Stream Reservation Protocol (original) (raw)

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.
