 # The Network Control Plane
 
-The Network Control Plane (NCP) is the gateway to the control plane. Any node
-may join the control plane. It is when nodes need to ensure information is

-using a gossip protocol.
+The Network Control Plane (NCP) acts as a gateway to nodes in the control
+plane. Fullnodes use the NCP to ensure information is available to all other
+nodes in a cluster. The NCP broadcasts information using a gossip protocol.
 
 ## Gossip Overview
 
-Nodes continuously share signed data objects among themselves in order to find
-each other, structure the network data plane, prevent censoring, etc.
+Nodes continuously share signed data objects among themselves in order to

+height, and votes.
 
-The basic mechanism is a 10Hz loop wherein every node sends a push message
-and/or a pull message.  Push and pull messages may elicit responses, and push
-messages may be forwarded on to others in the network.
+Every tenth of a second, each node sends a "push" message and/or a "pull"
+message.  Push and pull messages may elicit responses, and push messages may be
+forwarded on to others in the cluster.
 
 Gossip runs on a well-known UDP/IP port or a port in a well-known range.  Once
