Geographical correlated failures are threats that cause major interruptions and damage to
networking systems. To mitigate this rarely addressed challenge, this letter presents a novel …

Regional failures, such as natural disaster or malicious attack, have become a major threat
to the construction of future reliable communication network. The regional failures usually …

Routing policies used in the Internet tend to be restrictive, limiting communication between
source-destination pairs to one path, when often better alternatives exist. To avoid route …

Multi-path routing is effective to enhance network availability, by selecting multiple failure-
independent paths for reaching one destination in the hope to survive individual path …

Multi-path routing is effective to enhance network availability, by selecting multiple failure-
independent paths for reaching one destination in the hope to survive individual path …

During large geographic events in networks, the routing churn that occurs has been shown
to cause significant impacts in routing stabilization following the event. This work proposes a …

Large-scale geographical events can significantly disrupt network services. In particular, the
routing churn that occurs during such large-scale events has been shown to cause …

Telecommunication networks have to deal with fiber cuts, hardware malfunctioning and
other failures on a daily basis, events which are usually treated as isolated and unrelated …

In this paper we study the problem of enabling uninterrupted delivery of messages between
endpoints, subject to spatially correlated failures in addition to independent failures. We …

Due to their importance to society, communication networks should be built and operated to
withstand failures. However, cost considerations make network providers less inclined to …
