Keith,<br><br>
I'm sorry I never got through the whole book. I see in your
new edition that a few of my comments were addressed ( you got rid of
services....I had lots there!). Here are some comments, which I
know are late and you can ignore if you so choose.<br><br>
A couple of general comments:<br>
- There are some "we" or "first person" in the
document that I think should be removed/reworded (i.e. 3.1.1)<br><br>
- The document is pretty heavy on detail, which is nice in one way,
but for a Green Book I think there's too much. You're also giving
solutions, i.e. DiffServ. IPSec, etc., where I think that info is more
suitable in a Recommendation (Red/Blue) or Recommended Practice
(Magenta). There's so much information, I found it hard to look at
the simple picture.<br><br>
Some specific comments:<br>
Section 1.6 Scope - right after FIgure 4. The word
"prescribed", should probably be "recommended".
<br><br>
Section 3.6 is open-ended.... Maybe it was Microsoft, but the
latter half of the paragraph seems to be missing.<br><br>
Section 4.3 paragraph 2. If you are referring to the QoS parameter
in the frame header, I would argue that this is insufficient for onboard
traffic. Could possibly be used in conjunction with other QoS
scheme, not good enough on its own.<br><br>
4.3 last paragraph. The example I think is weak. I better one
would be an app using 1553 to get data from a sensor, where it would be
inefficient to go through a network.<br><br>
Section 4.4.1 last paragraph - does using SCPS through
network-layer gateways require any type of custom code/support?<br><br>
Section 4.6.3 What is NASA’s security policy? If it does not
include IPSec, does that mean we can never conform to IPv6?<br><br>

what I think is (nearly, I know of at least one figure that needs to be
tweaked) the final version before we submit to CESG in CWE
