Project Title Developing the Carrier Ethernet based AVB(Audio Video Bridging) Switch
Term 2012 ~ 2015 Funding Ministry of Science, ICT and Future Planning
Target Implementing broadband multi-media Ethernet switches for buildings, cars, etc.
Key Technology AVB protocol (IEEE 802.1BA, 802.1Qav, , 802.1Qat , 802.1AS)
MEF CE 2.0 Compliant
Overview The AVB network structure does not require changes to the Ethernet lower layers and is compatible with all other functions of standard Ethernet switches. Ethernet is the most dominant form of Local Area Network (LAN) technology on the market today. Standard Ethernet and Ethernet bridging (switching) are not suitable for the transmission of real-time audio and video as Ethernet frames are subject to unpredictable frame loss and unacceptable latency variation. The requirement to be able to transport various kinds of real-time and non-real-time data over Ethernet (each with their own unique resource requirements) requires some enhancement to be made to standard Ethernet and Ethernet bridging. This project explores the role of Ethernet in one such emerging market, the professional AV industry, in which the AVB set of IEEE 802.1 standards is simplifying and lowering the cost of implementations that traditionally have been characterized by complexity, expense, and lack of interoperability.
