Site Topology

This chapter describes the following Polycom® Distributed Media

Application™ (DMA™) 7000 site topology configuration topics:

•About Site Topology

•Sites

•Site Links

•Site-to-Site Exclusions

•Territories

•Network Clouds

•Site Topology Configuration Procedures

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 page282.
