We were a bit surprised to find out that secure, direct Internet access was the top driver. We expected other drivers, such as MPLS cost reduction, eliminating bandwidth constraints, or optimizing cloud access, to be at the top of the list. Secure, Direct Internet Access: SD-WANs Self-Made Headache?

The Internet is designed to provide multiple paths between two endpoints. Attempts to exploit multi-path opportunities are almost as old as the Internet, culminating in RFCs documenting some of the challenges. As a result, Internet devices usually use a single path and let the routers handle the path selection.

There are a number of virtual internet exchanges that BGP peer over VPN links when local presence is not available. Given the IP encapsulation overhead, and the fact that these routes still cross the public internet on the outside of the tunnel, is there a compelling benefit to BGP links over a VPN or GRE tunnel?

Latency is not a new problem in networking. Not as difficult as time travel, but it’s difficult enough so that for 30+ years IT professionals have tried to skirt the issue by adding more bandwidth between locations or by rolling out faster routers and switches. Fast forward to today, most networks enjoy five nines (99.999%) of uptime.
