摘要：in this paper we present an efficient and fair faulttolerance in ring topology to recover from token loss situation. We have two requirement in fault tolerance in ring topology (i) safety of course one node at most can use the shared link (ring) to send data at the same time (ii) livens a node requests to use the ring will eventually succeed. The proposed solution requires feedback from every other node to recover from token loss. The general idea in this paper is to enhance fault tolerance in ring topology by using queue for each node and timestamp to handle multiple requests when one of nodes uses the ring while another nodes are waiting.
