[Commotion-discuss] QoS/packet reordering

[Adam Longwill]

Over here at PittMesh we're trying to implement something we describe as
"relative QoS" or "packet reordering" and we're not coming up with much.

Basically, we want to ensure bandwidth donors don't attach to the mesh and
then have all their bandwidth eaten up.

We have introduced a 2 router system: We deploy one Rocket outside that
broadcasts into the street and mesh it over ethernet to a wdr3600 inside
that allows people to access PittMesh from their home/business. THAT
WDR3600 is connected to the host's gateway.

Ideally, the hosts use the WDR3600 as their primary router because then we
can implement tools that should prefer Port 2-4 over port 1, the PittMesh
port.

The problem is, we haven't found a way to do this very well.

We can implement port-based QoS-- but as far as we can tell we have to
define a limit to the bandwidth-- which we don't necessarily KNOW.

What we want to do is just give priority to packets on ports 2-3. Meaning,
they get processed and moved first, regardless of any other factor. Port
1's packets have to wait until there is a break in the packets for ports
2-3.

Does anyone have any ideas on how to implement this?

Thanks
