1.4 Relationship to Other Protocols

Session Multiplex Protocol (SMP) depends on an underlying reliable stream-oriented network transport. Optionally, Transport Layer Security (TLS)/Secure Sockets Layer (SSL) [RFC2246] [RFC6101] can be inserted between SMP and the transport layer to provide data protection.

The Tabular Data Stream (TDS) protocol, as specified in [MS-TDS], depends on SMP when the Multiple Active Result Sets (MARS) [MSDN-MARS] feature is specified. TDS is an example of a higher-layer protocol for SMP. This dependency is illustrated in the following diagram.
