Hi @Pesaraujo
NTA, which is a module from HPE IMC platform ( www.hpe.com/networking/imc ) is capable of receiving and reporting on application level visibility. Network infrastructure devices ( switches, routers, wireless, loadbalancers, etc...) which support sFlow v3/v5, netflow v5/v9, IPFiX, Netstream from HPE Routers, are capable of sending the flow export records to NTA which is able to then analyse and report on this data.
This is very similar data to what would come out of the AppRF, with the exception that the flow technologies mentioned above do not TYPICALLY go above L4 of the OSI stack ( tcp/udp port numbers ).
These technolgies are not specific to any topology/technology (MPLS, VPN, etc...) but are more generic traffic monitoring technologies.
As Tim mentioned, Airwave is still the prefered device to decode the AppRF data.
