About Site Topology
Site topology information logically describes your network and its interfaces to other networks, including the 
following elements: 
● Site — A local area network (LAN) that generally corresponds with a geographic location such as an 
office or plant. A site contains one or more network subnets, so a device’s IP address identifies the 
site to which it belongs. 
● Network cloud — A Multiprotocol Label Switching (MPLS) network cloud defined in the site topology. 
An MPLS network is a private network that links multiple locations and uses label switching to tag 
packets with origin, destination, and quality of service (QOS) information. 
● Site link — A network connection between two sites or between a site and an MPLS network cloud. 
● Site-to-site exclusion — A site-to-site connection that the site topology doesn’t permit a voice or video 
call to use. 
● Territory — A collection of one or more sites for which a Polycom RealPresence DMA cluster is 
responsible. Territories serve multiple purposes in a Polycom RealPresence DMA system 
deployment. Se
A freshly installed RealPresence DMA system provides a default site topology with sites, subnets, and a site 
link that allow for endpoint registration and call routing (both multipoint and point-to-point). 
Note: Network topology and site topology can differ
Site topology information provides a logical model representation of a network topology, not 
necessarily a fully accurate literal representation of a full network.
