1	Introduction
ITU-T Study Group (SG13) Question 5 has been considering the
architectural aspects related to the  separation of identifiers from
locators.
A draft ITU-T Recommendation is under development, currently known as
“Y.FAid-loc-split - Functional architecture for the support of
ID/locator separation in NGN” which is attached to this liaison for
consideration and comment by relevant IETF WG.
The following IETF WGs groups, among others may be relevant: hip, lisp,
mif, shim6.
Given the number of possible approaches and solutions, the ITU-T is not
entirely sure which, or how many IETF working groups are involved, and
so this liaison is directed firstly at the Internet Area directors so
that they may select the appropriate working groups relevant to this
subject. 
2	Compatibility/Synergy with IETF activities
The ITU-T  recognises the IETF’s role in developing the protocol
solutions to be used and the ITU-T seeks to describe the appropriate
architectural aspects associated with them.
It is hoped to obtain consent to the draft Recommendation mentioned
above at the January 2011 meeting of ITU-T SG13, subject/according to
IETF comments.
It would be extremely helpful to the ITU-T Study Group 13 if the
appropriate IETF Working Groups could provide their comments as soon as
is practicable in order for them to be taken in preparing the document
for consent by SG13 Q5 at the next meeting scheduled for 17 - 28
January 2011.
