VES-HV collector has been proposed, based on a need to process high-volumes of data generated by a large number of NFs. The driving use-case is the 5G RAN, where it is expected that up to 10k NF instances report the data. It is expected as well, that the frequency of data transmission will be pretty high (per PNF instance). The network traffic generated in simulations has shown, that GPB serialization is 2-3 times more effective, than JSON serialization existing with VES collector.
