Liaison statement
Cooperative Relationship between ITU-T SG15 and CCAMP

ITU-T Q14/15 would like to thank the IETF CCAMP working group for the liaison
response titled “Cooperative Relationship between ITU-T SG15 and CCAMP�.
Please find below as requested our response to some of the points mentioned in
your liaison regarding our cooperative relationship between our groups based on
the example of our ASON routing protocol cooperation. Q14/15 has not responded
to the points that are addressing more general issues, i.e., procedural or
process issues since these will be addressed when the IETF management team
meets with the ITU-T SG15 management team prior to the next IETF meeting.
Q14/15 is becoming increasingly concerned about the progression of the routing
protocol work in IETF CCAMP where protocol extensions are needed in order to
meet the ASON routing protocol requirements. The ASON routing protocol
requirements were captured in the ITU-T Recommendation G.7715.1, which was
liaised to IETF CCAMP when it was consented in February 2004. Extensive
communication has occurred since then and ITU-T members have joined the CCAMP
design team to help IETF CCAMP to better understand the ASON routing
requirements. Q14/15 also provided feedback several times to IETF CCAMP through
liaisons where Q14/15 expressed its concerns that the models and extensions
being generated do not satisfactorily meet the ASON routing requirements.
Completion of the routing protocol activity is the most urgent activity where
the cooperation between our groups should be improved. Q14/15 is looking
forward to cooperate with IETF CCAMP to develop protocol solutions that are of
value to the industry. An electronic copy of this liaison statement is
