Name	Type	Description
GtpUserX2	simple module	This module implements a simplified version of the user plane of the GPRS Tunneling Protocol (GTP) used for handover procedures. In particular, it is employed to transfer data packets from the source e/gNodeB to the target e/gNodeB during a handover (i.e., packets destined for a UE that is undergoing a handover). On one hand, this module encapsulates incoming IP datagrams from the local LteX2Manager into GTP packets and sends them over the X2 interface. On the other hand, it receives GTP packets from other e/gNodeBs and decapsulates the included IP datagrams, which are then forwarded to the local LteX2Manager.
