Hot on the heals of the VMWare/Cisco-led VXLAN announcement, an Internet draft on NVGRE (authored by Microsoft, Intel, Dell, Broadcom, and Arista, but my guess is that Microsoft is the primary driver) showed up with relatively little fanfare. You can check it out here.

In this blog post, I’ll briefly introduce NVGRE . However, I’d like to spend more time providing broader context on where these technologies fit into the virtual networking solution space. Specifically, I’ll argue that the tunneling protocol is a minor aspect of a complete solution, and we need open standards around the control and configuration interface as much as we need to standardize the wire format.
