Presented by Fabio Bigi Workshop Coordinator WORKSHOP ON IP/OPTICAL (CHITOSE, JAPAN, 9-11 JULY 2002) 1

The Workshop on IP/Optical organized within the framework of ITU-T’s new initiatives, will profit from the participation of experts from the standardization sector and other SDOs, as well as eminent local experts. 2

. increase the awareness of ITU-T studies,  increase the awareness of ITU-T studies, projects, products and services,  coordinate the activities of ITU-T study groups in a particular field,  benefit from progress achieved in other SDOs, and considering the results of ITU-D and ITU-R study groups where appropriate, in order to coordinate studies and to avoid duplication of effort, The Workshops/Seminars organized by ITU-T aim to: 3

. identify new areas for standardization  identify new areas for standardization by relevant study groups in order to enhance existing and related projects, and in response to new market needs,  stimulate opinions, priorities and contributions from different regions in order to focus corresponding ITU studies, to respond to concerns of the existing membership and attract new members to contribute to the work of ITU. 4

 IP (led by Study Group 13) - This project studies the interaction of IP-based networks and telecommunications networks for multimedia and other IP applications, and considers the interoperability of IP-based services and telecommunication services to ensure the continued speed, capacity, ease of use, reliability and integrity of the public telephone networks in use around the world. This Workshop is aimed at enhancing the following special projects: 5

. OTN (led by Study Group 15) - An. Optical Transport Network is  OTN (led by Study Group 15) - An Optical Transport Network is composed of a set of Optical Network Elements connected by optical fibre links, able to provide functionality of transport, multiplexing, routing, management, supervision and survivability of optical channels carrying client signals. A set of Recommendations (ITU-T G-series) has already paved the way for future all-optical networks. 6

. Access (led by Study Group 15) - New  Access (led by Study Group 15) - New technologies, optimised for transport of packet data including packetised voice, will require the capability to support different QoS services from end to end through the network, including the access networks. Different scenarios are examined with the aim to give to the end user the seamless global multimedia services of their choice. 7

 NGN (led by Study Group 13) – The term Next Generation Network represents key technologies, realizing the concepts of the global information infrastructure. The general principles for NGN can be found in various Y-series Recommendations. NGNs are considered to be part of the “federation of networks” of the global information infrastructure. This concept enables people to securely use a set of communication services supporting an open multitude of applications and embracing all modes of information, any time, anywhere and at an acceptable cost and quality. 8

 During the official opening there will be key-note addresses given by the Director of TSB, by representatives of IETF, ISO/IEC, local universities and by the chairmen of Study Groups 13 and 15. The workshop will be organized in the following session themes: 9

1. IP over optical, business and market aspects; 2. Switched optical networks; 3. Optics in access and metropolitan networks; 4.  Optical interfaces; 5.  Optical/IP network OAM and protection and restoration; 10

7. Signalling and routing; 8. Optical fibres, cables and components; 6.   WDM and DWDM; 7.   Signalling and routing; 8.   Optical fibres, cables and components; 9.   Optical network management; 11

10. Optical switching equipment; 11. Network performance (IP/Optical); 12.      Optical network clients and services; 13.       Services and network evaluation 12

I take this opportunity to thank all contributors, the organizers and the participants for their commitment to make this a successful event. _________ 13
