¿µ¹®³»¿ë¿ä¾à The standard describes how to enable flexible network configuration over Ethernet for avionics devices using a typical air digital image transmission bus ARINC 818-2 that provides only point-to-point connections.
The standard describes the process of frame conversion performed on trans- mission and receiving convergence devices with ARINC 818-2 Fibre Channel interfaces and Ethernet interfaces. It describes how ARINC 818-2 Fibre Channel frames containing uncompressed image data are received and forwarded to an asynchronous aircraft Ethernet frame and the Fragmentation process required in this process. It also describes how to receive Ethernet frames for asynchronous aviation to extract fragmented ARINC 818-2 Fibre Channel frames and reassemble them.
However, the uncompressed image data format follows ARINC 818-2 and the Ethernet framing format and transmission method for asynchronous aviation follow ARINC 666-7.
