+Multiple Clusters In Same Network
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+It is possible to create multiple clusters in the same physical or logical
+network. Each such cluster must have a unique name, this does not only helps
+admins to distinguish on which cluster they currently operate, it is also
+required to avoid possible clashes in the cluster communication stack.
+
+While the bandwidth requirement of a corosync cluster is relatively low, the
+latency of packages and the package per second (PPS) rate is the limiting
+factor. Different clusters in the same network can compete with each other for
+these resources, so it may still make sense to use separate physical network
+infrastructure for bigger clusters.
