package simu5g.corenetwork.gtp;

//
// Implements a simplified version of the user plane of the GPRS Tunneling
// Protocol (GTP). On one hand, this module encapsulates incoming IP datagrams into GTP
// packets and sends them to the tunnel destination endpoint (GTP operates on top of
// UDP). The destination endpoint is identified by utilizing information from the
// ~TrafficFlowFilter module. On the other hand, when this module receives GTP packets
// from a tunnel source endpoint, it decapsulates the included IP datagram and sends it
// to the intended destination according to normal IP forwarding.
// Used by all entities that need to communicate within the cellular core
// network, such as ~eNodeB, ~gNodeB, ~PgwStandard, ~Upf, and ~MecHost modules.
