About Cisco Unified Videoconferencing 3515 MCU Topologies

The Cisco Unified Videoconferencing 3515 MCU can work in a centralized or cascaded topology. This

section describes these two options.

In a centralized topology, the Cisco Unified Videoconferencing 3515 MCU performs media processing

for all connected terminals. The Cisco Unified Videoconferencing 3515 MCU can handle multiple

conferences simultaneously.

The Cisco Unified Videoconferencing 3515 MCU allows you to combine two or more conferences

resulting in a larger conference with many more participants. This is called cascading. Cascading creates

a distributed environment that helps reduce the drain on network resources. In addition, the processing

resources required by the Cisco Unified Videoconferencing 3515 MCU are distributed between

participating MCUs. Costly telephone or ISDN line usage can be further reduced with the mediation of

a gateway.

Cascading occurs when one conference with "x" number of participants invites another conference with

"y" number of participants. The two conferences effectively become one large conference. The

bandwidth required across a cascaded conference link is only that of one audio/video stream between

the two conferences. This is significantly less than the accumulated bandwidth of all the participants.

Each separate Cisco Unified Videoconferencing 3515 MCU unit participating in a conference retains

control of its individual conference resources and participants.
