Abstract
OFMP is a hierarchical, network management pro­
tocol that enables group operations to be executed on
the management information bases of all nodes in the
group. As long as no faults occur, OFMP ensures that
all nodes execute their local operation exactly once
in each group operation. If ``immediately­detectable''
faults occur, it ensures masking fault­tolerance; i.e., all
non­failed nodes execute their local operation exactly
once in each group operation. And, if ``eventually­
detectable'' faults occur, it ensures stabilizing fault­
tolerance; i.e., it eventually converges to a state from
where all non­failed nodes execute their local opera­
tion exactly once in each subsequent group operation.
Of special note is the ability of OFMP to detect us­
