NRF
Network Repository Function provides service discovery functionality in the 5G core network. Each network function registers with NRF with a set of properties called as NF Profile. Implements 3gpp specification 29.510. NRF Keeps the profile data for each network function in the MongoDB. Supports Discovery & registration procedure. When the discovery API is called, NRF fetches a matching profile from the database and returns it to the caller.
