Abstract

We consider a packet-switched network overlaid on a wavelength-routing optical network. A pre-designed path protection scheme to restore traffic upon a single link or node failure in bidirectional rings is presented. An approach to restore affected traffic using a pre-designed logical topology that is embedded after failure on the surviving topology is discussed. We present several logical topology designs with the goal of minimizing the maximum logical distance between any two nodes. The designs are rigorously analyzed and bounds (which are tight in some cases) are presented.
