+Besides being a tractable size for analysis, 16 nodes is also a fairly
+good approximation of actually deployed mixnets. (Mixminion currently
+has between 20 and 30 active nodes.) One might argue that a 4 node mixnet
+provides better security, because all the messages are mixed together
+in any topology. We assume a larger network is needed because 1) the
+bandwidth of a single node may be insufficient to handle all the traffic;
+2) a single path may not include as many choices for jurisdiction as
+some users want; and 3) a single path is not very robust, either to
+network attacks or to nature.
+
+Messages proceed through the network in \emph{layers}; all of the
nodes in a layer process messages of one mixnet batch at the same time.
In general we describe networks as $w$x$\ell$, where $w$ is the number
of nodes at each layer and $\ell$ is the number of nodes in a path.
