Abstract: A computer system comprises a number of machines, each running its own operating system. The machines may be virtual machines or may be physical machines in a multiprocessor system. A first machine is a client system 10, which does not have its own network stack. Second 12 and third 14 machines are communication bridges, each of which has its own network stack 20, 22. One bridge is a master 26 and the other is a slave 28. The client sends outgoing data to the master and slave bridges. The master bridge then sends the data to a network with its stack. The network sends data to the master and slave bridges via their stacks. The master then sends the data to the client. Then master and slave exchange status information. If the slave does not receive information from the master, it becomes the master.
