In layered networks, a single failure at a lower layer may cause multiple failures in the upper layers. As a result, traditional schemes that protect against single failures may not be effective in cross-layer networks. In this talk, we discuss the challenges in providing protection and restoration in layered networks. We show that connectivity metrics in layered networks have significantly different meaning than their single-layer counterparts. In particular, we show that results that are fundamental to survivable single-layer network design, such as the Max-Flow Min-Cut theorem, are no longer applicable to the layered setting. Thus, we propose new metrics to measure connectivity in layered networks, and develop algorithms to maximize these metrics.
