Unicast Push Stream Method
The SME 211 supports one UDP/RTP push stream and one RTMP push stream per
encoder.
Available Multicast Streams
The SME 211 uses the IGMP multicast protocol to push or pull streams. The IGMP multicast
protocol provides increased bandwidth efficiency because network equipment is able to
manage the traffic efficiently when correctly configured. All network switches and routing
equipment must be properly configured to support IGMP snooping, IGMP querying, and
multicast filtering to avoid flooding all endpoints with unnecessary streaming traffic.
The table below indicates the approximate number of multicast streams supported by the
SME 211 using the IGMP multicast protocol. Operating at different resolutions using higher
or lower bit rates can increase or decrease the scalability of the streaming system.
NOTE: For networks not configured to use the IGMP multicast protocol, consider using
a media server to deliver multiple unicast streams to control PCs and viewing devices.

NOTES: The number of available pull streams is dependent on bandwidth and content
(high motion or static content).
The following configuration options were set on the SME:
•
Stream Type = VBR
•
GOP Length = 30
•
Streaming Pull Streaming Method = Unicast RTP at default settings
If more streams are required, set up a media server to expand the streaming architecture. A
media server provides a scalable live streaming media solution.
Multicast Push Stream Method
The number of multicast push streams is not limited.
