At the recent SG15 meeting, several ASON Recommendations were revised.
As IETF CCAMP and PCE
WGs have interests in control plane technology for transport networks,
this update is provided to continue
Q12/15 has developed a Revision to the ASON architecture Recommendation
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, â€œAutomatic Switched Transport
Network requirementsâ€?, 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incorporated into G.8080/Y.1304 and that G.807/Y.1302 is superseded.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,
â€œDistributed Call and
Connection Managementâ€? (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 â€œUsage of the Different
Discovery Mechanismsâ€? to
Recommendation G7714.1, â€œProtocol for automatic discovery in SDH and
OTN networksâ€?. 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.
