Overlay
Network
s
In order to better scale their networks, datacenter operators often create overlay networks that
carry traffic from individual virtual machines over logical tunnels in encapsulated formats such
as NVGRE and VXLAN. While this solves network scalability issues, it hides the TCP packet from
the hardware offloading engines, placing higher loads on the host CPU. ConnectX-6 effectively
addresses this by providing advanced NVGRE and VXLAN hardware offloading engines that
encapsulate and de-capsulate the overlay protocol.
