Overlay Networks

What is it?Overlay Networks provide a

method for “creating” virtual domains

Enable large scale multi-tenant isolation

The Challenge:Software implementation leads

to performance degradationCPU overhead increases

Less virtual machines can be supported

Protocols:VXLAN – VMware and Linux

NVGRE – Windows
