  • Disaster-Aware Datacenter Placement and Dynamic Content Management in Cloud Networks 
    Sifat Ferdousi; Dikbıyık, Ferhat; M. Farhan Habib; Massimo Tornatore; Biswanath Mukherjee (OPTICAL SOC AMER, 2015)
    Recent targeted attacks and natural disasters have made disaster-resilient cloud network design an important issue. Network operators are investigating proactive and reactive measures to prevent huge data loss and service ...
  • Disaster-aware service provisioning with manycasting in cloud networks 
    S. Sedef Savas; Dikbıyık, Ferhat; M. Farhan Habib; Massimo Tornatore; Biswanath Mukherjee (SPRINGER, 2014)
    Cloud services delivered by high-capacity optical datacenter networks are subject to disasters which may cause large-area failures, leading to huge data loss. Survivable service provisioning is crucial to minimize the ...
  • Disaster-Aware Submarine Fiber-Optic Cable Deployment for Mesh Networks 
    Dikbıyık, Ferhat; Dikbıyık, Ferhat (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2016)
    With the increasing social and economic reliance on the Internet and the significant monetary and non-monetary societal cost associated with service interruption, network survivability is an important element in telecommunication ...
  • Disaster-survivable cloud-network mapping 
    Carlos Colman-Meixner; Dikbıyık, Ferhat; M. Farhan Habib; Massimo Tornatore; Chen-Nee Chuah; Biswanath Mukherjee (SPRINGER, 2014)
    Cloud-computing services are provided to consumers through a network of servers and network equipment. Cloud-network (CN) providers virtualize resources [ e. g., virtual machine (VM) and virtual network (VN)] for efficient ...
  • Earthquake Preparedness Strategies for Telecom Backbone with Integration of Early Warning Systems and Optical WDM Networks (Invited Paper) 
    Dikbıyık, Ferhat; Küyük, Hüseyin Serdar (IEEE, 2016)
    In this study, we explore three different strategies for such situation; 1) Extreme approach that reprovisions all connections in danger with full or degraded bandwidth, 2) relax approach that reprovisions only critical ...
  • Exploiting Excess Capacity for Survivable Traffic Grooming in Optical Backbone Networks 
    Dikbıyık, Ferhat; Tornatore, Massimo; Mukherjee, Biswanath (OPTICAL SOC AMER, 2014)
    Backbone networks usually have some excess capacity (EC) to accommodate traffic fluctuations and to avoid early capacity exhaustion. Network operators can exploit EC in optical wavelength division multiplexed (WDM) backbone ...
  • Exploiting Excess Capacity, Part II: Differentiated Services Under Traffic Growth 
    Dikbıyık, Ferhat (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2015)
    Connections provisioned in a backbone network are usually protected. A "good" protection scheme can decrease the downtime experienced by a connection, which can reduce (or eliminate) penalties for the violation of the ...
  • International Conference on the Design of Reliable Communication Networks DRCN 
    Dikbıyık, Ferhat (IEEE, 2016)
    Today's cloud system are composed of geographically distributed datacentcr interconnected by high-speed optical networks. Disaster failures can severely affect both the communication network as well as datacenters ...
  • Joint Progressive Recovery of Optical Network and Datacenters After Large-Scale Disasters 
    Sifat Ferdousi; Dikbıyık, Ferhat; Massimo Tornatore; Biswanath Mukherjee (IEEE, 2017)
    Effective post-disaster cloud-network recovery can significantly improve users' access to important cloud services. We propose a joint progressive recovery strategy for optical network and datacenters to maximize content ...
  • Minimizing the Risk From Disaster Failures in Optical Backbone Networks 
    Dikbıyık, Ferhat; Massimo Tornatore; Biswanath Mukherjee (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2014)
    Failures caused by disasters (e.g., weapons of mass destruction (WMD) attacks, earthquakes, hurricanes, etc.) can create huge amount of loss and disruptions in optical backbone networks. Due to major network disruptions ...
  • Network Adaptability from Disaster Disruptions and Cascading Failures 
    Biswanath Mukherjee; M. Farhan Habib; Dikbıyık, Ferhat (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2014)
    Disasters can cause severe service disruptions due to large-scale correlated cascading failures in telecom networks. Major network disruptions due to disasters - both natural (e. g., Hurricane Sandy, 2011 Japan Tsunami) ...
  • Network Adaptability to Disaster Disruptions by Exploiting Degraded-Service Tolerance 
    S. Sedef Savas; M. Farhan Habib; Massimo Tornatore; Dikbıyık, Ferhat; Biswanath Mukherjee (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2014)
    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 revenue) loss caused by large-scale ...
