A method and apparatus for providing a load balanced circuit path between
a source node and a destination node within a SONET ring comprising a
plurality of nodes and connected by links by iteratively selecting
facilities within a link that have bandwidth utilization levels that are
below a threshold level. In an alternative embodiment, an alternate path
is selected in case facilities meeting the threshold level can not be
found. The threshold level is changed incrementally if facilities and
links within the first path and/or alternate path do not meet the
threshold levels.
