Abstract
According to some embodiments, protocol control information is speculatively pre-fetched from an external memory unit. For example, a processing engine may speculate, based on a receive packet, a connection that will subsequently have a send packet to be processed in accordance with a protocol. The processing engine may also dynamically calculate a time when protocol control information, associated with the speculated connection, is to be pre-fetched from an external memory unit (e.g., the time may be calculated in accordance with an estimated processing time associated with the receive packet and an estimated latency time associated with pre-fetching the protocol control information from the external memory unit). The protocol control information associated with the connection may then be pre-fetched from the external memory unit in accordance with the dynamically calculated time.
