Give packages thats less then 64byte higher priority.

Hi guys!

I was thinking about the hole problem where the upload-speed slows down the upload and vice vera. So I gooled a bit and asked around on forum's, I found out that it was becuase of the ACK-packages was que'ed, and the best solution was to give packages thats less then 64byte higher priority. And I guess this is the place to ask, if it's possible to give the acknowledgement packages (or packgades less then 64byte) higher priority within Direct Connect? Many of it's users have DSL and similar connections where the bandwidth isn't split equally, so it's a pretty large problem. Sure it might also be becuase of the non full duplex, but the queing of the ack-packages have to do very much to.

Sorry for the formulation and spelling

I don't think DC++ should be mucking around in the TCP/IP stack. It's much lower level than it should have to deal with.

So it's not possible to just change it within dc?

In short, no.

Patches are welcome.

There's an RFE in the old tracker for using the QoS flags for some packets, which is also low level, and my have success as well.

As far as I'm concerned, that would be an expansion of what PseudonympH said. But that's just my opinion (and apparently his as well). Others may have different thoughts.

This is afaik not possible to do in any portable way, and doing it requires very low-level stuff as already said. The best bet is actually to run WonderShaper or something like that on a linux router instead.
