Now that the basics are in place with regards to VXLAN and Multicast, we can move on to what needs to be done to get your physical infrastructure ready for VXLAN. The promise of VXLAN is that you do not need to “upgrade” your physical network gear for VXLAN capable gear in order to be [...]
I have fielded a number of questions on VMware’s multicast support and figure it is time I did a short blog on it. There is a good white paper on the topic on the VMware site called Multicast Performance on vSphere 5.0 that deals with performance changes that have been made to enhance multicast support [...]
Clarifications: Based on feedback I have received so far on Part 1, I need to make some clarifications to what I have covered specifically with how the protocol should be implemented.

In this blog I am going to attempt to give you a better understanding of vCDNI and how it works technically. Background: vCDNI is [...]
