Introduction to 5G simulation with NetSim

NetSim 5G NR Library allows for end-to-end simulation of all layers of the protocol stack as well as applications running over the network. The 5G devices available in NetSim are the 5G core devices: (i) AMF, (ii) SMF, (iii) UPF, and RAN devices: (i) gNBs (ii) UEs. The Simulation is a discrete event and done at a packet level abstraction. This 5G library is designed to connect to the base component of NetSim (and in turn to other components), which provides functionalities such as the TCP/IP Network Stack, Routing algorithms, Mobility, Output Metrics, Traces etc. NetSim’s protocol source C code shipped along with (Standard / Pro versions) is modular and customizable to help researchers to design and test their own 5G protocols.
