Abstract
A method and system for identifying logical loops in an Ethernet network may determine a number of nodes N and a number of links L between nodes. A number of rings R, including a number of major rings and a number of sub-rings for the Ethernet network may be determined. Specific formulas for the values for L, R, and N may be evaluated to determine when the Ethernet network includes logical loops.
