* R-48917 The VNF **MUST** monitor for and alert on (both sender and receiver) errant, running longer than expected and missing file transfers, so as to minimize the impact due to file transfer errors.
* R-28168 The VNF **SHOULD** use an appropriately configured logging level that can be changed dynamically, so as to not cause performance degradation of the VNF due to excessive logging.
* R-87352 The VNF **SHOULD** utilize Cloud health checks, when available from the Network Cloud, from inside the application through APIs to check the network connectivity, dropped packets rate, injection, and auto failover to alternate sites if needed.
