GtpEndMarkerInd

class

Marks a packet that stands for a GTP-U End Marker (TS 29.281 7.3.2): the end of a PDU session’s downlink on the tunnel it arrived on, which the anchor sends at the path switch. It carries no data. The old base station relays it over X2 to the base station the UE moved to, which releases the downlink it has held back from the new path until then (see HandoverPacketHolderEnb). Attached by GtpUser and GtpUserX2 where the End Marker arrives; node-local, like SessionTag.

HttpBaseMessage

class

Base class for HTTP messages

HttpRequestMessage_m

class

Message class for HTTP requests

IpHeaderFieldsTag

class

The fields of a user-plane packet’s IP header that a node classifies and routes by, parsed once where the packet enters the node’s user plane (see attachIpHeaderFields()) and read by every later module of the node instead of the header itself, so a missing entry point aborts rather than silently re-parsing.

SequenceNumberInd

class

Indication tag containing PDCP sequence number for packet ordering Usually sent by PDCP to RLC layer.

SessionTag

class

The session a downlink datagram belongs to at a base station, and so the UE it is for. It is attached where the datagram enters the base station: from the GTP-U tunnel it arrived on, from the core network (GtpUser) or from a handover source (GtpUserX2), or, on the shortcut between two UEs of the same base station (TrafficFlowFilter’s fastForwarding), from the destination UE’s session (GtpUser). The modules after the entry read the UE from this tag, and each applies its own policy for picking one of the UE’s node ids (see HandoverPacketHolderEnb, Ip2Nic). The tag also carries the session’s type, as the tunnel end knows it from the session’s establishment, so no module after the entry has to parse the datagram to learn what it carries. A datagram forwarded to a handover target keeps it until GtpUserX2 sends it on the session’s tunnel there.

UplinkUeTag

class

At a base station: the UE an uplink datagram was received from over the air, by the node id the base station’s stack knows it by. Attached where the datagram leaves the radio stack (Ip2Nic) and consumed where it enters the uplink tunnel of the UE’s session (GtpUser), so the tunnel is chosen by the UE the datagram came from, whatever its payload.
