This theory defines policy combinators for those network models which
|
|
have ports. They are provided in addition to the the ones defined in the
|
|
PolicyCombinators theory.
|
|
|
|
This theory requires from the network models a definition for the two following constants:
|
|
\begin{itemize}
|
|
\item $src\_port :: ('\alpha,'\beta) packet \Rightarrow ('\gamma::port)$
|
|
\item $dest\_port :: ('\alpha,'\beta) packet \Rightarrow ('\gamma::port)$
|
|
\end{itemize}
