Dear All

I have been trying Gargoyle QoS on RS Pro, but it seems it shows NO EFFECTS?!!!.

1. My network is very simple:
GW (Mikrotik BWtest server, IP 10.50.0.42) - switch - AP (gargoyle, 10.50.0.56)- STA (WDS bridge, IP 10.50.0.55) - PC (BWtest client, IP: 10.50.0.102)
All are Fast Ethernet 100Mbps, test on my table, so no issue of SNR, interference.
I use Gargoyle 1.4.7 for testing.
2. I set QOS for STA (10.50.0.55), set VoIP with: source IP 10.50.0.102 (PC), packet size: max packet length 120 bytes.

I use 2 streams BW test: one is 64 bytes TCP BW test, another is 1500 bytes UDP (or TCP) packets from PC (10.50.0.102) to GW (10.50.0.42).'

I EXPECTED that due to VoIP QoS set limitation source 10.50.0.102, packet size < 120 bytes, the BW test for 64 bytes TCP stream should be stable, but in fact the performance is not stable.

I have tried all scenarios (e.g. order of VoIP, percentage bandwidth, minimum bandwidth, max BW, ACC) on both download and upload pages, but it seems the bandwidth for 64 bytes packets are very unstable, can drop very low (< 100 kbps) .

This is BTtest for 65 bytes stream (which show unstable):
This is BTtest for 1500 bytes stream:

4. To get qos_garogoyle in /etc/init.d and /etc/hotplug/iface working, I have changed wan ->lan, but the result still showing the VoIP BW for 64 bytes packets are unstable when there is another concurent (e.g UDP 1500 bytes packets) stream.

Can anyone make similar test and check whether the BW should be unstable when there is another concurent stream, no matter QoS is set ?

I have not tried to test for latest version of Gargoyle (1.5.8), but from the source code comparision, I suppose to be the same problem.

Thanks a lot in advance

I have installed the latest version (1.5.8) and as expected, the QoS seems not working, at least to bandwidth test.

I do not have other boards to test, but I believe in case the other boars, the results are still the same: the QoS seems not working, at least to bandwidth test.

Anyone can check by setting up simple scenario:
- GW-Gargoyle AP - Gargoyle Station - PC (use fast ethernet)
- Bandwidth test from PC to GW
- Use simple graphic BW test
- In QoS on Gargoyle Station, set VoIP, source IP is IP address of PC, Destination is IP address of GW, set max packet size is for example 120 bytes, min bandwidth for example 1000 kbps.
- Run BW test on PC with TCP (or UDP) packet, packet size 64 bytes
- Run another BW test on PC with UDP packet, packet size 1500 bytes
- If QoS works, then it is expected that BW test for 64 bytes packet flow should maintain high than min QoS bandwidth (1000 kbps)
- But the result shows that the the bandwidth for 64 bytes packet flow is unstable and can reduce to less 100kbps.

-> Conclusion: QoS seems not working of no effective

Thanks in advance
