Introduction to the Polycom DMA System
1
The Polycom DMA system is a highly reliable and scalable multipoint
conferencing solution based on the Polycom ® Proxias application server. It
uses advanced routing policies to distribute audio and video calls across
multiple media servers (MCUs), creating a single seamless resource pool. The
Polycom DMA system essentially acts like a single large MCU, greatly
simplifying video conferencing resource management and improving
efficiency.
The Polycom DMA system integrates with your enterprise directory,
automating the task of provisioning users for video conferencing. Combined
with its advanced resource management, this makes ad hoc video
conferencing on a large scale feasible and efficient, reducing or eliminating the
need for conference scheduling.
The Polycom DMA system’s ability to handle multiple MCUs as a single
resource pool makes it highly scalable. To expand the system, you can add
MCUs on the fly without impacting end users and without requiring
re-provisioning.
The Polycom DMA system is designed to have no single point of failure within
the system that could cause the service to become unavailable. To support this,
the system is configured as a cooperative active/active two-node cluster. Both
servers are actively registered and can accept and process calls.
