SDN 101: An Introduction to Software Defined Networking
Discover the advantages of SDN.
SDN has quickly become one of the hottest trends in IT. But not all SDN solutions offer real software-defined functionality. As more enterprises consider SDN, they want to know, “What is SDN? And what are the real benefits?” If you're ready to explore the advantages of SDN, and want to know how it should be implemented within your enterprise, start by reading our introductory white paper.

What I would like to do is set up an IPSec tunnel which connects over the Internet using multiple interfaces. Allow me to explain.
I currently manage two networks: 10.1.x.x and 10.2.x.x. Gateway-A (10.1.1.1) has an IPSec tunnel configured to talk to Gateway-B (10.2.1.1), making one big happy VPN. (For example, 10.1.8.8 can communicate with 10.2.9.9, despite the fact that they're on opposite sides of the Internet).
The problem is that Gateway-A has two connections to the Internet which are connected to T-1 links provided by different carriers. Gateway-B, on the other hand, connects via an OC-48. Since the VPN can only use one of Gateway-A's interfaces, my bandwidth across the tunnel is limited to the speed of a single T-1, even though I have two.
I would like to configure these two endpoints to use both of Gateway-A's Internet uplinks for their IPSec VPN. I'm using the KAME tools for my VPN setup with 2.6.11. I imagine the solution would involve something interesting like multiple routing tables, packet mangling, or hacking the IPSec kernel module. But if there's a simple solution, I'd love to hear it.
