I've been using the dd-wrt firmware on my router and I like it a lot!
But -- I'm not sure the quality of service (QoS) is working on it. I have it set up as follows:
- http, port 80 -- Premium
- bittorrent, port 6969 -- Bulk
- https, port 443 -- Premium
- dns, port 53 -- Premium
Per the QoS documentation, these levels are:
bandwidth is allocated based on the following percentages of uplink and downlink values for each class:
- Exempt: 100mbps - ignores global limits.
- Premium: 75% - 100%
- Express: 15% - 100%
- Standard: 10% - 100%
- Bulk: 1.5% - 100%
This doesn't entirely seem to work, though -- with busy torrents going I get major pauses in my web browsing which sucks!
The QoS documentation gives some steps to check the QoS ...
What you'll be interested to look at will be the first set of source and destination IP, including the port numbers. Next the presence of l7proto and the "mark" field. The entries indicate the current live connection QoS priority applied on them based on the "mark" field. The "mark" values correspond to the following
- Exempt: 100
- Premium: 10
- Express: 20
- Standard: 30
- Bulk: 40
- (no QoS matched): 0
You may see "mark=0" for some l7proto service even though they are in configured in the list of QoS rules. This may mean that the layer 7 pattern matching system didn't match a new or changed header for that protocol. Custom service on port matches will usually take care of these.
On port 6969 (bittorrent) I see a weird mixture of stuff with
mark=40 like so

I've been playing around with this log for a little while and I can't see any patterns!
Why is some port 6969 bittorrent traffic tagged
mark=0 (not matched) by dd-wrt's QoS while others are tagged
mark=40 (Bulk) .. any ideas?
