ABSTRACT:
Methods and apparatus for substantially minimizing single points of failure for circuit paths in networks with mixed protection schemes are disclosed. According to one aspect of the present invention, a method for routing circuit paths between a source and a destination of a network includes identifying a first available circuit path between the source and the destination. The first available circuit path includes a first plurality of links which each have an associated protection type. The method also includes determining a number protection changes associated with the first plurality of links, and assigning a first metric to the first available path that is based on the number of protection changes. Finally, the method includes identifying a selected available path to be used to pass information between the source and the destination based at least in part on the first metric.
