摘要：
A method and a system for preventing a network storm from presenting in a multi-ring Ethernet, the method comprises: when a link in the multi-ring Ethernet is failed, at most one ring protecting link is unblocked, the ring protecting link and the failed link being in a same logic area. Wherein each link in the multi-ring Ethernet belongs uniquely to one logic area, when a link in the multi-ring Ethernet is failed, a master node of a logic area to which the failed link belongs unblocks a ring protecting link; or each link in the multi-ring Ethernet respectively belongs to one or more logic areas, each logic area is set with a priority, when a link in the multi-ring Ethernet is failed, the ring protecting link of one logic area which contains the failed link and has a highest priority is unblocked by the master node of the logic area.
