The rapid increase in network traffic with new bandwidth-hungry applications such as cloud
computing and telemedicine makes disaster survivability a crucial concern as the data (and …

Compared with fixed-grid optical network, flexible-grid optical network (FON) enabling
technologies could provide higher spectrum efficiency and thus more capacity. With more …

Risk-aware Data Replication (RDR), which replicates data at primary sites to nearby safe
backup sites, has been proposed to mitigate service disruption in a disaster area even after …

Communications networks are often disrupted by human-initiated and natural disasters such
as terrorist bombings, aerial bombardment, earthquakes, floods and volcanic eruptions …

In inter-datacenter elastic optical networks (IDC-EONs), many demands, such as data
backup, focus on being served before a specific moment rather than immediately. In …

Degraded-service-tolerant connections can operate with reduced bandwidth under failure
conditions. We propose a provisioning scheme that accepts degraded services not only …

The Ultra Dense Network (UDN), as one of key techniques in 5G, is expected to support
massive connections and offload the intense volume of data traffic. Nonetheless, the small …

In this paper, the authors propose a SDN based disaster-aware smart routing scheme for
highly-available information storage systems. The authors' proposed scheme is based on …

Risk-aware data replication (RDR), which replicates data at primary sites to safe backup
sites, has been proposed to mitigate a service disruption in a disaster area even after a …

This paper presents a method to solve the 'replication site decision problem'(RSDP) in a
short computation time in the case of multiple replicas. RSDP is a problem of finding which …
