The data plane operations are offloaded to an Embedded Switch (E-Switch) in ConnectX-5 while allowing the SDN control plane operating on the host CPU to remain unmodified. Instead of replacing the TCP stack with a TOE entirely, there are alternative techniques to offload some operations in co-operation with the operating system's TCP stack. TCP checksum offload and large segment offload are supported by the majority of today's Ethernet NICs. Newer techniques like large receive offload and TCP acknowledgment offload are already implemented in some high-end Ethernet hardware, but are effective even when implemented purely in software.
