Residential router w/ QoS support?
Did anybody ever come across an affordable, residential cable/dsl router with support for QoS? The ones I've seen so far (Netgear, D-Link and W-Linx) do not seem to support it. I noticed that even email can damage a G.711 stream on an 128kbit uplink, leave alone file-sharing applications. I understand this is strictly related to *, but nevertheless of interest to many of us. Thilo

Linux Qos : PRIO qdisc works
Hi, all I am interested in Linux related QoS, especially PRIO queue discipline (qdisc). I test some experiments about PRIO qdisc. Host A ------ Router A --- Router B --- Host C | 1Gbps | Host B ---------+ +-------- Host D flow 1 : Host A -> Host C (TCP) flow 2 : Host B -> Host D (UDP) priority 1 queue (pfifo, size 1000 packets ) : flow 1 priority 2

QoS in wireless networks
Hello, I''m trying to configure several wireless routers with QoS support. The idea is to implement differentiated services so that VoIP traffic gets the maximal priority, then video, control traffic, interactive data traffic and best-effort traffic. I have seen that CBQ used to be chosen as qdisc for implementing bandwith share in DiffServ but now HTB is preferred because it is

ISPs with QoS for VoIP?
I'm wondering if anyone knows of ISPs with service that has QoS features that would be good to use with VoIP stuff. Granted, the QoS would only be supported as long as you stayed within their network, but it might be better than nothing. --Eric

QoS for VoIP
As you are probably aware, this is a ever green topic. I have personally tried doing it, testing it and verifying it and I am myself finding this problem challenging and frustrating. Most of the scripts will recommend some form of rate limiting ( or policing ) on the download. But the challenge is how to determine the correct value for the policing ? Lot of the recommendation says use x %

Asterisk QOS working perfect using sveasoft 3.11g
As seen on my post at: http://www.sveasoft.com/modules/phpBB2/viewtopic.php?p=28112#28112 This works very well... It does NOT work with stable 4.0! sveasoft will be issuing a bug fix for this (4.1) in the near future. Final Rev of working script w/ asterisk support I'm not going to run alchemy on production machines until it is stablish. Remember to set your uplink properly and to set

POE Switches and QOS
3com have some goods POE kit and some very nice managed wall jacks that supply POE and are fully managed. Here's an auction that the seller just closed:- http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&category=40990&item=5708757277&rd=1&ssPageName=WDVW Last time I spoke to him he had 5 boxes of 20 units and was willing to sell them at around $575 with a bit of arm twisting.

2.6.14 - HTB/SFQ QoS broken?
Hello, First of all, I already contacted Martin Devera, the developer of HTB, and he told me to search for help on this mailinglist, thus I am describing my problems here now... I am kind of seriously annoyed by QoS as I have been trying for over 3 years to get it working properly - first I did not understand how it works, then it seemed not to work, then it was working perfectly for half a

QOS Device?
Here is the situation: A T1 router going into an office which then plugs into the firewall box then into the switch. None of these devices support QOS.. Is there some sort of box/device that I can place between the T1 router and the firewall box which will allow me to prioritize voice traffic on this link? I can't change the T1 router to something that supports QOS because it has

LAN switches with PoE? PoE phones?
Hi all, I'm looking for recommendations on ethernet switches for a new install. Ideally would want switches with at least 24 ports, ideally with a GE uplink, and that support PoE (power over ethernet) on every port. I've seen lots of switches, and lots of "power hubs", but the combination, which makes a lot of sense, seems rare. What is out there? Do the switches need to be

Was looking in to qos mainly to stop large http downloads/ftp downloads from hogging the line so that browsing for other users doesnt slow to a crawl, but if the line is free and no one is doing anything then for it to use the available bandwith.

investigate & troubleshoot speed bottleneck(s) - how?
hi guys/gals I realize that this question must have been asked before, I sroogled and found some posts on the web on how to tweak/tune gluster, however.. What I hope is that some experts and/or devel could write a bit more, maybe compose a doc on - How to investigate and trouble gluster's speed-performance bottleneck. Why I think such a thorough guide would be important? Well.. I guess
