In a Cisco Meeting Server (CMS) deployment, there are several software components that work together to enable videoconferencing, collaboration, and other related functions. CMS supports clustering to provide high availability and resilience. Clustering allows multiple servers to work together as a single entity to share the load and ensure that services continue even if one or more servers fail.
However, not all software components in CMS support clustering. Only certain components are designed to support clustering for resilience only. These components are:
B. Call Bridge: The Call Bridge is the core component of CMS that provides audio, video, and data conferencing services. It is responsible for handling call setup, media processing, and other related functions. In a clustered deployment, multiple Call Bridges work together to provide redundancy and failover capabilities. If one Call Bridge fails, the other Call Bridges can take over without disrupting ongoing calls.
E. Web Bridge: The Web Bridge is another critical component of CMS that enables users to join video conferences using a web browser or mobile device. It provides web-based videoconferencing capabilities and works in conjunction with the Call Bridge to ensure that participants can connect and collaborate seamlessly. In a clustered deployment, multiple Web Bridges work together to provide redundancy and failover capabilities. If one Web Bridge fails, the other Web Bridges can take over without disrupting ongoing conferences.
The other software components listed in the question (Recorder, Database, TURN Server, Streamer, and XMPP Server) do not support clustering for resilience only.
C. Database: The CMS Database stores configuration information, user profiles, and other data related to the CMS deployment. Although the database can be clustered for performance and scalability, it is not designed for resilience only.
A. Recorder: The Recorder is responsible for recording videoconferences and other related events. It does not support clustering for resilience only.
D. TURN Server: The TURN Server is used to relay media between endpoints when direct connections are not possible. It does not support clustering for resilience only.
F. Streamer: The Streamer is responsible for streaming video and audio content to participants in a video conference. It does not support clustering for resilience only.
G. XMPP Server: The XMPP Server is responsible for managing chat and instant messaging services in CMS. It does not support clustering for resilience only.
In summary, the two software components in a Cisco Meeting Server deployment that support clustering for resilience only are the Call Bridge and the Web Bridge.
