A Resource Reservation in 802.1AVB

Many research efforts have been conducted to achieve the transmission of real-time traffic over the Ethernet network. The standardization of network techniques for real-time traffic over Ethernet is well into progress for IEEE 802.1 AVB TG. In this paper, Active MSRP based on IEEE 802.1Qat is proposed. Active MSRP can handle bandwidth reservation for time sensitive traffic in various reservation failure scenarios. Therefore, Active MSRP adaptively releases bandwidth, thus making it is more efficient for network utilization than IEEE 802.1Qat. Active MSRP was compared with IEEE 802.1Qat through OPNET network simulation tool.
