I finished off 2014 with a round of predictions about the future of network virtualization, and now I find myself preparing my VMworld® 2015 session on a similar topic. So as a preview of what I’ll be talking about in a few days (and later on at VMworld Europe), I thought it would be worth looking […]

Before I launch into some predictions for 2015, I want to take a quick look back at the post I wrote a year ago, predicting how the network virtualization landscape would shape up in 2014. This is not just to pat myself on the back for getting a few things right (my predictions weren’t that bold […]

For as long as we’ve been doing Network Virtualization, there has been debate about how best to encapsulate the data. As we pointed out in an earlier post, it’s entirely reasonable for multiple encapsulations (e.g. VXLAN and STT) to co-exist in a single network. With the recent publication of “Geneve”, a new proposed encapsulation co-authored […]

As 2013 comes to a close, it’s time to pull out the crystal ball and make some predictions about 2014—specifically, about what we’re likely to see in the Network Virtualization space in the coming year. The safest prediction I can make is that Network Virtualization will see a significant uptick in adoption next year. That’s […]

Network virtualization, as others have noted, is now well past the hype stage and in serious production deployments. One factor that has facilitated the adoption of network virtualization is the ease with which it can be incrementally deployed. In a typical data center, the necessary infrastructure is already in place. Servers are interconnected by a […]

[This post is a joint effort by Brad Hedlund, Scott Lowe, T. Sridhar, Martin Casado, and Bruce Davie] Without a doubt these are transformative times in networking. Everything we’ve known about how to build and operate networks over the last quarter century is changing: networks are evolving from interconnections of individually configured devices to software-defined, […]

[This post was written by Bruce Davie, Martin Casado and Brad Hedlund.] Some months ago, we wrote a post over on Network Heresy explaining the relationship between various tunneling protocols that are used in support of network virtualization. Because this issue of the encapsulation used for network virtualization seems to keep on causing confusion, we’re […]
