Abstract
In a bridged, pipelined network (FIG. 1), a network-to-host bridge ( ) identifies the address space of a host computer (FIG. 2) as not being contained within the host computer memory space ( ). During the removal of the host computer ( ) and its replacement by a new host computer, the network-to-host bridge ( ) momentarily locks out traffic (FIG. 3, step ) in order to disable peripheral components (FIG. 1, ) from initiating bus transactions. When the new host computer is installed (FIG. 3, step ) and the bus lockout is removed (step ), the new host memory area is protected from direct memory access transactions which were stored in the bus hierarchy during the host computer swap.
