Configuring Stream Groups
A Stream Group consists of one or more Streamers. Streamers within a Stream Group work as a team
with regard to content caching, load distribution, and bandwidth usage. Stream Groups interact with
other Stream Groups by passing streams among each other based on performance qualification and cost
considerations. If a Stream Group must give up a stream to another group, Stream Group preferences set
on the QAM Gateway page are followed. Stream Groups relate to QAM gateways or destination
subnetwork by the Stream Group preference. For more information about Stream Group and QAM
gateway associations, see the “Configuring QAM Gateways” section on page 4-4. For more information
about destination subnetworks and Stream Groups, see the “Configuring Stream Destinations” section
on page 4-17.
A Streamer can never be a member of more than one Stream Group.
