  • Method for fault tolerant message transmission in a computer network and computer network
    Patent number: 11115237
    Abstract: The invention describes a method and a computer network for fault tolerant message transmission. Nodes of the network are connected to form a ring network. Nodes in the network form a summation group. For transmitting messages from the nodes of the summation group to a switch edge, nodes of the summation group generate and send summation frames. If a node participating in the summation group determines the non-arrival of a summation frame, it generates first recovery frame, inserts its message into said recovery frame, and sends this first recovery frame in the direction of the summation frame, which it was expecting. After sending the first recovery frame, it generates a second recovery frame, inserts its messages into said second right direction recovery frame, and sends said second right direction recovery frame to the switch.
