I understand that checksum calculation at the sender side is often offloaded to the NIC. Does this also happen for verification at the receiving end?

1 Answer 1


There are some NICs that perform offloading, if configured to do so by the OS and drivers. This is not universal, and it can cause problems.

Host configurations and applications are off-topic here, but you can search for tcp offloading on Server Fault and Super User to learn about the problems you may encounter, and how to disable the feature if necessary.
