CSS Configuration for Media Servers: Content Routing Rule
Using the content owner you have defined, define a content routing rule for the Unified CVP
Media Servers. CSS offers many balancing types for choosing an active media server. This
application uses the default defined round-robin as the balancing method. Additionally, a
primarySorryServer is defined.

The following content rule implements a layer 5 http round-robin routing rule for two media
servers, with the third server reserved for failover.

CSS Configuration for Media Servers: Keepalive Method
The media servers are standard http servers. CSS supports varying methods of keepalives used
to determine the availability of an individual service.
to determine the availability of an individual service.
For media servers, use the http keepalive method. This will ensure that CSS determines the
availability of a server at the application layer. In order to implement this keepalive method,
the service must identify an available html page which the keepalive will use to determine http
availability. For this reason, in addition to the Unified CVP prompt audio files, the server should
have an available html document defined. The example assumes an “index.html” document is
available on the media servers. The http keepalive method will continuously check for the
availability of this document as a means to determine that the server is alive and capable of
serving documents.

It is essential that all media servers included in a Media Server Content rule contain all of the
Unified CVP audio prompt files intended for use by that content rule to ensure that no matter
which server CSS directs the request to, the prompt file will be available.

CSS Configuration for Media Servers: Keepalive Times
Because these services are directly involved in processing voice calls, the shortest possible
failover and re-activation times are desired. As such, set the following keepalive parameters:
