NrSdap Class Reference¶

NrSdap implements SDAP functionality.

For PDUs received from the PDCP layer, extracts SDAP headers (if present), restores the associated QoS Flow based on QFI, and forwards the resulting SDUs to the upper layer (IP, Ethernet, or application for unstructured sessions).

For SDUs received from the upper layer, performs QFI-to-DRB mapping, encapsulates the data with SDAP headers if needed, and forwards the packets to the PDCP layer.

A received packet goes up as the protocol the type of its bearer's session implies, which the pushed DRB configuration carries (see DrbDesc::sessionType).
