2.6 Sharing - Mult. Connections or ISPs
Ok there are several cheap ways to add bandwidth to your company for under $150. Surfdoubler (www.vicomsoft.com) is a software solutions. The nexland pro800turbo www.nexland.com is a hardware solution.
To use a software solution you need 3 NICs in a server comp. 2 to connect to the dsl/cable/etc and 1 for your network.
This type of setup will be more reliable than single isp because you can use 2 different ISPs. This is not bonding, so depending on your application you may not get full bandwidth out of the dual connections. But a cable modem and DSL load balanced is a powerful setup and will keep you running when others fall short including expensive solutions with guaranteed uptime.
There are also some complex linux solutions that can be compiled into the linux kernel.
With the software you can also add additional NICs and connections as you see fit. So a person with 2 phone lines could order dsl on both and then order cable modem. The other bonus of this approach is when company XYZ goes out of business you are not out in the cold since you have 2 or more providers.
We need real links to the software. Browsing those sites is a pain.
midpoint.com is now a currency conversion site... looks like a dead link. Thanks, Matt
The is a good solution, but the best way to achieve a great throughput on a single download is to use midpoint software www.midpoint.com or surfdoubler www.vicomsoft.com along with download accelerator plus.
I stumbled upon this solution by accident actually. While using the surfdoubler software, I downloaded the windows 2000 sp2 in 1/2 the time. I looked at the software and realized to my total surprise that both connections were being used for a singe download.
How? Well it is simple. Download accelerator breaks an ftp download request into equal parts. Using the ftp resume feature it ask for each part of a file in a separate request. The surfdoubler software load balances each request over two connections. When DAP is done with the download it puts the file together as one.
But what really makes these two stand out together is the fact that DAP searches out mirror site for each part of the file. What this means, is that even if the ftp site you are downloading from is not fast enough, the mirror sites will add to the bandwidth of the total download.
For the life of me i do not understand why these two companies do not enter a partnership or merger.
Load balancing is the process of spreading out data streams across different connections. For example, say that we are on a two user network and user one is downloading an ISO. His data will go through connection one (assuming two ISP connections). When user two tries to use the internet, the load balancing router/software senses that connection one is busy and routes user two's data across the second ISP connection. In this situation, having two 1024kbps circuits does not mean that each computer has 2048kbps available to them, only 1024kbps (each computer only can use only one ISP circuit).
Circuit bonding*/muxing is a very different approach to increasing your bandwidth. Unlike load balancing, the bits of all clients are spread across all connections. So, unlike the above example, two 1024kbps circuits will equal 2048kbps (and each computer has all of that bandwidth available, unlike above). However this approach is much more expensive. Circuit bonding requires two routers and two devices called "muxs". One router and "mux" is placed at the ISP end and the other router and "mux" is placed at the customer end. You ISP must support this configuration as well, and often times providers will only do this type of connection with T1 circuits.
*Channel bonding is actually not what happens. Channels refer to a different aspect of communications.

Thanks to tarzanroute and jdepew for the list
hi, I am using a dual wan router called PePLink Balance 200. I think it's a great router that should be included in the list. Some router listed in this FAQ is no longer available. For example, Ovislink seems to be changing their product line. Thanks, Matthew
This list is getting a little dated with Xincom being (I think) out of business. I tried and failed to get support for my Xincom. I posted here WRT Draytek: http://www.dslreports.com/forum/r20862084-Router-WANLAN-Throughput-Issues-Due-to-PowerBoost You might want to consider adding them to this FAQ. They have a number of Dual WAN products and I'm very satisfied with the Draytek Vigor 2930. Thanks - appreciate the forum and the recommendation that came to me saved a lot of time.
