Abstract
Packet processing apparatus includes a first interface coupled to a host processor and a second interface configured to transmit and receive data packets to and from a packet communication network. A memory holds context information with respect to one or more flows of the data packets conveyed between the host processor and the network in accordance with a reliable transport protocol and with respect to encoding, in accordance with a session-layer protocol, of data records that are conveyed in the payloads of the data packets in the one or more flows. Processing circuitry, coupled between the first and second interfaces, transmits and receives the data packets and includes acceleration logic, which encodes and decodes the data records in accordance with the session-layer protocol using the context information while updating the context information in accordance with the serial numbers and the data records of the transmitted data packets.
