Web Hosting Talk : Web Hosting Main Forums : Dedicated Server : QOS on LINUX ?

[prixone]

Hi,

Few time ago i was trying a solution called "VLC" to delivery real time video in wmp format but what i notice was that from time to time the client send a new request to reload the video, in other words ... it seems that the server wasnt priotitizing the VIDEO and VOICE over DATA.

I did like to know if any of you have performed a QOS installation what should i consider and how should i procced with it ?

i have 1000 Mbps port speed at SoftLayer.

Even ventrilo/teamspeak sometimes get those spikes and cute partial sound.

thanks in advance for any help

Unless there's congestion on your gigabit port, I would look more at the nice levels of your VLC processes than at QOS.

it never uses that much of resources but i will check that on the next test ...

what else would you recommend me to keep an eye at when i run the next test ?

Our transmissions usually have 5 seconds delay at max and the ms to the server is always between 30 and 200 and for those watching when the reload does not happen it is always inside those 5 seconds delay and with very good quality of the bitrate choose

You shouldn't be seeing that much variability in round-trip times to the server. I would first of all run MTR (for *nix) or pingplotter (for windows) to narrow down exactly which hop you see the latency on. If it's not on the hop directly to your server, you may not need to change anything on your end at all.

If it is on the hop directly to your server, I would check your server loads. If they are not at all high when you're seeing latency, or the latency is on another hop, you should have Softlayer investigate, submitting a copy of your mtr/pingplotter output. QOS doesn't do anything unless you have congestion, which you shouldn't be seeing with a gigabit link unless your usage is quite hight.
