“…There is also a large body of work in the area of network survivability. Medhi and Tipper [13] and Metz [15], e.g., address survivability in the event of the physical destruction of the links and nodes in the network. The strategy for survivability is fast network restoration by configuring around the damaged links and nodes.…”

“…Furthermore, it is essential to model the impact of large-scale disasters and attacks against the physical infrastructure using the physical-level graph [21]. There are only a few studies that analyse graphs holistically from a multilevel point of view [46,47,52], but in very specific contexts.…”

For many years the research community has attempted to model the Internet in order to better understand its behaviour and improve its performance. Since much of the structural complexity of the Inter- net is due to its multilevel operation, the Internet's multilevel nature is an important and non-trivial feature that researchers must consider when developing appropriate models. In this paper, we compare the normalised Laplacian spectra of physical-and logical-level topologies of four commercial ISPs and two research networks against the US freeway topology, and show analytically that physical level communication networks are structurally similar to the US freeway topology. We also generate synthetic Gabriel graphs of physical topologies and show that while these synthetic topologies capture the grid-like structure of actual topologies, they are more expensive than the actual physical level topologies based on a network cost model. Moreover, we introduce a distinction between geographic graphs that include degree-2 nodes needed to capture the geographic paths along which physical links follow, and structural graphs that eliminate these degree-2 nodes and capture only the interconnection properties of the physical graph and its multilevel relationship to logical graph overlays. Furthermore, we develop a multilevel graph evaluation framework and analyse the resilience of single and multilevel graphs using the flow robustness metric. We then confirm that dynamic routing performed over the lower levels helps to improve the performance of a higher level service, and that adaptive challenges more severely impact the performance of the higher levels than non-adaptive challenges.

“…The decision can be based on either a timeout value or a token; however, it is further required that both layers are notified when failures happen. References [3] - [9] provide discussions on the survivability strategies in two-layer networks in more detail.…”

Abstract-Survivability is a critical requirement for reliable services in any network. As the Internet moves towards a three layer architecture consisting of Overlay on top of IP on top of WDM-based networks incorporating the interaction between and among network layers is crucial for efficient and effective implementation of survivability. This paper highlights the challenges of providing survivability in three-layer networks and develops a novel approach crosslayer survivable mapping to offer such survivability in an efficient way. We investigate the impacts of overlay network dependency on lower layer network layout in terms of the capacity allocated to overlay paths. The results demonstrate the impact due to layer dependency that it is more severe than initially anticipated making it clear that single layer network design is inadequate to assure service guarantees and efficient capacity allocation.
