Switched Ethernet is widely used for all kinds of applications. However, for demanding multimedia streaming applications in a fully-loaded network, legacy Ethernet is not the best choice due to its limited Quality-of-Service (QoS) support. The new specification of the IEEE 802.1 Audio/Video Bridging (AVB) standard, an extension to legacy Ethernet, provides the QoS features needed for multimedia streaming: Time synchronized low latency streaming services and bandwidth reservation on Layer-2. In this work, we study and analyze the AVB standard based on a simulation approach to verify the specified constraints and to determine the feasibility of the mechanisms in a switched Ethernet network. We use the simulation tool OMNeT++ and extend the existing INET-framework to support all the required protocols specified in the IEEE 802.1 AVB standard.
