摘      要：A conceptual design of a fault-tolerant loop network is presented. The fault-tolerance can be attributed to the use of two loops instead of one, and to a new interface design, which is unique in that it incorporates tri-state control logic that enables the network to remain operational in instances of link failures. This is accomplished by dynamically reconfiguring the logical direction of message flow through the communication links. Possible message routing algorithms are examined and compared. In addition to no-fault network operation, a discussion of fault-present operation is given with emphasis on the restructuring capabilities of the DDLCN. Simulation results are presented showing that the network has much lower message transmission times than any previous single-loop network design for no-fault operation, and remains superior for many fault-present conditions.
