In order to better scale their networks, data center 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.
ConnectX-6, utilizing IBTA RDMA (Remote Data Memory Access) and RoCE (RDMA over Converged Ethernet) technology, delivers low-latency
and high-performance over Band and Ethernet networks. Leveraging data center bridging (DCB) capabilities as well as ConnectX-6 advanced
congestion control hardware mechanisms, RoCE provides efficient low-latency RDMA services over Layer 2 and Layer 3 networks.
