The latest meeting of TSAG saw the formation of a new correspondence group to examine what role ITU-T should have in conformance and interoperability testing for its standards.

The stamp of approval that shows conformance to a standard could be a potent marketing tool for manufacturers of equipment. 

The convener of the group Arve Meisingset of Telenor R&D in Norway, and Vice Chairman of Study Group 17 said: “There are many possibilities, from maintaining the status quo in which third parties can test for conformance without a complete set of ITU testing standards to the setting-up of actual testing labs based on ITU guidelines and standards. We will look at the pros and cons of all possibilities; examine what is appropriate for ITU to do, and what members want.”

Currently, while there are procedures in some Recommendations, there is no systematic approach to testing implementations of ITU-T Recommendations for conformance or interoperability. And, so initial steps will probably be along the lines of producing guidelines for protocol writers and users of those protocols, and examining how ITU can produce a more complete set of testing standards to help the testing community and product suppliers deliver better standards-based products.

Existing ITU-T applicable specifications include the 7-part X.290-series Recommendations that covers generic aspects of conformance testing. In addition, SG 17 is standardizing a testing methodology and framework for interoperability testing. SG 17 will write the guidelines and generic testing methodology standards while SG 11 will write protocol-specific testing standards. Other study groups have also developed specific methodologies for particular Recommendations. For example, Study Group 16 has developed a conformance testing specification for the video compression codec H.264/AVC. 

Experts agreed that future work will benefit from the more systematic method that could result from this activity.

In conformance testing, the objective is to determine how completely and correctly the requirements of the standard have been met by the implementation. In interoperability testing, the objective is to determine if two or more implementations of the same standard interoperate with each other. In the telecommunication world, it is generally assumed that the implementations have been tested for conformance prior to interoperability testing.

The third meeting of the Service and Network Operations group (SNO) will be held 20 March - 24 March 2006 at the Sandton Convention Centre, Johannesburg, South Africa at the kind invitation of Telkom SA Ltd.

SNO is a group that operates under the auspices of ITU-T aiming to address issues in network management as encountered by network operators throughout the world. It was formerly known as the Network Management Development Group (NMDG).

As "the Voice of Operations", the group has had a direct impact on existing and new ITU-T Recommendations in the field.

This SNO event aims to provide an opportunity for an open communications sharing experience among international network operators. In addition the conference aims to encourage wider global ITU-T participation in the identification, development and implementation of network and service management activities for operations.

Registration and general information can be found here.

The announcement (18 November) that ITU’s Focus Group on NGN (FGNGN) has completed work on the first set of standards for next generation networks (NGN) marks a significant step towards a fundamental reworking of the world’s information and communications technologies networks. With NGN, network operators hope to replicate the level of service and reliability that customers have come to expect in telecommunication systems across all ICT networks.

The milestone reached with the launch of the Release 1 set of specifications has been achieved in a very short time by members of ITU’s Focus Group on NGN (FGNGN). FGNGN is made up of representatives of the world’s telecoms service and network providers, manufacturers and governments.

Telecoms companies around the world are starting to make the move from the traditional circuit switched networks that have essentially been in place since the earliest days of telecommunications to an Internet Protocol (IP) based system that will create cost efficiencies and allow a much greater level of diversity for service providers. Release 1 will serve as an invaluable tool to facilitate this rollout.

Contained within the 900 pages of ‘deliverables’ are some of the high-level architecture and frameworks for NGN. ITU’s next phase of NGN work – to be called the NGN-GSI (for global standards initiative) - will focus on the detailed protocols necessary to offer the wide range of services expected in NGN. It is also expected that the GSI will aim to harmonize different approaches to NGN architecture in different parts of the world.

Houlin Zhao, Director of the Telecommunication Standardization Bureau, ITU said: “Industry is backing NGN to the tune of billions of dollars. And ITU is very proud that the world’s manufacturers of telecoms equipment, network and service providers and administrations have entrusted us with this work. They understand that global standards will stimulate innovation and superior technology and enable interoperability, protecting current and future investment. ITU is the only body in the world that will be able to offer the necessary convergence between different NGN platforms on a global basis if they emerge.”

Since extending the reliability of telecoms networks into Internet Protocol based systems is key to the success of NGN, quality of service (QoS) specifications have been a strong focus of NGN work. Additionally, security aspects, universal access and the separation of services from the underlying network have been important topics covered.

The NGN-GSI will build on the momentum generated over the past year. The period 2004-2005 has seen meetings and workshops progressing work on NGN around the world. Participation in and contributions to this work are continuing to increase.

The next phase of ITU-T NGN work will see a significant re-organization of work schedules to ensure that experts from different Study Groups are able to meet at the same time. The meeting schedule has also been designed to maintain the brisk pace established during the first phase of the NGN work, and to meet members’ demands.
