The initiative has been established by network research centers/research labs that are participating in multiple next generation networking activities, including those developing large scale distributed experimental network research environment, such as those be implemented by such initiatives as the NSF Global Environment for Network Innovations (GENI), the EU Future Internet Research Environment (FIRE), the Japanese New Generation Internet, the Korean Future Internet initiatives, the German Future Internet Lab (G-Lab), the Brazilian future Internet initiative and others. These environments are being developed by researchers for researchers. An important goal for many of the current projects would be to have persistent global environments directly developed and managed by the research community to support their experimental research. Note On Terminology Participants in this initiative have been informed that the term was first popularized by the Princeton PlanetLab research group, who also may have invented the term, established through an early paper. Participants have also noted that a) the term "Slice" has become fairly GENI centric, b) suggested that more neutral terms be used for complementary demonstrations c) the Slice Around the World concept is one of many possible demonstrations that could be undertaken by this community.These considerations have led to the suggestion thatthe network research centers represented in this initiative create an international environment for multiple network science initiatives, experiments and demonstrations that couldshowcase Innovations in next generationcommunications and networking technologies at scale. Furthermore, these activities could be used in various locations to highlight topic areas appealing to local funding agencies. This is an important concept becausesuch activitiescan assist participants in acquiring funding for their activities. Overall Design Considerations Various aspects of design for this initiative design have been considered, including three primary components: a) showcasing one or more application capabilities, for example, some aspect of federated cloud based digital media transcoding and streaming as opposed to merely showing bit-flow graphs b) demonstrating the capabilities of programmable networks using OpenFlow, and c) designing a network architecture based on an international foundation infrastructure. Each of these components is further described in a subsequent section of this description. Also, participants in this initiative are developing a number of innovative architectural and basic technology concepts. Applications/Services A number of participants considered application and services parameters for these demonstrations. Listed here are the initial parameters. The applications/service shown must: 1) Have Striking Visuals (i.e., Not Just Showing Performance GraphsHighlighting Bit Flows) 2) Reflect the Potentials of a Truly *Global* (World-Wide) Environment 3) Closely Integrate Programmable Networking and Programmable Compute Clouds 4) Show Capabilities Not Possible to Accomplish With the General Internet or Standard R&E Networks 5) Highlight the Power of Programmable Networks, Especially Customization at the Network Edge. 6) Show a Potential for Resolving Real Current Issues vs Showing Advanced Technology, Although The Platform Is Oriented to Providing Suites Of Capabilities Consequently, the GEC 14 demonstrations will focus on applications related to creating high performance ad hoc networks integrated with could computing for scientific visualization, specifically related to nanotechnology research requiring remote steered visualizations based on real time distributed data and remote site rendering. (A second set of applications related to computational astrophysics is also being considered.) Below is an indication of why scientific visualization this fits the application parameters: 1) These applications can produce striking visual displays, however, in addition, the visuals are not merely special effect, they actually produce important information significant to the knowledge discovery process. Increasingly this is ultra high definition imaging and digital media 2) These applications reflect the potentials of having a truly world-wide environment. All major science is global in nature and requires integration of resources from around the world. 3) These applications rely on processes that closely integrate programmable networking and programmable compute clouds for data discovery, data integration, data streaming, analysis, rendering and display, in part through integration with scientific workflows. 4) These applications require capabilities not possible to provide using general Internet or standard R&E networks. 5) These applications require programmable networks, especially dynamic customization in real time at the network edge. 6) These applications demonstrate a potential for resolving an important real current issue. Advanced scientific visualization today is general accomplished in closed local systems because of the limitations of current networks. Providing capabilities for customizable high performance networking for high resolution scientific visualization based on distributed data and processes will enable a powerful new tool for scientific discovery. For Slice Around the World demonstrations, several techniques will be demonstrated. Finite Difference Time Domain(FDTD) is one of most commonly used computational electrodynamics modeling techniques for many research and industry simulations, such as LSI design electro verification. Under current HPC workflow techniques, researchers submit jobs, retrieve results, visualize those results and then resubmit the job with modifications, additional information, data, etc. Today this is a tedious, manual slow process, in part because of the limitations of todays networks. The GEC 14 demonstration will show how using dynamically programmable networks closely integrated with computational and storage clouds, it is possible to provide capabilities that can be used to create interactive simulation/visualization instruments to significantly improve this traditional process. An interactive real-time simulation/visualization instrument will include: a) distributed back-end MPI rendering clusters and storage, b) a web front end to setup control parameters for rendering and display the result, c) customized web server to pipe rendering results to users efficiently, d) a program to check the rendering result and submit jobs if the results were not produced. For Slice Around the World demonstrations, these web interfaces will be used to dynamically identify the sites around the world, where the simulation images located, to convert the request and to send the request to the appropriate host over the private international network, and interactively visualize the simulation over the private network specifically designed for the Slice Around the World demonstration. In addition, the basic service will be extended using local public network. Visualization is particularly important for nanotechnology science and engineering because those disciplines are focused on objects less than a nanometer wide. The science simulation/visualization examples that will be used are: a) Single/Double Slit Light Simulation at Nano-Macro Scale, b) Nano-Pattern Formation/Self Assembly, Photonic Band-Gap., Optical Pulse incident on Nano-particles. These topic areas are related to those that are creating new customized materials for optical components and that are designing materials that can use light to take the place of electric current used for sub component communication systems. Highly Distributed, Highly Programmable Communications Environment Based On OpenFlow Different initiative participants are developing various techniques for virtualizing distributed environments and networks, for integration, for developing control frameworks, designing network middleware and for integrating resources. Clearly, federation among these capabilities will be a major theme. As a basic capability, this initiative will create a distributed, integrated OpenFlow environment interconnected through a customized international network, which is currently being implemented. A number of the existing centers currently have OpenFlow implemented. Others are in processes of implementing OpenFlow. All sites will provide servers capable of supporting addressable VMs. Among the sites there will be a blend of static and dynamic resources. International Foundation Facilities As noted, a customized international network is currently being implemented to support this initiative. A number of the centers/labs that will be participating in this initiative are already connected through existing testbeds supported by the GLIF and GLORIAD, through a type of persistent international network research testbed facility. A process has been established to work on the connections for the others.
