Abstract
A network comprises a plurality of switches coupled in a ring topology, wherein each adjacent pair of switches in the plurality of switches forms a multiple link aggregation group interswitch connection therebetween and forms a ring resiliency protocol logical node. A first switch in a first adjacent pair of the plurality of switches is coupled via a first link to a second switch in a second adjacent pair of the plurality of switches, and a third switch in the first adjacent pair is coupled via a second link to a fourth switch in the second adjacent pair. In the event of a failure of the first link, a packet flow to be transmitted from the first switch over the first link is redirected from the first switch to the third switch for transmission over the second link to the fourth switch. However, in the event of a concurrent failure of the first link and the second link, a ring resiliency protocol reconfigures the ring topology such that a packet flow to be transmitted via the failed links is redirected to a fifth switch in a third adjacent pair via a third link.
