All, The primary interface to SDNC is based on the RESTCONF standard, which is implemented in OpenDaylight. When SDNC was first conceived, the RESTCONF protocol was defined based on an internet draft : see https://datatracker.ietf.org/doc/html/draft-bierman-netconf-restconf-02
Since then, that version of the RESTCONF has been superceded by RFC 8040 (https://www.rfc-editor.org/rfc/rfc8040.html), which is NOT backward compatible with the earlier Bierman-draft-02 specification. OpenDaylight – and by extension CCSDK/SDNC – has supported both versions of the RESTCONF interface for several releases. However, OpenDaylight deprecated support for the Bierman-draft-02 version in their Sulfur release – the version used in ONAP Kohn. OpenDaylight no longer supports the Bierman-draft-02 spec in their Chlorine release, which is used in ONAP London. Details on the differences between these 2 versions and with the approach we have taken to mitigate the impacts of this change can be found here : https://wiki.onap.org/display/DW/SDNC+R12+London+Architecture+Review?preview=%2F162103430%2F162103431%2FRESTCONFMigration.pdf CCSDK /SDNC will continue to support the Bierman-draft-02 version of the RESTCONF API in the ONAP London release by taking over support for the bierman-draft-02 OpenDaylight code. However, we cannot continue to support this version going forward. Consequently, we hereby announce that support for the Bierman-draft-02 interface is deprecated in the ONAP London release and will be removed in the ONAP Montreal release. We believe that most current use cases – including ORAN – have already moved to RFC 8040, and so we hope the impact of this change is isolated. If any project/use case believes that they will need extended support for the Bierman-draft-02 version beyond the London release, I would ask that they assist in providing any resources necessary to upgrade the Bierman-draft-02 code.
