Project Overview

The Brussels Project provides a standardized interface for configuring all GLDv3 nics via dladm, by extending and exploiting the existing GLDv3 framework to provide a much-needed, and vastly improved, Stable Interface for datalink drivers that have previously used ndd to dynamically modify parameters.

In addition to providing a frame-work for the configuration of datalink driver parameters, Brussels also brings with it

  • persistent property configuration, so that parameter settings are restored when the driver is restarted (a feature notably lacking with ndd(1m))
  • provision for dynamic tuning of many parameters like mtu (which has tradtionally beem tuned with driver.conf(4), with modifications requiring destructive resets like reboot)
  • a uniform name-space for parameters (no more dilemmas like "link_duplex or link_mode?", "half_duplex == 0, or half_duplex == 1"?)

The Brussels Project has putback to Solaris Nevada on Jan 24 2008. The framework should be available in snv_83. Check out Sowmini's blog for details on what's available, and what's coming next down the pipeline.

As we work on converting more drivers to Brussels, we are also evaluating a similar improved configuration method for TCP/IP tunables – any comments, wish-lists, suggestions are welcome! We are also trying to clean up ndd abuse in the TCP/IP layer, and these slides talk about removing one such parameter – tcp_trace.

Here are some reference documents

We have also put together an interactive prototype of our proposed GUI that will eventually be integrated into NWAM – please try it out and send us your input!

feedback is welcome!
