Summary :

Reliability of single-loop networks can be improved using double loops: forward loops advancing to the neighboring node and backward loops skipping by a certain distance. In this type of double loop networks, when some nodes break down, there exist possibilities that a message can not be transmitted to some nodes and many messages concentrate on some specific nodes to take a roundabout route. Then, the delay may happen in date transmission. These phenomena depend on the situation of faulty nodes. This paper, first, presents a routing algorithm to find a route where a message can be transmitted to the destination node when a multi-node failure arises. Next, the upper bound of transmission steps required to transmit n packets in parallel from respective starting nodes to respective destination nodes is investigated.
