A Network PaP is part of the way how to calculate the priority in case of conflicting PaP-requests and not a path product as Flex-PaP and Fix-PaP. Some successive PaP segments are defined as Network PaP in order that in a first step of the priority calculation only those segments are taken in account.

These two expressions are no specific path products - they describe ways how a Fix-PaP or/and a Flex PaP is used within a request and are not path products.

Feeder/outflow paths are paths that connect the origin / destination point of a freight train with the point where the train starts / ends to run on a pre-arranged path.
