Open standards: a call for change - [ITU-T kaleidoscope]

Digital communication is both pervasive and vital across society. This creates a growing public interest in the technical standards that proscribe public communications. The public is demanding open standards. The rallying cry "Open Standards" means different things to different groups. This article reviews the different needs of specific groups of society and develops ten different requirements for open standards. To implement these requirements, changes to the rules and procedures of standardization organizations, international bodies (e.g., WIPO, WTO), and national patent office rules are proposed. Interestingly, technical changes, in the form of new standardized protocols, rather than legal or policy changes, appear to be the most important changes to meet the requirements of open standards."Standards function as feathers that guide the arrow of technology. While feathers are light and seemingly trivial on an arrow's shaft, without feathers, few arrows find their mark. Without standards, few technologies find their market"     

A new generation network: beyond the internet and NGN - [ITU-T kaleidoscope]

This article describes requirements and fundamental technologies to enable the provision of a new generation network beyond the Internet and the next generation network, both of which are based on IP protocols. Although the Internet has grown into a social infrastructure and the NGN will replace legacy telephone networks and cellular phone networks in the near future, it is time to start R&D on revolutionary network technologies and clean-slate designed architecture beyond the IP structure. Here some R&D activities for a new generation network are shown. This article is a revised version of the author's presentation in the First ITU-T Kaleidoscope Academic Conference [1] held in Geneva last May.     

Differential phase shift-quantum key distribution - [ITU-T kaleidoscope]

Quantum-key distribution has been studied as an ultimate method for secure communications, and now it is emerging as a technology that can be deployed in real fiber networks. Here, we present our QKD experiments based on the differential- phase-shift QKD protocol. A DPSQKD system has a simple configuration that is easy to implement with conventional optical communication components, and it is suitable for a high-clock rate system. Moreover, although the DPS-QKD system is implemented with an attenuated laser source, it is inherently secure against strong eavesdropping attacks called photon number-splitting attacks, which pose a serious threat to conventional QKD systems with attenuated laser sources. We also describe three types of single-photon detectors that are suitable for high-speed, long-distance QKD: an up-conversion detector, a superconducting single-photon detector, and a sinusoidally gated InGaAs avalanche photodiode. We present our recordsetting QKD experiments that employed those detectors.     

The architecture and a business model for the open heterogeneous mobile network - [ITU-T kaleidoscope]

The mobile communications market has grown rapidly over the past ten years, but the market could reach saturation in the foreseeable future. More flexible mobile networks that can meet various user demands and create new market openings are required for further growth. Heterogeneous networks are more suitable than homogeneous networks for meeting a wide variety of user demands. There are two types of heterogeneous networks: a closed type, where network resources are deployed and operated by communication carriers, and an open type, where network resources can be deployed not only by existing operators, but also by companies, universities, and so on. It will be easy for newcomers to enter mobile businesses in an open heterogeneous mobile network so many innovative services are likely to be provided through cooperation between various companies or organizations. This article proposes a revised architecture for TISPAN-NGN, which corresponds to heterogeneous networks and open mobile markets, and presents a new business model.     

The first ITU-T kaleidoscope event: innovations in ngn - [Series editorial]

The Feature Topic of this issue is about the first International Telecommunication Union - Telecommunication Standardization Sector (ITU-T) Kaleidoscope event that took place in Geneva, Switzerland on 12-13 May 2008. This was an academic conference on Innovations in NGN (Next Generation Networks) that brought together over 220 participants from 48 countries, including students and professors from 43 academic institutions.

The working methods and basic rules of standardization in the standardization sector of the international telecommunication union: ITU-T

ITU-T offers a unique contribution-driven and consensus-based environment, with the latest collaboration tools and facilities. Working methods and approval processes are subject to regular review. Today standards (ITU-T recommendations) can be approved and published in a remarkably short period of time - in six languages and with tight editorial controls applied. Procedures have been fine tuned to ensure that work can be started in a new area in a timeframe which matches the fast-paced ICT environment to which ITU-T Recommendations provide a strong set of foundations. This article outlines ITU-T rules and structure for those interested in contributing to the work of the world's only international, intergovernmental standards organization.

Bridging the standardization Gap to provide QoS in current NGN architectures

The provisioning of quality of service is mandatory to ensure the success of next-generation networks in an all-IP environment. In this article we describe all the problems we faced during the design, implementation and validation of the EuQoS system (which has been demonstrated as a viable solution to provide end-to-end QoS over heterogeneous networks) and some recommendations that, according to our experience, should be taken into account to success in the specification of an NGN architecture able to improve the quality of experience (QoE) of Internet users, following net neutrality requirements. In particular, we highlight the importance of defining transparent and usable end-user interfaces and the impact of specific network equipment implementations on the deployment of NGN.     

Introduction to the ITU-T NGN focus group release 1: target environment, services, and capabilities

This article starts by introducing some interesting use cases of set-vices and capabilities to be supported in next-generation networks. The target environment, relevant services, and some critical capabilities identified by the ITU-T Focus Group on NGN for the first phase of NGN deployments - NGN Release 1 - are then described. Finally, some examples of services to capabilities mapping are provided.     

The ITU-T BICC protocol: the vital step toward an integratedvoice-data multiservice platform

At the end of 1999, the ITU-T completed the first edition of the Bearer-Independent Call Control (BICC) protocol, just nine months after the start of this activity. The development of BICC can be considered historic. For the first time a full-fledged operator-grade PSTN/ISDN service can be offered over a variety of packet networks, using only standardized protocols. This tutorial explains the BICC architecture and the operation of the BICC protocol     

The broadband call control demonstrator — a platform for ITU-T, DAVIC and TINA-C implementations

The paper firstly provides an introduction to the broadband call control demonstrator platform developed at BT Laboratories. It describes the basic connection level functionality used to give point-to-point and point-to-multipoint call demonstrations. It then describes the introduction of a Digital Audio-Visual Council (DAVIC)-conformant session control capability and how this is used as the basis of a more comprehensive demonstration. The paper also examines how future networking concepts such as object orientation and distributed processing environments are being introduced, in particular the interworking between DAVIC and Telecommunications Information Network Architecture Consortium (TINA-C) approaches. Finally, some of the evolutionary aspects of the broadband call control demonstrator platform are introduced.
