The present invention provides a method and apparatus for facilitating communication
with non-fault tolerant network nodes in a fault-tolerant network environment.
In various embodiments, a network address or network location of any network nodes
present on a network that are not fault-tolerant is determined and stored, and
data intended for the detected non-fault-tolerant network nodes is routed only
over that network to which the non-fault-tolerant network node is connected. In
further embodiments, the fault-tolerant network comprises a primary and redundant
network with fault tolerant network nodes that are attached to each network; a
non-fault-tolerant network node that is attached to either the primary or redundant
network is then operable to communicate with any fault-tolerant network node via
data sent over only the network to which the non-fault-tolerant network node is connected.
