v1.4.1-sdap
d2976e7

Compatible with OMNeT++ 6.2.0 and INET 4.5.4.

This specialized branch release introduces SDAP protocol support, multiple DRBs
and advanced QoS capabilities to Simu5G for enhanced 5G network simulations.
Please note that future main releases may not include these features or may
incorporate them in a different form, as the primary development focus remains
on architectural refactoring and foundational improvements. The changes were
contributed by Mohamed Seliem (University College Cork), with improvements by
Andras Varga (OMNeT++ Core Team).

Reference paper: "QoS-Aware Proportional Fairness Scheduling for Multi-Flow 5G
UEs: A Smart Factory Perspective". Mohamed Seliem, Utz Roedig, Cormac Sreenan,
Dirk Pesch. IEEE MSWiM, 2025.

New Features:

  • Added an SDAP protocol implementation with reflexive QoS capabilities (NrSdap
    and ReflectiveQosTable modules). Available using the NRUeSdap (UE) and
    gNodeBSdap (gNodeB) node types that contain the NRNicUeSdap and NRNicEnbSdap
    NIC types, respectively.

  • DRB (Data Radio Bearer) support with multi-QFI/QoS handling for realistic 5G
    bearer management simulations. This feature is available using NRUeDrb (UE)
    and gNodeBDrb (gNodeB) node types that contain the NRNicUeDrb and NRNicEnbDrb
    NIC types, respectively. It can be configured using the numDrbs parameter.
    QFI-to-DRB mappings can be defined in a context file (see SDAP's
    qfiContextFile parameter) with 5QI parameters and QoS requirements.

  • QoSAwareScheduler with QFI-based Proportional Fair scheduling using QfiContextManager.
    Enable QoS scheduling with LteMacEnb.schedulingDisciplineDl/Ul="QOS_PF".

  • Better representation of compressed headers in PDCP. (Note that header compression is
    disabled by default; enable using PDCP's headerCompressedSize parameter.)

  • New example simulations: simulations/nr/standalone/omnetpp_sdap.ini and omnetpp_drb.ini,
    each with Standalone, VoIP-DL, and VoIP-UL configurations demonstrating SDAP functionality
    and multi-DRB support with QoS-aware scheduling.
