Direct Access File System (DAFS) is a network file system that is based on NFSv4 and the Virtual Interface (VI) data transfer mechanism.
This lowers latency by reducing the number of steps needed to process and transfer remote data.
With the draft release of v1.0, it was then passed to the Internet Engineering Task Force (IETF).
The same year, a working version of DAFS was demonstrated using the Oracle database.
[3][4] DAFS beta version 1.0 is available from SourceForge under the BSD license.
