I believe that the situation is more complex than this. I am only personally aware of embedded systems using IPv4 at this time. Nevertheless, I do not think that embedded systems are an IPv4-only domain because certain industries are talking about deploying non-IPv4 networks. For example, in civil aviation, the current air-to-ground digital communication target is the Aeronautical Telecommunications Network (ATN), which is an OSI (CLNP/TP4) network. ICAO is talking about soon creating an IPv6 variant to ATN. However, I have not heard anybody mention an IPv4 variant.
Given this, what protocol will a future onboard collision-avoidance system use? Would it natively use IPv4 that is translated or encapsulated into either OSI or IPv6 for off-board communications, if any? Would it natively use either OSI or IPv6? Would it do something else? -----Original Message----- From: Randall Atkinson [mailto:[EMAIL PROTECTED] Earlier Eric F wrote: % I'd like to point out that an large number of embedded system devices % are increasingly using IP networks for their communications. How many of these are both (1) end-of-maintenance and (2) has IPv6 implemented and enabled today ? My guess is that the intersection of those 2 items is zero. For the US DoD, everyone who should know tells me that (2) by itself is either zero or tiny. Is this really an IPv4-specific consideration ? So if approach A were taken for IPv4 and approach B for IPv6, then B could be designed without this issue ?
