Abstract:
This specification describes remote checksum offload for VXLAN.
Remote checksum offload is a mechanism that provides checksum offload
of transport checksums in encapsulated packets using rudimentary
offload capabilities found in most Network Interface Card (NIC)
devices. The outer UDP checksum is enabled on transmit and, with some
additional meta data, a receiver is able to deduce the checksum to be
set in an encapsulated packet. Effectively this offloads the
computation of the inner checksum which can be a significant
performance optimization. Enabling the UDP checksum has the
additional advantage that it covers more of the packet including the
IP pseudo header and virtual network identifier.
