Socket tables for fast data packet transfer operations

摘要

A fast send method may be selectively implemented for certain data packets received from an application for transmission through a network interface. When the fast send method is triggered for a data packet, the application requesting transmission of the data packet may be provided a completion notice nearly immediately after the data packet is received. The fast send method may be used for data packets similar to previously-transmitted data packets for which the information in the data packet is already vetted. For example, a data packet with a similar source address, destination address, source port, destination port, application identifier, and/or activity identifier may have already been vetted. A socket table may be maintained listing previously-transmitted data packets and an instruction for handling additional data packets similar to the data packet entered in the socket table.

主权项

1. A method, comprising:
receiving, from an application, a first data packet for transmission over a network interface; identifying a similar packet in a socket table, wherein the socket table comprises information regarding previously received data packets, and wherein a similar packet is a previously received data packet in which information regarding the data packet is similar to information regarding the first data packet; and determining from the socket table, a network interface transmission method for the first data packet and queuing, when no similar packet is identified in the socket table, the first data packet for transmission according to a slow send method; and adding information corresponding to the first data packet to the socket table.
