Abstract

Ring-based industrial networks must possess a fast recovery algorithm when either the switch node or link is faulty. This work presents a simple yet extremely fast recovery algorithm based on the last-in-backup (LIB) concept, in which the final link added to the ring is the backup link. Analysis results indicate the proposed LIB algorithm performs significantly better than the MRP protocol developed in the latest version of the IEC 62439 standard. The proposed LIB algorithm is implemented in industrial Ethernet switches as well. Our results further demonstrate that the proposed recovery algorithm is extremely feasible with a link-down recovery time of 5.5 ms for 50 switches and 6.5ms for 250 switches.
