Theory of Resource Allocation for Robust Distributed Computing
… from wide-area power or network outages These correlated failures may not only inflict a large amount of damage to the system, but they may also induce further failures in other servers as a result of the lack of reliable communication between the components of the DCS. In order to provide a …

Detecting and tolerating Byzantine faults in database systems
… independently and are thus less likely to suffer correlated failures. A final component of the scheme is a repair mechanism that can correct the state of a faulty replica, ensuring the longevity of the scheme. The main challenge in designing a replication scheme for transaction processing systems …

Modeling, analysis, and control of interdependent networks
… in the evaluation of network robustness under failures, and the design of control policies for mitigating failures, since failures may cascade from one network to another network that depends on it. We develop new models and analytical tools to study interdependent networks, with a focus on …

Design and evaluation of network survivability schemes for correlated multi-failure scenarios
… and attempt to re-establish connectivity after failures. By and large, the bulk of these solutions are only concerned with single failure recovery, i.e., either at the link or node level. In general, these are the most common types of faults events experienced in operational networks. However, …

Optimization Design for Multi-Domain Optical Network Provisioning and Survivability
… lightpath protection recovery for single-link failures by adding link-disjointness constraints at both the intra- and inter-domain levels. Finally, a novel optimization formulation is also developed to implement probabilistic lightpath protection for multiple correlated failures, i.e., as …

Domain-based Frameworks and Embeddings for Dynamics over Networks
… nodes in a critical infrastructure network where failures have occurred? Leveraging domain-based information should make it is possible to answer these questions. However, several new challenges arise, such as (a) presence of more complex dynamics. The dynamics over networks that we consider are …
