Report by @Payam Forghani

• an ongoing process to define the term, use cases for M-plane

• what to measure?...

• end-to-end latency measurement

working on metric logs ongoing

• looking for time-stamps and analyze them

• some code artifacts will be upstreamed to ONAP SDN-R

RunTimeConfigDB

@Joanne Liu Rudel @Shankaranarayanan Puzhavakath Narayanan@N.K. Shankaranarayanan

I got the following Action Item from RunTime Config DB Meeting notes Feb 21, 2019
Further infos: Configuration Persistence Service Project

Convert yang model in SDN-R to be used into CCSDK. RTCfgDB will be used for OOF/SON/PCI first. Yang model as used by OOF/SON/PCI to convert. Yang model from SDN-R > CCSDK. SDN-C gets yang model from SDC. Yang to SQL. Need to have 1 Yang model.

In order to convert yang files, we need to know more about the target format of the conversion. We would prefer a document explaining the mapping details from YANG to SQL and from SQL to YANG. An easy way of the conversion is to translate YANG to its xml representation YIN and then group them in a single xml file with a xml-warpper tag. An example attached.

One yang as requested does not scale, due to the dynamics when new devices are connected to SDN-R exposing new yang models.
