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. See Territories.
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.
