Abstract
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, 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.
