Dear gentlemen,
I want to raise you a technical doubt that I have with your XXXXXX product. I explain you one situation.
For example, I have:
- Two ADSL links of different ISPs that both are connected to Internet. Those ADSL links have 20Mbps of downloads band width. Both links are connected to a XXXXXX device.
- One PC in the LAN.
- One file with a size of 100Mb allocated in a server in Internet.
The doubt is:
If I download this file from the PC It will be downloaded with a bandwidth of 40Mbps or at a bandwidth of 20Mbps?
In other words, the traffic of the download is directed (balanced) by one of the two links (20Mbps) or it's directed by the two links (20Mbps+20Mbps = 40Mbps).

For those types of traffic to be bonded, you will need a peering node, either at a data center, or as a service from us (Broadband Bonding Service), as it is technically impossible with them for non-http traffic.
Please let me know if you need additional information or if you have any questions.

Cahit, very thanks by your answer.
Let me another question, please: Why only with http downloads and not with ftp or another traffics?
Best regards,
Ramses

Asunto: Re: Technical doubt about Truffle device (Broadband Bonding Network Appliance).
Hello Ramses,
Short answer is 40Mbps for http downloads.
Our devices have 2 operational modes.
1) Standalone mode: In this mode, our Truffle appliances will bond all http downlink traffic. As an example if you were to download a file behind the Truffle device which has 4 ADSL lines plugged in with 6Mbps speed each. Your download speed would be around 24Mbps even for that single file download. For all other traffic, our device will implement the "intelligent load-balancing" where the Truffle device will distribute the different Internet sessions, on various WAN links on a session by session basis. Truffle will keep the application semantics in tact, by making sure the sessions from certain applications are kept on the same WAN line, such as banking sites, where a blind load-balancing would break the application.
2) Peered mode: When Truffle is peered with another Truffle device with a VLL server license over the Internet (let's say a branch office and a headquarter office), the two units create a virtual leased line connection between them over the bonded pipe. In this mode downlink and uplink is bonded for all types of Internet traffic.
Peered mode can also be achieved by our monthly subscription service: Broadband Bonding Service (BBS). BBS is optional and let's the customer Truffle device peer with one of our data centers to enable bonding for all protocols. As I mentioned, BBS is an optional add-on service.
I am attaching the brochure for Truffle and Truffle Lite. In case your project involves more than one office, here is a link for a white-paper about our usual ISP and multi-office installations.
We have a remote online demo through a gotomeeting session, where we showcase a real Truffle unit in action and fly through some of the features within 15 minutes. As a next step, would you like to schedule that?
Warmest regards,
-jay

Ah, eso está muy bien.

Este fabricante dice que hace falta un concentrador en las instalaciones del ISP (entiendo) además de necesitar colaboración por su parte y que en España no tienen ningún acuerdo con socios españoles, por lo que este dispositivo quedaría descartado (la idea es unir el ancho de banda de dos conexiones de banda ancha a través de un dispositivo autónomo).

Aquí también me faltan datos... ¿sólo te ha respondido eso? :-?

Any http traffic, the technology decides the best way to perform the download bonding.

Daren, very thanks by your answer.
You want tell me that if I only put a LINKaXcel appliance and I connect it two ADSL links of 20Mbps, I can to download from Internet, for example, via ftp, a file of 100Mb of size at a bandwidth of 40Mbps (20Mbps+20Mbps)?
Who decide what part of the file need go across a link and what part to the other link?

Ramses,
With the proper appliance, yes you can download at 40Mbps based on your question.
Our link bonding, actually bonds the links together for faster download throughput, we have unique technology that does this.
It would require our LINKaXcel appliance to accomplish this task, see the attached.

Subject: Technical doubt about Edge2WAN device.
Dear gentlemen,
I want to raise you a technical doubt that I have with your Edge2WAN product. I explain you one situation.
For example, I have:
- Two ADSL links of different ISPs that both are connected to Internet. Those ADSL links have 20Mbps of downloads band width. Both links are connected to a Edge2WAN device.
- One PC in the LAN.
- One file with a size of 100Mb allocated in a server in Internet.
The doubt is:
If I download this file from the PC It will be downloaded with a bandwidth of 40Mbps or at a bandwidth of 20Mbps?

------------------------------------------------------------------------------------------------------------------------------------------------------------------------
- Como ves, ellos te dicen al principio que sí, que a 40Mbps, pero si los obligas a ceñirse a la situación planteada, que es si realmente se suman o no, es decir, si desde un único punto (PC) puedes utilizar todo el Ancho de Banda para descargar un único fichero (que sería la situación real de que se suman los Anchos de Banda), ya empiezan a salir "peros" y situaciones concretas en las que únicamente se podría. Y si sigues apretando, pues aparecerá la situación única en que lo pueden conseguir...
- Vamos, este último, hasta dice al principio que su tecnología es la única que lo hace. Después le afinas, y ya es que solo lo hacen con http...

El dispositivo de Teoip sí necesitaría colaboración del carrier (al menos es lo que se desprende de la respuesta) pero de los otros dos no me queda claro tras haber leído esas respuestas que has enviado.
- Todos necesitarían montar algo en el Carrier, si es para acceso a Internet, o si es Peer to Peer, montarlo en la oficina remota.

Eso te lo has sacado de la manga ya que no lo dicen por ningún lado (ni si quiera el aparatejo de Teloip) ;-)
- Que va, de la manga no, si hasta lo dicen ellos cuando les dices que no se vayan por los "Cerros de Úbeda", que ciñan la respuesta a la pregunta. Y es cuando ellos te dicen:
"For all other traffic, our device will implement the "intelligent load-balancing" where the Truffle device will distribute the different Internet sessions, on various WAN links on a session by session basis."
En definitiva, y que no me lo saco de la manga, que si hacen Load Balancing, si se les cae una de las WAN, siguen mandando el tráfico por el resto de los enlaces WAN que tenga conectado el dispositivo, por lo que aumentan la Tolerancia a Fallos.
¿Sabes por qué podías sumar los canales de una RDSI (64+64 = 128Kbps?. Porque era el mismo enlace físico y lo controlaba el proveedor también en el otro extremo...
Lo que estamos comentando aquí sería como una RDSI de cada Operador, por ejemplo 2 RDSI, y sumar los 4 canales para tener 256Kbps. ¿Piensas que se podría...?
Esta es una solución fantástica para "sumar" el Ancho de Banda de varias ADSL's / Enlaces WAN.

OJO, no la he probado, pero hay gente que dice que va bien...
