Stream Reservation Protocol

Abstract: An enhanced stream reservation protocol comprising a Talker device sending a Stream Reservation Protocol (SRP) Talker Advertise message for streaming data to a Listener device, receiving the Talker Advertise message and checking bandwidth availability on an output port thereof for the streaming. In case of insufficient communication bandwidth, sending a failure message that includes information about available bandwidth from the Talker device to the Listener device. A protocol for communication in a bridged network, comprising a Talker device sending an SRP Talker Advertise message for streaming data to a Listener device. The Talker Advertise message includes communication path information from the Talker device to the Listener device. A communication path from the Talker device to the Listener device is selected based on said path metrics, for streaming data between the Talker device and the Listener device.

Abstract: A listener system, or listener, may be used with an Ethernet Audio-Video Bridging ("AVB") network. The listener may include various components, such as an upper layer application and a stream reservation protocol stack. The upper layer application and stream reservation protocol stack may be in communication with each other. The stream reservation protocol stack may receive stream advertisements on or across the Ethernet AVB network. The stream reservation protocol stack may operate in a sparse mode and may operate in a full mode. When operating in a sparse mode, the stream reservation protocol stack may transmit one subset of the received stream advertisements to the upper layer application, and may not transmit another subset of the received stream advertisements to the upper layer application.

Abstract: A system that includes a talker, a listener, and a controller may communicate over an Ethernet Audio/Video Bridging network. The controller may communicate control messages to manage data streams between the talker and the listener through one or more application layer interfaces of the talker and the listener. Based on the control messages, the talker and the listener may communicate using a Stream Reservation Protocol to reserve connection for, or remove connection from, the data streams. The talker and listener may communicate the success of reserving or removing the connections to the controller through the application layer interfaces.

Abstract: The amendment of medium access control (MAC) in 802.11 has been published as the 802.11aa standard. The new standard enhances the quality of service (QoS) provisioning for robust audio–video (AV) streaming in wireless local area networks (WLANs). The 802.11aa standard is mainly an extension of the 802.11e, 802.11n, and 802.11v standards. In this survey, we describe the mechanisms of Medium Access Control (MAC) in 802.11aa in greater detail. The interworkings of the different network technologies of Quality of Service (QoS) WLAN and Ethernet are explained. We add mechanisms from the 802.1Q standard to complement 802.11aa regarding the stream reservation protocol and strict priority algorithm to provide a complete vision of the standard. Research challenges include incorporating a wide range of mechanisms in the 802.1Q wireline standard in the 802.11aa wireless standard. To enhance the interworking of the 802.1Q and 802.11aa standards, we propose to unify three mechanisms: the maps Access Categories (ACs), the transmit access queues, and transmission selection algorithm. This survey provides necessary guidelines for researchers and designers to implement future Wireless Local Area Network (WLAN) 802.11aa with an emphasis on the requirements for robust Audio-Video (AV) streaming.
