5G - Real Time PM and High Volume Stream Data Collection

Real Time Performance Management Data Delivery to ONAP

•Event driven high volume data delivery from xNF to ONAP/DCAE. A new VES-HV Collector will support GPB over TLS/TCP(committed). xNF will generate hvMeas events containing real time PM data. These events will be GPB encoded and transmitted over TLS/TCP. A new collector is needed as the existing collector supports REST/JSON only.
•The collected events will be published to DMaaP and sent directly to the Kafka Cluster (not planning to use the DMaaP-MR).

DCAE	Lusheng Ji	DCAEGEN2-565: HV VES Collector Service Closed	Enhance DCAE performance measurement (PM) data collection to support near real-time (order of seconds) data. Introduce a high-volume VES collector using a persistent connection (TCP socket), support a new data encoding (GPB).
		https://lf-onap.atlassian.net/browse/DCAEGEN2-564	Support VES Version 7.0 specification and new hvMeas domain (Dependency for us to finalize) NOTE SINCE GPB ENCODING IS USED PLEASE SEE THIS LINK FOR DOCUMENTATION https://onap.readthedocs.io/en/casablanca/submodules/dcaegen2.git/docs/sections/apis/ves-hv/index.html

Test Cases

Flow Step	Test Case Description	Status

Flow Step	Test Case Description	Status
Authenticate Connection	Verifying the connection can be established using TCP	Passed
NF sends Real Time PM event and HV-VES Collector validates Event	Verify that VES Collector can receive and validate the hvMeas event—a) success—event header and field population agrees with GPB and b) failure event does not agree with GPB specification	Passed
Publish Event	Verify that direct publication is done successfully to Kafka)	Passed
Topic Content Validation	Using a simple analytics program subscribe to the RTPM topic and using PM Dictionary/e.g. PM Content Meta Data and proto file generated code decode the data and display	PAssed
Additional Test Case for Performance	Send Events rapidly to HV-VES Collector to assess any bottlenecks/areas needing scaling (HV-VES, Kafka etc)	Passed
