\frametitle{White Rabbit Compliance and Performance Tests}
\section{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.

{Do we need it?}
{Missing Tests}
\begin{itemize}
\item Throughput
\item Latency
\item Frame Loss Rate
\item System Recovery
\item Synchronization performance with multicast traffic
\item etc...
\end{itemize}
\end{block}
\begin{block}
{Do we need this tests?}
\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?
\end{itemize}
\end{block}
\begin{block}
{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.
\end{itemize}
\end{block}
\begin{block}
{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...
