(reat in the CT Magazine) They plan to implement (as it was possible by ISDN) channel bundled ADSL Lines.

Hi Indunil ok, but (not shure) you have only one ADSL Line right? I think the solution is ment for backup porpouses, which means: if the main ADSL Line fails all traffic will be routed to the ISDN Backup Line In Switzerland the ADSL System is normally built like this: ENDUSER has a ADSL Router/Modem -- calls via DSLAM Port on the POP of the telefony carrier (Swisscom) -- and if all is ok, the traffic will be routed to the Endpoint Normally (as far as i know) swisscom uses Concentrators after the DSLAM Ports on the telefone centrals, to put some groups of users (Districts) together to one paket and then routes the hole stuff to the Internet. And also an ADSL Line (Signal) will be bound to one telefon number, which means, you can have only one signal on one telefone wire (dosen't matter if you have analogue oder ISDN Connection) regards E.Altherr Yes, just set up a load-balanced default route in your OS, and policy routing to route already connected traffic out via the correct ISP.

[squid-users] Re:[squid-users] Re:Re: [squid-users] How to setup two ADSL line on a single linux box?
Note this remark What this will not do: This type of spanning will not aggregate bandwidth for a single user. By this I mean that if you have two 5 meg DSLs you won't magically have a single 10 meg connection. This is because it routes destination IPs via one of the two ISP connections, so if you're downloading a single file from freshmeat.com all requests for freshmeat.com will go in and out one of the two interfaces (until the kernel's routing cache expires). It will not try to open two connections to the IP using both lines at the same time. as i described below: it's not possible (at the moment) to open 2 ADSL Ports on the same telefony wire... so if you have 2 5 MB Lines you will have still 2 5MB Lines after implementing this solution more not) If the Line is open (on the DSLAM which is managed by the telefony carrier, you have normally one port configured for ADSL) So its a illusion to think, that you can do this regards E.Altherr Hi Indunil ok, but (not shure) you have only one ADSL Line right?

Hm, but with my method described it won't work so... If you have 2 ADSL Lines (let's say 5 MBit each ) ) after load balacing the bandwidth woud be the same. the only goal is failover for the lines more not. Much ADSL Carriers (like Swisscom in Switzerland) limit the bandwith so you can't go over the limit, or ADSL won't work For this case VDSL is (on my oppion) the better solution, the only requirement for VDSL is a new Router/Modem on the client side, which can handle the higher speed level and of course for VDSL the wires must be excellent quality with no distortion, or otherwise VDSL won't work On Wed, 12 Sep 2007 11:34:52 +0200 (MEST) [EMAIL PROTECTED] wrote: as i described below: it's not possible (at the moment) to open 2 ADSL Ports on the same telefony wire... so if you have 2 5 MB Lines you will have still 2 5MB Lines after implementing this solution more not) If the Line is open (on the DSLAM which is managed by the telefony carrier, you have normally one port configured for ADSL) So its a illusion to think, that you can do this The OP did refer to two adsl lines.

Something to remeber: Most Providers do traffic shaping, which means, more than the limit isn't possible and the rest will be cutted! in the past i had a ADSL and Cable Line and for testing porpouses i tried load balancing, but the speed was'nt doubled (5 MB + 5MB), i reached a maximum of 7 MBits instead of 10MBits Reason: Cable is a star topology network and therefore if much users are online there on the same headend the speed will be dramatically reduced, while this doesn't affect ADSL (which is normally separated) However: after changing completely to Cable 10Mbit everything worked fine and my ADSL was obsolete. regards E.Altherr Sorry wrong, you're right, but works only with two different lines (ADSL and Cable p.a) but not with ADSL,cause this tecnology is a sinlge line solution in my earlier posts there was a statement about channel bundeling for ADSL (linke ISDN) and this woud increase the bandwith disscused in germany http://www.gatworks.de/ADSL_Kanalbuendelung.191.0.html (sorry only german) regards E.Altherr Not shure, if it works so, will say: if you have two lines and do alternate routing on both lines (any experinces by other users??)

Lucky you are Well here in Switzerland the Cable Network is built by Cablecom, and there network is often very lousy quality and slow -- especially while the rush hours sometimes the effective rate (i have a 10MBit Abo) is going to 5 MBit or even less and downloads and gameservers p.a. will be timed out *** very angry *** -- in my oppion the main problem with the cablecom network resulted in Takeovers of other Telco's in the past. Traceroute are going directly to aorta.net(the main firm which holds Cablecom) and so they are spreded around the Inet over transits outside switzerland and the other stuff is, that CC packed all other medias, like Digital TV and Digital Phone on the same backbone which clearly results in a bottleneck But Cablecom has promised to upgrade their network as soon as possible (only god knows, when exactly) anyway: -Ursprüngliche Nachricht- Von: Marco Hahnen - ITSM [mailto:[EMAIL PROTECTED] Gesendet: Mittwoch, 12.

However, with two dry loops or live lines (or more) it is possible to bond the circuits together for aggregate bandwidth. That being said, the sum is not simply the bandwidth of each link * number of links. There is some bandwidth lost to the overhead of the bonding. FWIW, here is an isp in UK which does just this: http://www.upstreaminter.net/ But this is really straying from the topic of squid ;-) Chris
