To provide all client features to users, plan to deploy Sametime® Community Servers and Sametime Media Manager components.
|
Components used
The following components must be deployed in a Sametime environment that combines instant messaging and presence enabled and audio and video features:
-
Sametime System Console - used for managing and administering servers from a central location
-
DB2®
-
LDAP directory
-
Sametime Community Server
-
Sametime Connect client, Sametime client embedded in Notes®, or Sametime browser client
-
Sametime Media Manager - provides audio and video features in the Sametime client and in meetings
The following components can optionally be deployed:
-
Sip Edge Proxy server - used to negotiate SIP traffic to Sametime Sip Proxy/Registrar deployed behind NAT / Firewall
-
Sametime Bandwidth Manager - enables you to assign maximum levels of bandwidth usage to users based on policy settings
-
Sametime TURN Server - enable clients to exchange audio and video data when direct peer-to-peer communications are not possible
-
Sametime Proxy Server - provides an integrated web chat client and presence; required for Sametime browser clients
Audio-visual components provided with the Sametime Media Manager
The Sametime Media Manager comprises three components, which are installed on separate systems in a production environment.
Based on voice-activated switching, the Packet Switcher functions as an MCU (Multipoint Conferencing Unit) by routing audio and video data between participant endpoints. There can be one or more Packet Switchers in a deployment; the Conference Manager will distribute conferences over the available Packet Switchers. A Packet Switcher can only be registered with one Conference Manager (or cluster of Conference Managers). A Packet Switcher should not be a member of a WebSphere Application Server cluster; instead, each Packet Switcher is deployed as a non-clustered (primary) node.
Manages multipoint conferences by maintaining a dialog with each participant, and ensuring that all media flows between those participants. You can install multiple Conference Manager components and cluster them for high availability and failover.
Directs conference participants to Conference Manager servers and provides high availability and failover functionality. You can install multiple SIP Proxy/Registrar components and cluster them for high availability and failover.
