Stream Reservation Protocol

Stream Reservation Protocol (SRP) is an enhancement to Ethernet that implements admission control. In September 2010 SRP was standardized as IEEE 802.1Qat which has subsequently been incorporated into IEEE 802.1Q-2011. SRP defines the concept of a streams at layer 2 of the OSI model. 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) group of standards. The technical group started work in September 2006 and finished meetings in 2009.[1]


Listener and Talker primitives are utilized. Listeners indicate what streams are to be received, Talkers announce the streams that can be supplied by a bridged entity.

From these primitives the resources are allocated and configured in both the end nodes of the data stream and the transit nodes along the data streams' path. An end-to-end signaling mechanism to detect the success/failure of the effort is also provided.
