The spec in question is contained in the ANX (Automotive Network Exchange)
Release 1 Draft Document and reads as follows:
4.3.2.5 Network edge-to-edge packet latency is defined as the one-way delay
for a packet to traverse an ANX CSP network. The latency for a small packet
measured from edge-to-edge in an ANX CSP network (including edge routers, not
including the access links) shall not exceed 125 msec.
I don't think any flame response was meant, but, I can sympathize with the
frustration of responding to the use of random specs in inappropriate ways with
no regard to the application requirements or user environment.
Can't we all just get along?

Let's cut the flame! I think I was the one mentioning the 125 ms at a
recent NASA Workshop. Let me explain:
The 125 ms was not quoted to show that TCP as a protocol does not work
over GEOs, I know better than this. 125 ms is the number that is quoted
by the Automotive Network Exchange as a Service Level Agreement for
certifying their service providers, it is a Quality of Service issue.
Other providers (AT&T, UUNET etc.) also have 100-150 ms latency
agreements. It is not LEO propaganda, it is a terrestrial network issue.
