Also provided is a mechanism for end-to-end management of the streams' resources, to guarantee quality of service (QoS).
[1] SRP is part of the IEEE Audio Video Bridging (AVB) and Time-Sensitive Networking (TSN) standards.
For credit-based shaper defined in IEEE 802.1Qav, Stream Reservation Class A is the highest, with worst-case latency requirement of 2 ms, and a measurement interval (maximum transmission period) of 125 μs; Class B has the second highest with worst-case latency of 50 ms, and a measurement interval of 250 μs.
SRP essentially operates in the following sequence: A station (talker) sends a reservation request with the general MRP application.
Then each bridge within the same SRP domain can map, allocate, and forward the stream with the necessary resources by using the MRP attribute propagation.
