Toward a resilient software defined infrastructure to support disastermanagement applications

Motivation and Objectives• The concept of Information‐as‐a‐Service (InfaaS) is a critical one for disaster management, before, during, and after a disaster.
• Critical need for a system that synchronizes, visualizes, and maintains different types of data, between different groups of decision makers.
• Information continuity should be maintained even as different portions of the infrastructure are compromised, thus requiring fault tolerant
components.
• The use of software‐defined techniques has the potential to offer the needed flexibility and resilience to IT infrastructures.
• The goal is to prototype a software‐defined IT infrastructure to support the continuous distributed visualization for big data analysis during adisaster.
• This is a first step in developing a large‐scale crisis informatics system that is flexible and reconfigurable depending on the needs during a disaster.

Research Plan

PRAGMA‐ENT(c) SDN testbed(b) Resource management
Since the synchronization of data
presentation
requiresquick
generation of map data fordifferent resolutions and frame
rateadjustmentforthecorresponding network streams, it
is essential to allocate anappropriate set of resources tomeet these demands. The
creation of such SDN based
infrastructure is developed on theSDN‐enhanced JMS framework,
which allows control of bothcomputationalandnetwork
resources
basedontherequirements.

Testing the robustness of the tool
on a resilient infrastructure willleverage on the PRAGMA‐ENTtestbed. This testbed is designed
for extensive network experiments
and is especially suitable for testing
the robustness of the multi‐sitevisualization tool and underlying
SDN technologies. The visualization
tool will be deployed at different
tiled display walls and connected tothe PRAGMA‐ENT through SDN‐
enabled network.

AIST(a) Multi‐site visualization tool
It is implemented as a virtual "whiteboard" or workspace where the same data is presented to multiple visualization environments in geographically distinct regions. Geographical maps are an
essential starting point of discussion among decision makers, thus as a first step, this research project will deploy a collaborative environment centered on geographical maps among multiple
large‐scale visualization devices. This multi‐site visualization tool can superimpose a large variety of geo‐ and time‐ referenced data from different sources on the geographical map, providing all
decision makers with a shared set of geo‐ and time‐referenced data.
