SELECTIVE HOST INTERRUPTING METHOD OF COMMUNICATION EQUIPMENT

摘要

PURPOSE: A selective host interrupting method of communication equipment is provided to remove interrupts with big burden but in idle state to thereby enhance an overall communication performance by generating an interrupt according to the intention of the transmitting party when a packet bigger than a maximum transmission unit of a network card is transmitted and received. CONSTITUTION: A transmitter processor segments a packet desired to be sent to bit an MTU of a network card and stores the information(402) in a place to which a control program of the network card can approach. The control program of the network card reads the packet information and generates a header(401) for each packet. At this time, a flag is inserted only to a header of the last packet to generated an interrupt and transmits it. When a receiving party receives the packet, a control program of a network card of the receiving party judges whether it generates an interrupt with the packet header, and makes a direct memory access of the packet to a user processor of the receiving party.
