Stream Reservation Protocol (SRP)
When a Listener is configured to listen to a specific Talker Stream , the Stream Reservation Protocol (SRP) ensures that the required bandwidth is available on the entire path from the Talker to the Listener. Each Switch checks if the bandwidth is available. If a switch has insufficient bandwidth, the stream will not be established.
If SRP successfully configures a path from Talker to Listener, the Talker starts streaming its data.
It is important to point out that up to 75% of the available bandwidth can be utilized for Milan AVB. It is not reserved per se. If a stream only needs 2% of the available bandwidth, then only these 2% are reserved, and the rest remains available for other traffic.
How much bandwidth is reserved for my audio stream?
The following table provides a quick guide on how much bandwidth is reserved for different combinations of channels and sample rates.
Detailed calculation
The following section summarizes the calculation described in the respective IEEE
specifications.
Follow these steps to calculate the bandwidth required for a given stream configuration
