Address Refresh Method and System

This invention describes refreshing address-forwarding lists when a link switches between fault and recovery states. The node connected to the affected link refreshes its list, sets a PF flag to suspend refresh operations on its other ports, and sends address-refresh information to other nodes. Receiving ports refresh their lists only when the message’s identifier differs from the identifier stored at the port and the PF flag is not set. The approach uses the flag and identifier comparison to determine whether a refresh should occur.

Method and a System for Preventing a Network Storm from Presenting in a Multi-Ring Ethernet

This invention aims to prevent network storms by limiting the response to a link failure: at most one ring-protection link in the same logical area as the failed link is unblocked. In one arrangement, each link belongs to a single logical area, whose master node unblocks the protection link. In another, links may belong to multiple logical areas, each assigned a priority; the master node for the highest-priority area containing the failed link unblocks its protection link.
