Abstract:
A system for hardware offloading programs a network interface card with a mapping between (i) a connection identification (CID) for one or more Quick User Datagram Protocol Internet Connections (QUIC) data packets and (ii) a symmetric key and a crypto algorithm. When one or more data packets are received over a network, the one or more data packets are parsed to identify the one or more data packets as QUIC data packets and then obtain the CID for the QUIC data packets. The CID is sent to the network interface card that identifies the symmetric key and the crypto algorithm based on the CID to perform a crypto decrypt operation on the QUIC data packets, and reassembles the QUIC data packets, and an encrypt and large send offload (LSO) on transmit. A software control complexity and processing burden is thereby reduced.
