-As can be seen from the figure, the setup consists of one gNodeB and one UE unit and the two sandbox 1 servers (in this case srv3-lg1.sb1.cosmos-lab.org and srv4-lg1.sb1.cosmos-lab.org). The first server (srv3-lg1) acts as a gateway while the second one is acting as a UE computing platform (to which a UE modem is attached). The 5G Platform devices and the nodes are connected to the sandbox 1 data 1 network and relies on IP routing to ensure that the traffic flow from the client follows the dashed red line in the figure. The intended route is divided into three segment (IP subnets):
