s
mandate related to ip-based networks and the internet. chapter four: internet-protocol related activities in
the itu telecommunication standardization sector describes internet-protocol related activities in the itu
telecommunication standardization sector. chapters five and six describe respectively the same for the
itu telecommunication development sector and the itu strategy and policy unit. chapter seven: case
study—how itu’s broadband standards improve access to the internet provides a practical case study of
how itu standards for broadband are improving access to the internet in particular using digital subscriber
line (dsl) and cable modem technologies. chapter eight: case study—how itu’s internet training
centre initiatives provide capacity building in developing countries is a case study demonstrating how the
itu telecommunication development sector has been assisting developing countries meet their human
resource requirements for skilled internet professionals through internet and ip-related training programmes
established at training and educational institutions throughout the developing world. chapter nine: world
summit on the information society and itu activities looks at how the wsis declaration of principles and
action plan overlaps with ongoing or planned itu activities. chapter ten: summing up makes some
concluding remarks on the report.
itu the united nations specialized agency for telecommunications is committed to playing a positive role
in the development of the information society and to extending the benefits of advances in new information
and communication technologies (icts) to all the world’s inhabitants. this is in line with the resolution of
the highest administrative organ of itu (resolution 101 of the plenipotentiary conference (minneapolis
1998)) which calls upon itu to “fully embrace the opportunities for telecommunication development that
arise from the growth of ip-based services” and subsequent ongoing calls from itu member states to
continue to actively pursue this objective.
