I've been a silent subscriber of this list for quite a long time
now, and this discussion has finally prompted me to post. I've
been a designer of protocols (app level and asynch mostly), and
an avid student of internetworking protcols from TCP/IP to OSI.
I'm curious: Are there mailing lists and/or newsgroups dedicated
specifically to the discussion of networking protocols for
packet radio? Is there a contender for AX.25? (Is there a list
that is not Linux specific is, I guess, one way of putting it).
Now, as for Linux specifically, one element of ICMP that very few
protocol stacks I have directly studied (and Iplease note I have yet
to delve into Linux kernel code -- I'm sure many here have) pay
any attention to is ICMP source quench messages. Perhaps by making
use of this feature we can distinguish between congestion and
packet loss? ICMP Source Quench could be used to go immediately
to a slow start, while packet loss could perhaps follow the more
traditional linear back off?
Well, back to lurking...
