Network competitive prevention device and network competitive prevention method

摘要

A resiliency-link having a master node and slave nodes may be used to automatically avoid network conflicts due to failure of a node stack. Any stack stub formed as a result of the failure of a stack node or link may use the resiliency-link to determine whether the stack Master node is still online and providing service. If communication over the resiliency-link determines that the original Master node is offline, a new stack stub takes over and provides the desired service. If the original Master node is still online, then the new stack stub takes an appropriate alternative or fallback action.
