{
White Rabbit Compliance and Performance Tests
}
Integrasys has done the following compliance tests:
\begin{itemize}
\item
VLAN support
\item
MRP and MVRP
\item
Remote Management Interface
\end{itemize}
CERN (Maciej Limpinsky) has "tortured" the switch and measured the
synchronization performance between 0 and 50 degrees.

\begin{itemize}
\item
Would commercial solutions fulfil our tests?
\item
Could community afford to buy/rent commercial solutions?
\item
Do we need a way of verifying that a combination hw+firmware achieves
the White Rabbit features?
\item
This test could detect new issues in the v3
gateware/firmware/design
\item
Do we need a standardized way of verifying that a combination hw+firmware achieves the White Rabbit features?

{
Do we need special hw and which one?
}
\begin{itemize}
\item
Commercial solutions cover partly our tests
\item
The community could hardly afford to buy/rent a commercial
solutions. For the manufacture it could be seen as an investment.

{
Proposal
}
\begin{itemize}
\item
Use the WR Switch hw platform for developing a compliance and performance
tester.
\item
We could reuse part of the current gateware/firmware, but that
tester. It could be also used as a network debugger in production
systems.
\item
We could reuse part of the current gateware/firmware of the switch, but that
wouldn't be enough,it is a new development...
