2019-10-09 Meeting notes (SDN-R)

Problem statement:

Subtree filter is not very efficient when just keys for tables or a few attributes for objects should be inquired. 

NetConf RFCs also propose xPath filters:

• RFC6241 section 8.9 (https://tools.ietf.org/html/rfc6241#section-8.9) and
• RFC7950 secsion 6.4 (https://tools.ietf.org/html/rfc7950#section-6.4)

Proposal:

Add xPath filtering to odl-netconf.

To be discussed:

Impact on mdsal  - if any?

The current state of ODL RFC8040 implementation (RFC8040) - RestConf at the northbound side supports xPath.

Next steps.

ODL Plastic (as the translator)

• Need for µTranslationFramework on each side – API provider and API consumer.
• Every provider/consumer has µTranslationFramework from the very beginning – by default, the mapping/translation is just 1:1 or better f(x) = x.
• The µTranslationFramework should have the capability based on “hand-shakes” to download a new translation function on demand.
