For unicast messages, SRMP MUST be carried out over [SOAP1.1] and HTTP 1.1 [RFC2616]. Both the sending and the receiving sides MUST provide Web services with the following capabilities:

  • Support for SOAP (as specified in [SOAP1.1]) over HTTP 1.1 (as specified in [RFC2616]) over TCP/IP.

  • Support for HTTPS for securing communication with clients.

Each Web service SHOULD<1> expose the following TCP ports as endpoints for the HTTP over TCP/IP transport:

  • Port 80: The default HTTP port.

  • Port 443: The default HTTPS port for secure communication using Secure Sockets Layer (SSL) [RFC2818].
