Step 1: Obtain information

Obtain the following information from your contact person at the upstream system:

• The application name and application instance for the source content. (The application instance is also known as the stream or stream key.) There are two sources for a standard-class input, or one source for a single-class input. For information about input classes and their uses, see Channel class and input class. For information about input classes and their uses, see Channel class and input class.

  The operator of the upstream system might already have rules for assigning these names. If not, you might have names that you would like to use. Make sure that you and the operator of the upstream system are clear about these names.

  In this example, the application name and instance name are identical. But they could be different:

  Application name: live, and instance name curling

  Application name: live, and instance name curling

• The public network IP addresses. These are the sets of IP addresses where the source or sources for the content will appear on the public network. You need this information to create the input security group.

  For example:

  • For one source: 203.0.113.19, 203.0.113.58, 203.0.113.25

  • For the other source: 198.51.100.19, 198.51.100.59, 198.51.100.21

  These addresses are the addresses shown in the red boxes in the diagram after this procedure.
