[ax25-layer2] OpenTrac layer 3 discussion on OpenTrac-spec list

[Jason Winningham]

I am trying to get a discussion started on a layer 3 network design  
for the OpenTrac protocol.  This is off-topic for the ax25-layer2  
list, so please don't reply here.


The OpenTrac spec, as it stands, describes a presentation layer (OSI  
layer 6).  The spec does not directly address layer 3 issues.

Among possible topics would be:

addressing - unicast, multicast, and broadcast addressing schemes, SSIDs

routers - define requirements and behavior of OpenTrac routers

interfacing to various layer 2 networks - AX.25, OpenTrac UDP/IP*,  
and APRS-IS over TCP/IP come immediately to mind.  this would include  
address mapping/resolution issues.  (* yes, I know UDP is IP layer 4)

gateways - how to properly gateway OT packets to other networks such  
as APRS-RF, APRS-IS, and vice-versa

"QoS" - address data loss/FEC at a higher layer.


If you are interested in such a discussion, please subscribe to the  
opentrac-spec list:
