search for: 400kbit

I''m streaming audio over a WAN that is 1.5Mbit/s. The audio has to go both ways and can be over tcp or udp. The manufacturers recommend udp as it has less overhead but has a higher chance of dropping out. The audio requires 130-200kbit/s in each direction for a combined 260-400kbit/s. I have two transparent bridges on either side of the WAN to do traffic control. I split it so that each bridge is capped at half of the total bandwidth allowed with some leeway for performance since most network traffic is one-sided in the exchange. ie: client at co-lo makes http request...

Hi all, First of all, I have spent a lot of time reading up on it. Anyway, I live in a shared accomodation with 2 roommates and a landlord and we share a cable internet connection. It is 2Mbit/400Kbit connection. Sometimes when one of us is downloading a song through Kazaa or a new Linux or FreeBSD iso, the bandwidth gets hogged and other users can't get through. I was trying to configure dummynet using Fair Queues but I seem to be missing something. I tried to modify some of the examples o...

...ol ip parent 1:0 prio 0 u32 match ip dport 22 0xffff flowid 1:11 When this script is applied across eth0 (when I do a sftp to another machine) the bandwidth limitation is applied correctly. However if I use this in loopback (sftp to another directory in the same machine) then I get bit rate approx 400kbit - i.e. usually it roughly multiplies the bit rate by 8. Why does this happen? Does HTB work differently in loopback? Any clue regarding this would be mostl helpful. Thanks Kiruthika

...piece-wise linear service curve. My goal is to separate audio streams from bulk traffic. To keep it simple a use two classes one high priority realtime and the other for the rest.

It shortens the ti...

...n busy if this number is reached. We have PBX Trunks registering to the Asterisk. So we want to limit the number of concurrent calls to a PBX and return busy, if more than the configured number of channels are in use. I set for example: device_state_busy_at=4 to limit the trunk to 4 channels so 400kbit/s can be assured by QOS measure. But when testing, I noticed caller don't get busy. pjsip show endpoints happily shows 5 of 4 channels in use. Do I have to query the device state from the dialplan and manually return busy?

...lem sharing DSL upstream bandwidth with users. I have 3 types of traffic high-priority, medium-priority and low priority. My upstream rate is 960kbits. Traffic (any priority) can vary in bandwidth from 0 to 960kbits. I have a test setup where I can pump 600kbit of high priority sustained and I have 400kbit of low priority traffic sustained. I expect after the 600kbit high-priority traffic, the remaining 360kbit should be allocated to the medium and low priority. Since I do not have medium-priority everything should go to low-priority traffic. However, I do not see that behavior with the following tc...

...0% = 900Kbit. 3) I stop download B. A goes up to 1Mbit. 4) I apply a client-side limit to A''s download. Now A goes to 600Kbit. 5) I start downloading B again. B cannot steal any bandwidth to A, but it will get all the available bandwidth. So A will stay at 600Kbit, and B will go at 400Kbit. I hope my explanation is clear. Wondershaper does not seem to do this. In fact, when I start downloading A and B, they seem to equally distribute the available bandwidth (I verified that packets really go to the respective classes, so it''s not a filter problem). It''s not cle...
