Broadcast Server Operation with Clusters

Note

Hardware and Software Overview

In this topic, the term Primary Application Gateway is used to refer to the
last Application Gateway in the cluster that registered with Broadcast
Server. All other Application Gateways in the cluster are referred to as
Secondary Application Gateways. This use of the terms Primary and
Secondary does not imply that clusters support failover for this release.
The Primary Application Gateway (the last server in the cluster that
registers with Broadcast Server) is the one that receives alerts from
Broadcast Server. That Application Gateway then pushes the alert to the
rest of the cluster, the Secondary Application Gateways.
Application Gateway failure impacts Broadcast Server as follows:
When a Secondary Application Gateway in a cluster fails, the phones
•
registered to that Application Gateway will not have access to any
Voice Office applications and will not be able to receive pages or
broadcasts.
When a Primary Application Gateway fails, communication from
•
Broadcast Server to the cluster is halted until one of the Secondary
Application Gateways re-registers with Broadcast Server. To
re-register an Application Gateway with Broadcast Server, restart the
Application Gateway.
For information on setting up a cluster, refer to the Application Gateway
Administration Guide.
Broadcast Server is a software-only solution requiring installation of the
server software on a computer running Microsoft Internet Information
Services.
Once installed on the IIS server, users may access Broadcast Server to
create and manage content to be distributed, via the Application Gateway,
to IP telephones.
Broadcasts are received in the order in which they are sent. If a phone is
busy, a broadcast is queued.
