摘要

A control system is provided for a network system having a plurality of redundant elements wherein each redundant element has an active state and a standby state. The control system comprises a peer-to-peer-like control system that is operative to select the active and standby states of the redundant elements and a central controller system that is operative to send messages to the peer-to-peer-like control system wherein the messages allow the central controller system to override the selection of states for the redundant made by the peer-to-peer-like control system.
