IMPROVED AVIONIC ETHERNET NETWORK AND METHOD OF TRANSMITTING BLOCKS OF DATA IN THE NETWORK

摘要

An avionics switched full- duplex Ethernet communication Arinc 664p7 network (100) comprising at least two independent elementary networks (Nl, N2), each comprises one or more end systems (ESI) suitable to act as source end systems for data frames transmitted over the network, and one or more end systems (ES4) suitable to act as destination end systems for such data frames. Each elementary network further comprises a switching function block (SW1, SW2) connected between the source (ESI) and destination (ES4) end systems. The Ethernet network is characterized in that one of the source (ESI), destination (ES4) end systems and the switching function block (SW1, SW2) comprises timing means (204) suitable to generate a common piece of timing information to be sent to the other devices of the elementary network in-order to enable the transmission of the data frames over the elementary network by one of the source end systems (ESI).
