1.4 Relationship to Other Protocols

The Provider Framework protocol uses SOAP messages to format the requests and responses as specified in [SOAP1.2-1/2007] and [SOAP1.2-2/2007]. These SOAP messages are encrypted by the TcpTransportBindingElement Class described in [MSDN-NETTcpBE] and sent over the .NET Message Framing TCP Binding Protocol [MS-NMFTB], which is built on top of the TCP/IP protocol.
