I have been trying to hunt down some perceived latency issues in my network (I say perceived as when I perform pings and speed tests things look as they should, but just using the network things don’t see as quick as they should be).
In the process I have noticed that over my SXT Lite5 bridge I can “Squeeze” out other clients if I start a high bandwidth transfer.
A quick lay of the land. I have a cable modem at a remote site that is connected to a RB750r2 which then connects to a SXT Lite5 which in turn connects to the matching SXT Lite5 at my house and then into a CRS125-24G and on to the rest of my network…
[Cable Modem] ↔ [RB750r2] ↔ [SXT Lite5] <~~~~~~> [SXT Lite5] ↔ [CRS125-24G] ↔ [Rest of the network]
The SXTs are setup using NV2 and generally have a tx/rx signal strength of around -50 dBm and a tx/rx CCQ of around 96-100%
If I start up a bandwidth test from one of my CRS125’s at the house pulling data from the RB750r2 thats remote I get just shy of 100mbs (which is great). But if I start a 2nd bandwidth test on an additional CRS125 (one of them is in my house, another in my barn and they are in turn connected by 1gbs copper) pulling data from the RB750r2 (both using UDP) I see that the initial bandwidth test (lets call it remote to house) only slows down a little (say down to 70mbs) and the 2nd (lets call it remote to barn) only gets ~30mbs (even after I let things settle for a little bit))
While I don’t know if this is indeed my problem with the perceived network performance it’s something that I’d like to try and rectify. In my ideal world both bandwidth tests would end up at about an even split of ~50/50…
Essentially I’d like to queue/throttle all devices inside my network over the bridge to an even amount of bandwidth consumption.
I have been reading around and have tried a number of transparent bridge qos setups, but I must not be grasping things correctly. It seems like everything I have seen needs to classify traffic which I don’t want to do. I don’t actually care about the content of the traffic, I just want to evenly split it. I currently do this on the RB750r2 as I share a small part of my bandwidth with the owner of the remote location. I classify all traffic on his ports and queue as needed. This works fine as that port isn’t in my overall bridge. But on the SXTs both the ethernet and wlan port are part of a bridge. And I can’t seem to sort out how to apply any packet marking or queueing to a setup like that (in a generic way that just evenly splits the traffic without having to classify the contents of the traffic.)
Right now my bridge is setup with bridging fastpath and I realize I’ll need to turn that off. Not a big deal for me as the CPU on the SXTs will handle my actual external bandwidth of 50mbs downstream just fine.
Ok I am rambling here. Hopefully I have provided enough information (if I haven’t please ask for more) and somebody can shine some light on this.
Thanks in advance.
