Page History

• Start recording
• Cloud storage
  • With the discontinuing ARO, need a storage for documents (deliverable, such as TR-512 etc.) and recording of conference calls
  • The current wiki has limitation on the size of the file to be posted.
    • ONF TR-512 v1.3 and recordings couldn't be post on wiki;
    • Had considered dropbox. but Chinese colleagues couldn't access dropbox.
    • Cassandra has suggested to try http://tencent-weiyun.eu5.org/.
      • Concern raised regarding copyrights issues etc.
  • Solution for TR-512 v1.3
    • Post it on ONF public library https://www.opennetworking.org/software-defined-standards/models-apis/
      • Action Item - Kam/Nigel: follow up with Timon to close the loop of v1.3 publication
    • V1.3.1 will be small and will have no issue of posting the draft on wiki. Final publication will be on the public library
    • For the future revision (e.g., v1.4), fragmenting the TR-512 suite into subsets, instead of one big-package, to avoid single big file
  • Open Issue: Still need to resolve the issue of posting the recordings.

Two ITU-T Q14/15 liaison statements from its London Interim Meeting have been received.

• These two LSs have been posted on the ARO Archive wiki page https://wiki.opennetworking.org/pages/viewpage.action?title=Liaisons&spaceKey=AA.
  • Note that access to the ARO Archive wiki page requires ONF login
  • Currently there is a problem with the access control. Access is denied even one logs into that page. Cassandra is working to resolve the problem.
  • The LS is posted here temporarily.

Summary of the LS

• Regarding coordination on IM/DM for OAM 
  • SG15-LS80: Liaison statement regarding coordination on IM/DM for OAM (reply to IEEE 802.3WG-LS54 (TD141/WP3))
  • To IEEE 802.1 & 802.3, cc ONF & MEF
  • The UML version of .1Qcx on IISOMI have been referenced for IEEE's information
    • Re-engineered ieee802-dot1ag-cfm YANG module: PapyrusOamOxygenWorkspace_171208.zip
    • Re-engineered ieee802-dot1ag-cfm YANG module diagrams: PapyrusOamOxygenWorkspace_171208-diagrams.zip
  • Issue of the current way of indexing of the Maintenance Domain (MD) Class was raised
  • Detail analysis of the CCM and LBM/LBR modeling in Q14/15 and IEEE (in SNMP) was also shared with IEEE
• On Information Modeling 
  • SG15-LS81: Liaison Statement on Information Modeling (to OIMT and OTCC Projects)  
    
    • The link for downloading the attachments to this Liaison is available from liaison archive wiki page: https://wiki.opennetworking.org/pages/viewpage.action?title=Liaisons&spaceKey=AA.
  • Informed that the issue of the data type of oduType was addressed in v3.05 of G.874.1
  • Requested multi-layer examples
    • Action Item - Kam: Schedule discussion for Dec. 14 Thursday IM-D (5:00 - 6:00 am Pacific Time)
  • Shared input on the media model
  • Share the updated editor drafts of G.874.1 v3.05, G.sync-mgmt v0.05, and G.8052.1 v0.02

G.8052.1

• Q14/15 London meeting decision

  • Aim to normalize the G.8052 on-demand and proactive measurement jobs

  • Aim to normalize the TTP & CTP classes as LTP for the OTN, Ethernet, and MPLS-TP models

  • Aim to transform the operations into attributes for the OTN, Ethernet, and MPLS-TP models

  • Concluding that LAG and Traffic conditioning/shaping are not in the scope of G.8052.1

• A sketch for the pruned/refactored MEP model was produced for G.8052.1 v0.02 

  • Sketch-PR-MEP diagram

IEEE 802.1 & 802.3

• Re-engineered ieee802-dot1ag-cfm YANG module: PapyrusOamOxygenWorkspace_171208.zip
• Re-engineered ieee802-dot1ag-cfm YANG module diagrams: PapyrusOamOxygenWorkspace_171208-diagrams.zip

Bernd presented the UML model of the IEEE cfm YANG module (re-engineered).

It was pointed out that the UML Model

• is still not complete
• contains all YANG artifacts
• mappings to be reviewed are highlighted in blue
• artifacts for which mappings are missing are highlighted in red
• attribute cardinalities are all [1] (Papyrus default) and still need to be set

The YANG modules which are imported by the cfm YANG module contain only those artefacts used in cfm; i.e., are not complete at all.

There are some open mapping issues:
Re-engineering of YANG leafrefs

Example:
leaf ma-format {
          type leafref {
            path "/dot1q:bridges/dot1q:bridge/cfm:cfm/cfm:md/cfm:ma/cfm:format";
          }

How to point to the referenced leaf format?
Possible solution: The UML navigable association end role name is equal to the referenced leaf name.

Issue: This is not always the case in cfm:

Due to time constraints it was not possible to discuss the other open issues.

• Will schedule for Dec. 14 Thursday IM-F (8:00 - 9:00 AM Pacific Time)
