Ethernet for avionics

A method for controlling transmissions in an avionics Ethernet network, the method comprising:

• providing periodically a set of data messages, each comprising a set of data variables related to avionics functions,
• transmitting at least one synchronization message onto the transmission medium,
• detecting the beginning of at least one periodically repeating communication time frame comprising a plurality of time-slots of predetermined duration, based on the at least one synchronization message, and
• in each system node to:
• performing scheduled transmissions of said data packets, based on scheduling information relating to a timing table statically allocating to each of said plurality of time-slots a predetermined number of data packets, each comprising a predetermined subset of data messages from said set of data messages.

A computer program product, comprising:

• a non-transitory computer readable medium;
• and
• a program code recorded on the computer readable medium for performing, when said computer programme is run on a computer a method for controlling transmissions in an avionics Ethernet network, the method comprising
• providing periodically a set of data messages, each comprising a set of data variables related to avionics functions,
• transmitting at least one synchronization message onto the transmission medium,
• detecting the beginning of at least one periodically repeating communication time frame comprising a plurality of time-slots of predetermined duration, based on the at least one synchronization message, and
• in each system node:
• performing scheduled transmissions of said data packets, based on scheduling information relating to a timing table statically allocating to each of said plurality of time-slots a predetermined number of data packets, each comprising a predetermined subset of data messages from said set of data messages.
