Vertex groups consist of 1 or more Vertex controllers. Vertexes in a group communicate internally with each other in the group with peer to peer (server/client) communication. A Vertex controller in a group ‘sees’ (knows only of the existence of) other Vertexes in the same group. Commands from other Vertex groups are not present, which reduces traffic on this internal XMPP bus. Communication between groups is still possible. This is done via TCP/IP communication and is slightly slower in speed. Using groups is an optimization of communication, where you can separate and limit communication between floors, areas, etc.
Vertex cluster is a system of up to 25 Vertex controllers. Communication between clusters is done via TCP/IP. All Vertexes in one cluster share the same cluster ID - CUID (a Node.js based identifier with collision-resistant communication). Vertexes in a cluster can be divided into groups.
