Three-way Meet Me Audio Conferencing service configuration
Ad Hoc system scalability and expansion
The Ad Hoc service has no built in limitations on how many simultaneous
conferences can exist on the system or how many participants can be
in each conference. The maximum number of participants in a single
conference is limited only by the number of channel licenses purchased,
the capacity of the scaled system, or both. Conferences have no explicit
guaranteed minimum or maximum port limits. Ports are allocated on a
first-come, first-served basis until the license keys are exhausted or available
capacity is exceeded. The overall Ad Hoc service must be engineered to
account for server capacity (that may be limited by licensing). The system
should be over engineered given the unpredictable usage patterns of ad
hoc conferences.
The Media Application Server provides scalability across multiple machines
through system-level replication. The Media Application Server platform can
scale from a small single-machine solution to a large multi-machine cluster.
The Media Application Servers are grouped together as a Pooled Entity
service instance. To meet expanding capacity requirements, new Media
Application Servers can be added to an existing Pooled Entity. In addition,
multiple pooled entities can be created, each consisting or one more Media
Application Servers.
