Abstract
This technology enables prioritization of Multiple Stream Reservation Protocol ('MSRP') transmissions in Audio Video Bridging ('AVB') virtual local area networks (“VLANs”). An AVB switch receives a status from listener devices, associates a state with each of the statuses indicating whether each listener device is active or in-active, and stores each state in a database. For each listener device, a queue of MSRP protocol data unit (“PDU”) packets exists to be transmitted to the listener device. The AVB switch searches the database for listener devices with an active state, searches the queue for each active listener device for packets associated with an active state, and transmits the packets associated with the active state to each active listener device. Subsequently, the AVB switch searches each listener device's queue for packets associated with an in-active state and transmits the packets associated with an in-active state to each listener device.
