SQL Server Protocols

The Microsoft SQL Server Protocols documentation contains detailed technical specifications for Microsoft protocols that are implemented and used by SQL Server to interoperate or communicate with other Microsoft products. It also contains technical specifications for extensions to industry-standard and other published protocols that are used by SQL Server. In addition, the documentation set includes a companion overview document that supplements the technical specifications with conceptual background information, overviews of inter-protocol relationships and interactions, and technical references.

Although the Open Specifications technical documents are freely available, many of them include patented inventions. Some of these patents are available at no charge under the Open Specifications Promise or the Microsoft Community Promise. The remaining patents are available through various licensing programs. For more information, please visit the Microsoft Open Specifications Dev Center website or send an email message to the IP Licensing Team.
