U-Net: A User-Level Network Interface Architecture


The U-Net architecture provides low-latency and high-bandwidth communication over commodity networks for workstations and PCs. It removes the large communication overheads found in the standard networking layers in the operating system. U-Net defines an architecture which allows network interfaces to be mapped directly into user-space without compromizing protection. With U-Net the operating system is no longer involved with the sending and receiving of messages. This allows a much tighter integration of computation and communication with the effect that communication overheads are reduced dramatically.

U-Net is available on several platforms:

Funding for the project is provided through a DARPA ITO contract (ONR contract N00014-92-J-1866). The initial versions of U-Net were developed under contract F30602-94-C-0224 from Rome Laboratory, Air Force Material Command.
