Abstract

One embodiment in accordance with the invention is a method that includes detecting a failure in a ring network and transmitting a multicast message across the ring network that includes information regarding the failure. Additionally, a new ring master of the ring network is designated. Furthermore, a ring port coupled to the failure is blocked.
