2.2.1 RDP-UDP2 Packet

This section describes the bitmap overview of an RDP-UDP2 Packet and how it is constructed, as well as the message syntax for the various structures used in the construction of the RDP-UDP2 Packet.

The following bitmap shows the memory layout of the mandatory RDP-UDP2 Packet Header and the optional payloads that form the RDP-UDP2 packet. It also shows the ordering of various optional payloads when more than one optional payload is present. This ordering MUST be followed when sending multiple optional payloads in an RDP-UDP2 packet.
