Section 2.2 we introduce three different formulations for robust network design using the Γ-model. Sec-tion 3 is devoted to cut-based valid inequalities to improvethe formulations. In Section 4, we report on the computational comparison of the formulations and an evaluation of the robust network designs. We close with concluding remarks.

Recoverable Robustness in Rapid Transit Network Design
A robust network design may be too expensive to be operated in a daily basis because if there are no disruptions, a low utilization of the infrastructure may occur. Therefore, a less robust approach is proposed accounting for possible disruptions. We propose a recoverable robust network design as an

We apply them to robust network design with poly-hedral demand uncertainty, introducing the a ne routing principle. We compare the a ne routing to the well-studied static and dynamic routing schemes for robust network design. All three schemes are embedded into the general framework of two-stage network design with recourse.

Robust Multipath Source Routing Protocol (RMPSR) for Video
Two route sets are nearly disjoint, if corresponding primary routes are nearly disjoint. The basic idea behind RMPSR is to build multiple nearly disjoint route sets for the communication pair. Similar to DSR and SMR, we also use an on-demand source routing approach. The reasons for choosing source routing are that (a) it has been shown to

Furthermore, as process technology descends into the deep sub-micro realm, continued (albeit degraded) service must be provided by the network in the face of accumulating hard faults over the lifetime of the chip .

Unrestricted second stage recourse in robust network design is called dynamic routing [22, 31, 38]. Given a ﬁxed design, the commodity routing can be changed arbitrarily for every realization of the demands. Chekuri et al.  and Gupta et al.  show that allowing for dynamic routing makes robust network design intractable. More precisely
