Abstract

A network adaptor driver includes an algorithm for determining special handling of packets by examining socket or port indications for the packets and a means for setting a special handling field in the header of outgoing packets. Specific embodiments include a table for connections that include packets without socket indications, a transmit FIFO list for determining whether a transmit FIFO is full, and a low priority receive queue. A computer readable media allowing a computer to practice the method of the invention is disclosed.
