426 CHAPTER 8 Networks

A more distributed approach to avionics is the federated network. In this

architecture, a function or several functions have their own network. The networks

share data as necessary for the interaction of these functions. A federated architec-

ture is designed so that a failure in one network will not interfere with the operation

of the other networks.

The Genesis Platform [Wal07] is a next-generation architecture for avionics and

safety-critical systems; it is used on the Boeing 787. Unlike federated architectures,

it does not require a one-to-one correspondence between application groups and

network units. In contrast, Genesis ...
