is it possible to combine 2 networks from 2 different ISP to become one faster network?

i heared there is a device where u can plug 2 network from 2 different ISP and merge the internet to sum the speed with first ISP and second ISP..... i think the device works by dividing ur network and sending each part to the different internet provider and then combining them at the end... if this device really exists and im not lied to.... can someone tell me the name of the device? and would it work if the different ISP had different speeds?

    It gives you redundancy but not faster speed. There are several companies that can take 2 different broadband inputs and manage them, but it doesn't merge the network, it usually uses rules to round-robin the connection and when one side goes down, switches everything to the new connection.

    Here is the problem with merging. Your source ip would be different on both networks, your response packet has to get back to you! But to the outside world, that looks like 2 different requests, so the is no way the server on the far end can split the data.

    So the best thing it can do is send request 1 to ISP1, send request 2 to ISP2, send request 3 to ISP1, etc.

    (If ISP1 goes down, send everything to ISP2, so this gives you redundancy).

    This is not even ideal, because the your aren't getting the optimum route for your requests. Suppose you want to access mail on ISP1, and it sends it to ISP2, that is suboptimal.

    Now if you were an Enterprise level network, one can get BGP updates from both sides and advertise BGP updates. That way, one know the best route to a site and the site would know the best route to you, and it would change when one leg went down.

    But this takes big time planning and design.

    Such device is called Windows 2000 Workstation, to two dial-ups, aggregate together for faster network, might be updated to modern broadband connection.

    No mate, it has to be from one ISP only and is called "line bonding", which is how large business systems work, and your ISP will be happy to tell you all about it in the hope of selling it to you, safe link by the way;

    That's all there is to it really, regards, Bob UK.

    Such a device exists. But it's going to be tough installing one at the other end.

    There are "dual WAN" routers out there, but not common. Even if you find one, and install it, your fastest download speed from a single web source will be the best of the either of the two ISP speeds. You cannot "combine" different ISPs to get one higher speed. That said, some ISPs will offer "combining" with two services, but you pay a lot more for that.

    The dual WAN router provides fail-over and load balancing. That is, if two people (two computers) are on and busy at the same time, the router will assign one computer to one ISP, and the other to the second ISP. Add more systems, and the router keeps splitting the load between the two ISP services.

    Only when downloading from multiple sources (like torrents), will one computer be able to make use of both WAN links, thus increasing the torrent download speeds. But, for the most part, you only get the speed of the one ISP (the fastest) as the best speed for web browsing or downloading a single file from a single web site. Web sites cannot, by default, send the same file to two public IP addresses (two ISPs at your house) in different chunks, the web server expects to send the entire file to one and only one public IP address.
