High Volume VNF Event Streaming (HV-VES) Collector
HV-VES collector has been proposed, based on a need to process high-volumes of data generated frequently by a large number of NFs. The driving use-case is described and published within presentation during Casablanca Release Developer Forum: Google Protocol Buffers versus JSON - 5G RAN use-case - comparison.
The goal of the collector is to support high volume data. It uses plain TCP connections. Connections are stream-based (as opposed to request-based) and long running. Payload is binary-encoded (currently using Google Protocol Buffers). HV-VES uses direct connection to Kafka. All these decisions were made in order to support high-volume data with minimal latency.
