What is TDS?The Tabular Data Stream (TDS) protocol is an application layer request/response protocol that facilitates interaction with a database server and provides for the following:

• Authentication and channel encryption negotiation.

• Specification of requests in SQL (including Bulk Insert).

• Invocation of a stored procedure or user-defined function, also

known as a remote procedure call (RPC).

• The return of data.

• Transaction manager requests.

Transport LayersThe TDS protocol does not prescribe a specific underlying transport protocol to use on the Internet or on other networks. TDS only presumes a reliable transport that guarantees in-sequence delivery of data.

The chosen transport can be either stream-oriented or message-oriented. If a message-oriented transport is used, any TDS packet sent from a TDS client to a TDS server MUST be contained within a single transport data unit.

The current version of the TDS protocol has implementations over the following transports:

• TCP [RFC793].

• A reliable transport over the Virtual Interface Architecture (VIA) interface [VIA2002].

• Named Pipes [MSDN-NP].

• Shared memory [MSDN-TDSENDPT].

Transport Layers

TDS

Network Transport(TCP/IP)

Optionally, the TDS protocol has implementations for the following two protocols on top of the preceding transports:

• Transport Layer Security (TLS) [RFC2246]/Secure Socket Layer (SSL), in case TLS/SSL encryption is negotiated.

• Session Multiplex Protocol (SMP) [MC-SMP], in case the Multiple Active Result Sets (MARS) feature [MSDN-MARS] is requested.
