<title>Cluster Membership Protocol</title>
<h1>Cluster Membership Protocol</h1>
The cluster membership protocol implemented in the
    <a href="sc/cmm">CMM</a>
guarantees that each
    <a href="sc/node">node</a>
of the distributed system agree on the set of nodes that form the cluster. 
This prevents a node from accessing the shared resources, such as the
shared database, without global synchronization. <p>
