Windows 7: load balancing

For mission essential applications, T1 and T3 are the way to go.
Generally speaking, datacenters use the T1/T3/DS3/OC12's because they get full bandwidth in both directions and SLA'S (service level agreements) from the providers.

Generally speaking, just because it's a T1/T3 doesn't mean it will have lower pings....and cable models/DSL should NOT be seeing packet loss. I've been on a 2 way cable modem for about 12 years now and when I experience packet's a call to the ISP to get it fixed.

With the exception of nice upload...I don't think hardly any home user would be happy with a T1 over a cable modem that provides 10+mbps bandwidth.

Another note...
Windows 7 will in fact use to two separate WAN connections. It doesn't, however, do any active load balancing (as far as i can tell). I think it routes traffic through one connection or the other based on the IP it's connecting to. For example, if I visit, it will always show the same IP address. But if i go to a different site like, it will display my other IP.

Also, online bandwidth tests will not show the results of load balancing. When you start a test, it establishes a connection with only one of your internet connections, and uses that for the entire test. To truly see the result of load balancing WAN's, you have to use something like Bittorrent, which establishes hundreds of connections. This will allow your load balancing setup to distribute the connections between your two internet connections.
Finally... Whether you want to set up active load balancing with a VM, or simply let windows manage the two connections, you will need to make sure each connection is on a different subnet. So if you have two routers, configure one to operate on 192.168.1.XXX and the other 192.168.0.XXX. Configure both NIC's manually. If you rely on DHCP, they will both connect to the same network.

I'm also looking for a solution on how to load balance several connection. Only problem is that my setup is somehow unique to the look of it.
I got one Fiber connection 20/20Mbit. But it runs with PPPOE. Even to start with this, its really rare for such connection. Now on the top of it. I can call out as many PPPOE sessions I like but only to a total speed of 100/100MBit. 20Mbit x 5 if I want to stretch out the usefulness. However I can call out even more sessions but the combined speed can never go over 100Mbit for what its worth. I just 1 NIC thats why I cant do any specified NIC routing per app. Well I could use routers, but then I had to use 4-5 routers for each connection so gonna stay away from that options.

I could never figure out PFSnese and Vmware routing either.

Anyway. Right now I'm simple using some PS2 script to call out pppoe sessions. The script find out my newly assigned IP addresses automatically and binds/routes to specified IP address. This is extremely useful when downloading from Newsgrups which allow more IPs to be connected at the same time. Getting speeds of about 10500kB/s maximum here.
It does work with local country torrenting also when I bind specific ISPs to a selected PPPOE connection. Ofcourse I can not do this worldwide so here is where it stops with torrenting.
For worldwide torrenting I use Vmware and 3 Virtual XP machines.

Network Load Balance Script

Meni's Blog: Network load balancing using Windows 7

A small Vscript for Network Balance. I have tried and it's pretty cool.
You may need to do little modifications to adjust according to your needs.
The video explains the basic principle.

Have Fun :)
