If you don't know what this is, it is called a Load Balance Broadband Router. It comes with more than one wan port, and the wan port is where you plug in the modem to the router. A typical router has just one wan port where you plug in your cable or dsl
modem to. A small or medium sized business may require more than one modem to get the bandwidth it needs. They may have 2 to 4 modems, so they can use a device like this to boast their bandwidth across their network. There are other methods of doing this, but it is more complicated. This is the easiest way to do it.
It is very similar to how RAID works for hard drives. RAID allows you to combine the transfer speed, and storage capacity of two or more hard drives. For example, if you had two 4 tb hard drives, you could combine it to one hard drive of 8 tbs which would also make it faster than a single hard drive. The problem with the RAID configuration is if one of the drives fail, what was saved in it is corrupted. With a Load Balance Broadband Router, if one modem or connection fails, the other modem or modems will still provide bandwidth. Let's say your network has 3 modems with a combined bandwidth of 100 Mbps, and one of the modems fail. Each modem has about 33.3 Mbps, so your network will still have 66.6 Mbps in bandwidth.
If you have broadband internet at your home, you probably don't need two broadband modems from different ISPs. One is going to be enough for most people. If you have a business where the internet can't be down for whatever reason, this is a good solution for that problem.
