3 Protocol Details
This section describes the important elements of the client software and the server software necessary to support the SQL Server Resolution Protocol.
As described in section 1.3, the SQL Server Resolution Protocol is an application-level protocol that is used to query information regarding database instances on one or more servers. The protocol defines a limited set of messages through which the client can make a request to the server or servers. The SQL Server Resolution Protocol involves a single request and a single response from one or more servers. The response contains instance-specific values provided by the higher layer.
