RE: [Asterisk-Users] Lower cost router suitable for VOIP ?
One thing I will say is that my test environment isnt exactly huge, I'm using Asterisk with 2 x100p's (PSTN access) and voiptalk here in the UK. They offer an IAX2 trunk - PSTN gateway service. I also have a voiptalk SIP account that I test with as well. I have tried a few other adsl routers before I tried this, namely a Solwise SAR715 ADSL Router and an OEM Connexant DSL pile of filth. Neither would work at all with SIP or the IAX2 stuff. I have also had issues with iptables that I wish to never have to think about again! Since installing this Zyxel DSL router I have had pretty much no problems at all. The Bandwidth shaping is basic but consequently quite simple. It has SIP, FTP and h.323 as preconfigured profiles that require nothing more than a source and/or destination address, priority and amount of bandwidth to allocate. Other protocols require port number and protocol type as you'd expect. If configured to share root bandwidth among classes then it will happily allow browsing and leeching at full speed, but when you make a call there will be a near instant drop in download speeds elsewhere. I allocated 176kbps to port 4569 udp (IAX2) and found that using the voiptalk service was fine. I'm having a few ATM issues with our dsl here that didnt help testing earlier today, but when the dsl is behaving itself, using the voip is certainly no different to using the pstn over asterisk. Both methods are using gsm as the default codec right now. There was the occasional defect in the voice I will admit, but that just the odd bit of packet loss I think. jd -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Adam Goryachev Sent: 07 September 2004 13:13 To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: RE: [Asterisk-Users] Lower cost router suitable for VOIP ?

Linksys released a new firmware for the WRT54G with QoS included, so there should be no need for the sveasoft hack. For a cheaper solution, stuff a couple of extra ethernet cards in a PC and make it your firewall by installing smoothwall in it. There is a module that adds QoS to it and it seems to work pretty well.

Re: [Asterisk-Users] Lower cost router suitable for VOIP ?
Hi, I believe what you're looking for is QoS. I didn't mess around with it yet... But I know you can setup a cheap linux router with it, so your VoIP traffic will get more priority. Here's an idea: setup one linux box as a router, with 1 ethernet for inside voip, another one for the rest, and the last one to the outside world. I'm sure you'll find the necessary tools for linux QoS. Maybe you could have only one inside ethernet connection, and the QoS thing will let the voip traffic pass with higher priority, but I don't really know about that. The 2 inside ethernet setup sounds easier to configure... Hope it helps... Marconi. - Original Message - From: James H.

I'm sure you'll find the necessary tools for linux QoS. To ensure everyone is on the same page with QoS, the above will only satisfy a small piece of the problem, Outgoing data flows. In order to properly address any voip call, you really need to address both incoming and outgoing data flows. The incoming part of that can only be addressed by having your ISP (and their providers in many cases) also implement QoS.

Re: [Asterisk-Users] Lower cost router suitable for VOIP ?
Well.. ok... here goes the Short version, I will be adding examples and explanations to the wiki when I get off work... :-) Bear in mind this is what I do, change it to fit your situation... I'm on a cable modem which everyone knows just BLOWS for latency, also it's an external one so you can't control the buffering... but I've been able to use Linux QoS to make it near toll-quality with the occasional jitter during heavy downloading... I have 3Mbit download speed and an abysmal 256kbit upload speed... Needless to say that upload is a problem when shared between 6 machines... Everything that you do requires sending SYN/ACK packets and such which destroys upstream band... Unless you use QoS these packets will just be thrown at the interface willy-nilly with no regard for speed and time... There are 2 ways that I know of to do this and because of the topology of my network I actually use BOTH methods so I know it works very well! The first is to use the linux bridging code included in the 2.4.X and 2.6.X series kernels and the bridge-firewalling code included with the ebtables project (http://ebtables.sourceforge.net) to create a Layer-2 ethernet switch with QoS support. I use ebtables and it's packet marking target to mark packets that are received from my LAN and are destined to be bridged to my WAN interface hooked into the cable modem. Then I create QoS filters based on those marks... Using ebtables also allows you to mark packets based on their destination MAC whereas iptables does not... Bear in mind that this is a software switch not a hardware switch so it can pass packets at wire speed but some network drivers are horribly broken and slow (rtl8139, 3c90x, eepro100, etc..) and also when you open a lot of TCP sockets simultaneously it uses a lot of memory and CPU... This works beautifully and to the end users and applications it's completely transparent! The second way is to simply use IPTABLES and NAT to create a NAT router. In this scenario you're just using iptables' connection tracking code to do NAT/MASQUERADING (like in the good ol' IPCHAINS days of 2.2.x or the IPFWADM days of 2.1.x!). In this situation packet marking is done in the MANGLE table, in the FORWARDING chain... For those of you who feel brave/foolish enough to use the U32 packet matching code instead of marking the packets, that will work for the NAT router but not in the way you would expect for the bridge because it works at layer 2... If you already have a router like a LinkSys or a Dlink that doesn't support Qos, don't worry! I would suggest using the Linux bridge code and placing a linux box between your LAN and the router. That way you can implement QoS and strong firewalling based on IPTABLES to your hardware router! Again, I'm going to be posting examples of my setup on the wiki. Also I've written an init-style script for ebtables and am currently working on an ifup style script for the bridge device. That one's tricky because the bridge code doesn't pass packets for 30 seconds while it's Learning. Also the bridge device is traditionally not assigned an IP address... -Chris ___ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

I can saturate the link without breaking a sweat -- not in CPU nor memory. -A. ___ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

Re: [Asterisk-Users] Lower cost router suitable for VOIP ?
Generally speaking, the bulk of data flowing in any end-user pipe is contained in TCP and that can be rate limited on the receiving side. UDP traffic you're more or less out of luck with unless the ISP supports ECN which many do not. So really the key to VOIP on consumer grade connections simply not to fill your pipe, since you have no control over what is prioritised. That's basically what I'm doing... I'll post examples but that's about all you can do... It's really up to the ISP, but all I'm saying is that you can have a pretty decent setup without Carrier-Grade SLAs, you CAN do it over pretty much any broadband connection within reason of course... Also jitter can be a problem if the ISP is using RED... RED really falls short for UDP, it was designed with TCP's backoff algoritms in mind. RED like many other QoS schedulers works by dropping packets... this is not good for VoIP... ___ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
Re: [Asterisk-Users] Lower cost router suitable for VOIP ?
Actually to be fair I think it was more a combination of the NIC driver and the connection tracking code at the time that lead to the lockups... With connection tracking and bridging, the firewall tracks EVERY connection, not just NAT so it can use a lot of CPU/Memory... But the Intel drivers can be a bit slow and CPU-intensive, there's been lots of discussion about that... -Chris ___ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

I don't remember any eepro100 driver lock-ups, and I have at least 1000 card-years of experience with them, ranging back from 2.0.x to 2.6.x. We replaced all of our 3com cards due to driver problems (circa 1998), but the Intel cards Just Worked. We never noticed a CPU load problem, but we were only rarely concerned with CPU load, anyway.

Ok Way OT, I didn't mean to get into a religious debate, I like the Intel cards, I have several of them and recommend them to my friends, etc... Be that as it may... This was using these cards in a software bridge... significantly more traffic than an ordinary end-to-end connection... Packets destined for MANY different PCs are being passed through the card... It may have been a combination of the bridging code and the NIC drivers that lead to the instability problems I experienced... I've always been nervous about Tulip clones. I have a half-dozen 21143 boards at home that are great. The tulip cards are awesome for the simple fact that they're hella old... (yes that's the scientific reason!) The tulip design goes back to the old DEC 21040 chips of the early-mid nineties (ahhh the good ol' days!) There has been a lot of time to play with these chipsets and they are well documented so pretty much all of their functions work well and there are no surprises The problem with Intel/3Com/et. al. is that the open source drivers either have to be reverse-engineered or the company has to be open-source minded enough to share information... There are many undocumented features in these kinds of drivers that just kinda work(tm)... Again... I have no affiliation with one or the other, no religious prefrences, no nothing... This is just what I've found using the cards... YMMV! -Chris ___ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
