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. See 

The Polycom RealPresence DMA system uses site topology information for a variety of purposes, including 
cascade for bandwidth conferences, bandwidth management, Session Border Controller selection, and 
cluster responsibility management in a supercluster. It can get it in one of two ways: 

● If you have a Polycom RealPresence Resource Manager or CMA system, integrate the Polycom

Note: Network Topology and Site Topology Could Differ
Site topology information provides a logical model representation of a network topology, not 
necessarily a fully accurate literal representation of a full network.
