Ethernet and TCP/IP networking have made tremendous inroads into military and aerospace embedded architectures over the last several years. It would be very difficult to find a processing element, I/O device, or development asset in the embedded Commercial-Off-The-Shelf (COTS) industry that does not provide Gigabit Ethernet in a prominent I/O role. With Ethernet native in virtually every COTS processing architecture and the overwhelming acceptance of TCP/IP networking in the industry, we can expect Ethernet’s role to only expand.
