Design and evaluation of network survivability schemes for correlated multi-failure scenarios
Wireline high-speed networks have become a critical part of modern cyberinfra-structures and provide the base substrates to support a full range of higher-layer user services and applications. Indeed, a wide range of technologies have been deployed in these domains, ranging from ultra-fast Internet …

Network-layer Selective Security
<p>The Internet and other large computer networks have become an integral part of numerous daily processes. Security at the network layer is necessary to maintain infrastructure survivability in the case of cyber attacks aimed at routing protocols. In order to minimize undesired overhead associated …

Efficient orchestration of data centers via comprehensive and application-aware trade-off exploration
Software-defined network (SDN) orchestration, the problem of integrating and deploying multiple network control functions (NCFs) while minimizing suboptimal network states that can result from competing NCF proposals, is a challenging open problem. In this work, we formulate SDN orchestration as a …

Survivability in layered networks
In layered networks, a single failure at the lower (physical) layer may cause multiple failures at the upper (logical) layer. As a result, traditional schemes that protect against single failures may not be effective in layered networks. This thesis studies the problem of maximizing network …
