ExtClientServerExample with background cells instead of external ones: one gNodeB served by a Upf core, a router in front of the Upf, one NrUe, and numBgCells BackgroundCell cells. The router has no simulated peer: the host it talks to, and the applications on the NrUe, are configured in the ini file.

One gNodeB served by a Upf core, a router in front of the Upf, and one NrUe. numExtCells ExtCell cells can be added as interferers. The router has no simulated peer: the host it talks to, and the applications on the NrUe, are configured in the ini file.

One gNodeB and one MecHost hung off the same intermediate Upf, behind an anchor Upf that carries the Ualcmp and, behind it, the MecOrchestrator, plus one NrUe. Nothing here is external: which node talks to a real host, and over which interface, is configured in the ini file.

One gNodeB served by a Upf core, a router in front of the Upf, and two NrUe terminals. numExtCells ExtCell cells can be added as interferers. The router has no simulated peer: the host it talks to, and the applications on the UEs, are configured in the ini file.

One gNodeB and one MecHost hung off the same intermediate Upf, behind an anchor Upf that carries the Ualcmp and, behind it, the MecOrchestrator, plus one NrUe. Nothing here is external: which node talks to a real host, and over which interface, is configured in the ini file.

One gNodeB and one MecHost hung off the same intermediate Upf, behind an anchor Upf that carries the Ualcmp and, behind it, the MecOrchestrator, plus one NrUe. Nothing here is external: which node talks to a real host, and over which interface, is configured in the ini file.

Two gNodeB cells served by a 5G core: the anchor Upf faces the data network (a router and a server), an intermediate Upf feeds both gNodeBs, and an X2 link joins them. numUe NrUe terminals attach, and numBgCells BackgroundCell cells can be added as interferers.

The two-cell version of SingleCell_withSecondaryGnb: two eNodeB masters, each paired over X2 with its own gNodeB secondary, and a further X2 link between the two masters. Both eNodeBs connect to the EPC PgwStandard, which faces a router and a server; neither gNodeB has a core-network link. numUe NrUe terminals attach, and numBgCells BackgroundCell cells can be added as interferers.

Two gNodeB cells, each on an intermediate Upf of its own with a MecHost hung off it, so every cell has its own MEC host. Both intermediate Upf nodes meet at the anchor Upf, which carries the Ualcmp and, behind it, the MecOrchestrator. An X2 link joins the two gNodeBs. numUe NrUe terminals attach, and numBgCells BackgroundCell cells can be added as interferers.

MultiMecHost with the two intermediate Upf nodes linked directly to each other, and with no X2 link between the gNodeBs. The length of that link -- and so its propagation delay -- follows the routersDelay parameter, which makes the distance between the two MEC hosts configurable.

Two operator networks side by side. Each has three gNodeB cells chained by X2, an intermediate Upf that feeds them and carries the operator's MecHost, an anchor Upf, and a Ualcmp with its MecOrchestrator. The two anchor Upf nodes meet at a shared router, the only node the operators have in common. numUe_A and numUe_B NrUe terminals attach to operator A and B respectively, and numBgCells BackgroundCell cells can be added as interferers.

The topology of SingleMecHost -- one gNodeB and one MecHost on a shared intermediate Upf, with a Ualcmp and a MecOrchestrator behind the anchor Upf -- without its playground size parameters. numUes NrUe terminals attach to the gNodeB.

One gNodeB served by a 5G core: the anchor Upf faces the data network (a router and a server), and an intermediate Upf sits between it and the gNodeB. numUe NrUe terminals attach to the gNodeB, and numBgCells BackgroundCell cells can be added around it as interferers.

SingleCell_Standalone with its UEs split into three vectors, so that a configuration can address cellular terminals (ueCell), D2D transmitters (ueD2DTx) and D2D receivers (ueD2DRx) separately. The rest of the topology is the same: one gNodeB behind an intermediate and an anchor Upf, with a router and a server on the data network, plus numBgCells BackgroundCell interferers.

The mirror image of SingleCell_withSecondaryGnb: here the gNodeB is the master node and the eNodeB is its secondary, so the UE is anchored on its NR stack and its LTE stack carries the secondary cell group. All data-plane traffic enters at the gNodeB.

An EN-DC topology: an eNodeB master paired over X2 with a gNodeB secondary. The eNodeB is the only node with a core-network link -- an EPC PgwStandard facing a router and a server -- so all data-plane traffic enters there, and the gNodeB contributes its radio leg alone. numUe NrUe terminals attach to both, and numBgCells BackgroundCell cells can be added as interferers.

One gNodeB and one MecHost hung off the same intermediate Upf, behind an anchor Upf that carries the Ualcmp and, behind it, the MecOrchestrator. numUes NrUe terminals attach to the gNodeB.

Defines a LteCar node as an NR User Equipment (UE) with vehicular-like mobility. The latter is modeled by utilizing the Veins-Inet project.

Models a User Equipment (UE) in a 4G LTE network. It is a host equipped with an LTE Network Interface Card (NIC), allowing the UE to connect to an eNodeB module via the Radio Access Network (RAN) of the LTE network and communicate with any other host in the system. In addition to a NIC submodule, this compound module includes all the higher layers of the protocol stack, from IP to application modules. It supports a configurable number of UDP and TCP applications. It also features an Ethernet interface, which is utilized in real-time emulation mode to connect the UE to the real network (outside the simulator) via a virtual Ethernet interface.
