13 The task of the Data File Collector is to collect files from traffical nodes in the RAN.
16 * The DFC received a File Ready VES event from a Kafka topic. This contains a list of all available files.
18 * The DFC fetches files that are not already fectched from the traffical node. This is done using one of the supported file transfer protocols.
20 * Each file is stored in an S3 Object Store bucket or in the file system (in a persistent volume).
22 * For each stored file, a file publish message is sent to a Kafka topic for further processing.
