Summary0005750: Size for UADP message not in message
Description

We assume that the transport protocol provides the size of the payload (UADP message). This is necessary at least in case of security (position of signature).

We are silent about this assumption.

If somebody want to use a transport that does not have the size information, the size mus be added to a transport specific header.

Added following clarification in
7.2.2.4 NetworkMessage
7.2.2.4.1 General
The UADP NetworkMessage does not provide the total message size. It is expected that the message size is known from the transport protocol. If the transport protocol does not provide the size of the payload, an additional size information must be added in front of the UADP NetworkMessage for that transport protocol.

Added in OPC 10000-14 - UA Specification Part 14 - PubSub Draft 1.05.28.docx
