Receive-hashing
Webb15 mars 2024 · A NIC uses a hashing function to compute a hash value over a defined area (hash type) within the received network data. The defined area can be noncontiguous. A number of least significant bits (LSBs) of the hash value are used to index an indirection table. The values in the indirection table are used to assign the received data to a CPU. Webb11 mars 2024 · Hashing, in short, consists of a mechanism to translate a given variable-length sequence of bytes into another byte sequence with a fixed length. So, we can call the hashing result (the fixed-length byte sequence) of hashes, hash codes, or digest.
