PFDF - Packet Flow Description Function

Used within CIoT (Cellular Internet of Things) networks, the PFDF is a repository which stores PFD (Packet Flow Description) that can be managed and updated by third party service providers. For example, an IoT platform may require all its associated devices to send information to a new IoT Application Server and thus would provide it with an IP address, protocol and port number to use.
