A method of duplicating protocol for making identical the order of reception and contents of packets on the two computers of a duplicated computer system with respect to packets of specific types of communication. On the first computer, each packet taken in is checked to determine whether the packet is a packet of the specific types of communication before protocol processing. If the packet is a packet of the specific types of communication, the packet is passed to the protocol processing process and added to a virtual queue created in its shared memory. On the second computer, each packet taken in is checked to determine whether the packet is a packet of the specific types of communication before protocol processing. If the packet is a packet of the specific types of communication, the packet is discarded, and the one at the head of the virtual queue in its shared memory is passed to the protocol processing process.
Protocol duplicating configuration for making identical the order of reception and contents of packets on first and second computers which are connected to a network, have shared memories forming the same address space, and make up a duplicated computer system for packets of specific types of communication, characterized by having the following means on each of the first and second computers:
