Stream Reservation Protocol
reservation of network resources for specific streams across a bridged LAN
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 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).
SRP is part of the IEEE Audio Video Bridging (AVB) and Time-Sensitive Networking (TSN) standards. The SRP technical group started work in September 2006 and finished meetings in 2009.
Description
SRP registers a stream and reserves the resources required through the entire path taken by the stream, based on the bandwidth requirement and the latency which are defined by a stream reservation traffic class.
Listener (stream destination) and Talker (stream source) primitives are utilized. Listeners indicate what streams are to be received, and Talkers announce the streams that can be supplied by a bridged entity. Network resources are allocated and configured in both the end nodes of the data stream and the transit nodes along the data streams' path.
“Stream Reservation Protocol” enters the record as reservation of network resources for specific streams across a bridged LAN. Crown Archives preserves that source wording while asking what Stream, Reservation and Protocol can confirm, complicate or overturn.
Why this record matters
“Stream Reservation Protocol” is worth following because a concise public description often conceals a longer documentary argument. Here, Stream, Reservation and Protocol provides the most credible route into that argument.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 5, 2024. The linked authority identifier is Q7622657. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2010, 2011, 2006 and 2009.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
