A new process that allows work to be started in new areas on ‘any day of the year’, has been endorsed at the latest meeting of TSAG.

In the fast moving world of information and communications technologies (ICT) the quicker standardization work can start, the better. The ‘quick start’ process allows ITU-T to initiate new activities with speed when members identify a new area for standardization. It is a further example of how responsive ITU-T is to market needs and it strengthens ITU-T's claim to be one of the most attractive and efficient places to produce global standards.

Simply put, the process gives responsibility for taking quick action, such as setting-up a new Focus Group, a joint rapporteur group, or a joint coordination activity, to the Telecommunication Standardization Bureau (TSB) Director in agreement with the Study Group chairmen and the TSAG Chairman. Previously it was normally necessary to wait for the next Study Group meeting, which could have been months away. So, for example, if direction on a particular topic is seen to have reached sufficient maturity in Technology Watch discussions, measures can be put in place to ensure immediate action. Experts agreed that such a speedy response to market needs is essential to continue bringing the most important new work into ITU-T.

Three new Recommendations related to IP Performance have been consented by ITU-T's Study Group 12.

G.1030 - provides a framework of tools to estimate end-to-end IP network performance for some user applications. User perception of application performance in packet networks is dependent on many factors, including network end-to-end performance, performance of terminals and other devices beyond the purview of the network operator. The application’s dependency on the communications network, and the user’s task and the extent of user interaction with the application need also to be taken into account.

All these factors are used to estimate end-to-end performance levels. At this stage, the framework includes a perceptual model for web browsing. Future versions will focus on multimedia conferencing and other applications. The Recommendation is designed to be helpful for people designing networks, enabling them to know what applications can be realistically supported. 

G.1040 - defines a new performance metric in IP networks for short transactions, such as trading of stocks, automated banking, and credit card point of sale transactions. The nature of such exchanges is that they need to be quick and reliable.

This Recommendation gives the ability for the network provider to either flag a problem based on their network measurements interpreted with this metric, or to say that – if a problem exists – it isn’t attributable to the network. The Recommendation allows the network service provider to see how much of the transaction time can be attributed to the network. The metric can also be useful in drawing up service level agreements.

G.1050 - addresses Network Model for Evaluating Multimedia Transmission Performance Over Internet Protocol. The need for such a model is driven by new challenges for multimedia applications in IP. Impairments that in typical data transfers are of little consequence may be much more serious in video or VoIP for example. The model is based on statistical models of a broad range of known deployed network configurations. This way a manufacturer of networking testing solutions can avoid speculation in configuring test scenarios.

Until 1998, the ITU Global directory contained information both about ROAs that were Sector Members and non-Sector Members, but it now only contains information relating to ROAs that are Sector Members.

The consequence of there not being a published list of all ROAs (including those that are non-Sector Members) might limit the assistance such information can have on, for example, the bilateral exchange of information related to numbering changes or on introducing new international numbering resources.

The status of ROA is used within certain ITU-T Recommendations, e.g. E.118, E.164.1, E.169.1, E.169.2, E.212, Q.708, X.121 as a criterion regarding assignment of international numbering resources. Such a list would assist in the administration of international numbering resources and would facilitate the exchange of information between ROAs, for example, on numbering changes.

A consolidated list of Recognized Operating Agencies (ROAs) has been set up, derived from the responses received to TSB Circular 24 of 8 April 2005 and an individual communication was published in the ITU Operational Bulletin under the heading "Changes in Administrations/ROAs and other entities or Organizations".
