At the recent SG15 meeting, several ASON Recommendations were revised. 
WGs have interests in control plane technology for transport networks,
this update is provided to continue 
collaborative work.
Q12/15 has developed a Revision to the ASON architecture Recommendation
G.8080/Y.1304.  This 
Revision combines Amendments 1 and 2, and adds additional material on
terminology, multi-layer aspect, 
naming, and more examples of component interaction.  As a result of an
earlier liaison received from IETF, 
the routing component interface now accommodates the PCE architecture. 
Please note that the 
requirements of the G.807/Y.1302, “Automatic Switched Transport
Network requirements�, have been 
incorporated into G.8080/Y.1304 and that G.807/Y.1302 is superseded.
Q14/15 has developed a Revision to Recommendation G.7713/Y.1704,
“Distributed Call and 
Connection Management� (signalling).  This revision combines
Amendment 1 and adds material on 
restoration, Soft Permanent Connection service, and signalling
controller resilience.  Requirements for 
crankback were not included and we continue to work on them.
Q14/15 has also developed an Appendix on “Usage of the Different
Discovery Mechanisms� to 
Recommendation G7714.1, “Protocol for automatic discovery in SDH and
OTN networks�.  This 
appendix provides clarification of the network scenarios under which
the various discovery mechanisms 
described in the main body of the Recommendation may be utilized. 
G.7714 and G.7714.1 pertain to 
discovery in the transport plane.
We look forward to continuing work with IETF on ASON related topics.
