1.5 Prerequisites/Preconditions

The Remote Desktop Protocol: Geometry Tracking Virtual Channel Extension operates only after the dynamic virtual channel transport is fully established. If the dynamic virtual channel transport is terminated, no other communication over this protocol extension occurs.

This protocol is message-based. It assumes preservation of the packet as a whole and does not allow for fragmentation.  Additionally, it assumes that no packets are lost.

It is assumed that the visible regions of all geometries sent from the server are non-overlapping. If there are any regions that overlap, then the z-order of those regions will be non-deterministic.
