Body |
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 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“Automatic Switched Transport Network requirements�, have been incorporated into G.8080/Y.1304 and that G.807/Y.1302 is superseded.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.
