Communications Infrastructure Recovery for Disaster Responses (slides)

Dr. Wei-Ho Chung (Academia Sinica, Taiwan)

Abstract: Unpredictable natural or manmade disasters often cause the outages of communications. The fast recovery of communications infrastructure is crucial in providing decision makers, responders, victims and general public the vital data and information for the timely responses. In traditional systems, a communication component failure may take up to hours or even days for recovery, which severely jeopardizes the requirement of timely command and control operations. In this session, we will give an overview of the modern communications recovery mechanisms, including network layer and physical layer techniques. The design considerations for the infrastructure recovery will be briefly introduced and the relevancy to the disaster management will be discussed.

Disaster Resilient Communication and Applications (slides)

Prof. Yao-Hua Ho (National Taiwan Normal University, Taiwan)

Abstract: In the last few years, we have witness many disasters which destroyed communication networks to the outside world. Wireless mesh network (WMN) is one of the best choices for establishing a network during disaster recovery. In most disaster area, the reliability of WMNs decreased rapidly due any unpredictable environment changes. The disruption of services are often introducing delay and dropping of important and live saving messages. Thus, it is desirable to have a disaster resilient network that can temporarily withstand one or multiple of failed mesh nodes. In this talk, we discuss Disaster Resilient Network (DRN) for tunnels and bridges that allows mesh clients to contribute and retain the connectivity of the network.

Dr. Yasunori Owada (NICT, Japan)

Abstract: In the Great East Japan Earthquake, weakness in the existing network have been revealed. In such emergency situation as disconnection from the core network, the local communication services should be continue among the available network infrastructures and terminals. In addition, it is required to deploy temporary network and application service as soon as possible until the recovery of damaged network system. We have been developing NerveNet as a platform that contains such features. In this presentation, the NerveNet architecture, platform and applications are introduced.

Integrated Control and Management of Disaster Emergency Response Networks (slides)

Prof. Young-Tak Kim (Youngnam University, Korea)

Abstract: The most important role of public safety communication network in disaster emergency response activity is providing the well-organized audio visual information of the disaster site for fast and efficient rescue activities. Especially when the public safety communication infra cannot provide proper broadband communications in the building basements, mountain valley area and offshore sea, ad hoc networking should be connected to the backhaul public safety communication network. In this presentation, we review the overall public safety communication network and ad hoc networking at disaster emergency rescue operations, and the integrated control and managements for realtime multimedia communications for fast and efficient rescue activities.

Large-Scale SDN Testbed over TWAREN and SDN-Based Resource Management

Prof. Li-Der Chou (National Central University, Taiwan)

Abstract: Software Defined Network (SDN) enables researchers to design novel network protocols by separating control plane and data plane and hence brings revolutionary impact to current network industry. In 2009, National Center for High-performance Computing (NCHC) started to construct a large-scale SDN Testbed over TWAREN (TaiWan Advanced Research and Education Network) backbone involving domestic and international research organizations. In order to monitor flows across different administrative domains, NCHC implemented a multi-domain automatic network topology discovery mechanism to observe network status and troubleshoot flow status. The large-scale SDN Testbed composes of seven universities and companies in Taiwan, and connects to iCAIR in US, SURFnet in the Netherlands, and JGN-X in Japan. In addition, the speaker will present his research on SDN-based cloud resource management, including load balancing, virtual network management, cloud resource control, and DoS attack mitigation.

ODENOS: A modularized SDN controller platform for multi-layer/heterogeneous networks (slides)

Dr. Masayoshi Kobayashi (NEC, Japan)

Abstract: The advent of SDN has removed the constraints brought about by rigid control protocols, thereby enabling a flexible description of control software as an SDN controller, which meets the needs of network operators. Further simplification in creating SDN controllers will become an issue in the need to create more SDN controllers quickly. This paper proposes a network abstraction model that makes it possible to simplify the description for the virtualization of network resources and the implementation of complex path control algorithms while absorbing differences in control protocols between network devices. It is also shown that an SDN controller can be created quickly and simply using the SDN controller platform prototype that was designed based on the proposed model.
