2.1 Transport

The Distributed Link Tracking: Workstation Protocol MUST use the RPC protocol sequence "ncacn_np", as specified in [MS-RPCE] section 2.1.1.2.

This protocol MUST use the following named pipes, which are well-known endpoints:

  • \\pipe\ntsvcs

  • \\pipe\trkwks

There is no functional difference between these two pipes. The DLT Workstation server MAY<3> listen on the endpoint named "\\pipe\ntsvcs" and SHOULD listen on the endpoint named "\\pipe\trkwks". The DLT Workstation client MAY use either endpoint name in its calls, but SHOULD attempt to use the "\\pipe\trkwks" endpoint first, and fall back to "\\pipe\ntsvcs" if that fails, as specified in section 3.2.4.1.

This protocol MUST use the following parameters:

  • UUID: The RPC interface UUID value defined in section 1.9 MUST be used.

  • Version number: 1.2.
