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 DMA
cluster is responsible. Territories serve multiple purposes in a Polycom
DMA system deployment. See “Territories” on page 302.
