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 on page 294.

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.

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 RealPresence DMA system with it (see Resource Management System Integration on page 178) to automatically get its site topology information.
