Time Synchronization and Resource Reservation for Time-Sensitive Applications in Bridged Local Area Networks

With the growth of digital media devices, researchers are developing techniques for transmission of real-time trafficover the network. Above all, network techniques that utilize Ethernet are in the limelight because of the advantages of Ethernet. A standardized network technique for isochronous traffic over Ethernet is in progress in IEEE 802.1 Audio/Video Bridge Task Group (AVB TG). This paper proposes a network technique for real-time traffic over an Ethernet model, that is, a AVB model with a synchronization method between devices. This paper proposes time synchronization and resource reservation for transmission of real-time traffic in synchronized devices. In this paper, we implement a AVB model through OPNET, and analyze the efficiency of the proposed methods.
