RE: [asterisk-users] Load balenced (ADSL) network connections, is it possible?
Is it possible to somehow have multiple NICs in the server each with a different IP address pointing to a different default gateway (router). But then some how load balanced into a virtual network connection? Any ideas or solutions would be appreciated - just in case I have gone off at a wild tangent. I have successfully tested a MultiLink PPPoE connection with DSL tails. If your ISP supports this then that would be the best way to do it. If they can supply a 512/512 DSL connection then just aggregate these together until you have the required amount of bandwidth.

[asterisk-users] Load balenced (ADSL) network connections, is it possible?
Hi List, I need to put an Asterisk server in a remote office where only ADSL is available. Maximum of 8meg downstream 646k upstream. I need to handle 20 concurrent calls over IAX preferably uLaw, so 64k per channel.

Thanks Well, for 20 channels over trunked IAX, you will need roughly 1300Kbps up and downstream using G.711u (over 1500Kbps if not trunked). With a pair of ADSL connections, with QoS, you still don't really have anough bandwidth. Are you sure using G.729 or G.723.1 (or even G.726) wouldn't be allowed? Also, it's worth finding out if the local exchange is ADSL 2+ enabled with any operator (16Mb/1Mb). Also worth noting, that if you sign up to an 8Mbit service, and your ADSL modem manages to sync at that speed (never seen it, but it's not impossible). Your actual throughput will only be 7150Kbps (also upstream will be less than stated by the sync rate). This is before you lower these even more through use of QoS. ___ --Bandwidth and Colocation provided by Easynews.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

Now that Thomas has handled your current bandwidth limitations, I'll take a look at what you are trying to achieve... Is it possible to somehow have multiple NICs in the server each with a different IP address pointing to a different default gateway (router). With routers to handle all your routing requirements, I haven't looked at pointing my default to more than one router. However, looking at http://www.clintoneast.com/articles/multihomed.php makes it seem like it can work. Googl'ing 'linux multiple default routes' also turns up some interesting results. You might also look at running a routing protocols on the box. But then some how load balanced into a virtual network connection? Can you explain further - do you mean the single same connection coming through the single same router?

RE: [asterisk-users] Load balenced (ADSL) network connections, is it possible?
Unless my brain did melt down under the high heat here, there are a few things I would share : - 1 channel u-law uses at least 80k because of encapsulation So, think about compression - You can never use 100% of a bandwidth. (80% is a good max) - The values given are maximum values, far from the guaranteed values - Instead of adsl, I would go for sdsl (symmetrical) Where adsl is possible, sdsl is normally also possible Sdsl is more expensive but you can demand sla, higher guaranteed bandwidth (up to 50 or 100%) Never forget that the guaranteed bandwidth is between your router and the first equipment of your provider. You get NO warranty you have that bandwidth further away even on your isp backbone. Isp sales men always forget to talk about that If they say you get 100% to use all the time, sign immediately IF they put that WRITTEN alongside financial compensation if they fail. Dear mister sales man, you do not have to worry about compensation since you guaranteed it would not happen ;-) Other problems you will face with several IPs : Even if you can manage several IPs for the outgoing traffic, you cannot for incoming traffic as those are unaware of your situation Or they need to put multiple entries for you asterisk and try those sequentially Or you could go up for incoming calls and down for outgoing calls That is a simple solution, that will statistically work but NO warranty NOT really a telco way Routing problems might occur Regards, T.

Re: [asterisk-users] Load balenced (ADSL) network connections, is it possible?
Have you considered SDSL for higher bandwidth? Also, a dual wan router would help with your load balancing problem? Just google'd and spotted one that seems to be voip friendly. For incoming calls you could ask your ISP to bind your ADSL/SDSL feeds.

Re: [asterisk-users] Load balenced (ADSL) network connections, is it possible?
Have you checked out pfSense? It's based on the BSD firewall m0n0wall, supports multiple WAN links and load balancing between them. Seems like it might do the trick for you. Philip Mullis will be giving a talk regarding how to get it all setup at the next Toronto Asterisk User's Group meeting, if you're local to Toronto too.

Have you checked out pfSense? It's based on the BSD firewall m0n0wall, supports multiple WAN links and load balancing between them. Has anyone gotten this to work with Asterisk? I've got a couple of clients who've tried it but they couldn't get it to work, and I've not been given the opportunity to try it myself. -SKM ___ --Bandwidth and Colocation provided by Easynews.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
