SDC:R0040

R0040: An SDC SERVICE PROVIDER SHALL include the endpoint reference as defined in[DPWS] in every STREAMING MESSAGE in the wsa:From ELEMENT.

  • MDPWS defines the wsa:From header field as optional. To ensure resolving its origin of a STREAMING packet the wsa:From header as the source IP address might not suffice to do that, especially in cases where multiple SDC SERVICE PROVIDERs operate on a single NETWORK NODE.
