TSB
Question 4/2
To provide new or revised Recommendations which enable service quality
parameters to be identified and measured, and which establish numerical
objective values to ensure that networks provide service qualityto meet
customer/user expectations.
•Operational Considerations for QoSof Voice and Facsimile over IP-based
Networks
•Framework for service quality agreement
•Observation on international outgoing telephone calls for QoS.

At the 3-11 May 2006 meeting of Study Group 2, there were a
number of contributions concerning IPv6 distribution and allocation
Some issues identified by developing countries but not agreed by
SG2:
Avoid future geographical imbalance that might be induced by
“first come, first served”
Reduce routing table size, for example by geographical allocation
Give easier access to small ISPs and new entrants, for example by
national allocation
Comments are invited.
