NSF Award # OCI-098142 - David Jent P.I.-Indiana University

Indiana University hosted a workshop focusing on Networking and Data-centric Issues as they apply to the NSF-sponsored Campus Bridging Taskforce charter in Indianapolis, IN on April 7th. We invited the submission of position papers from the software and scientific community. Position papers served several functions. They provided a mechanism for people who could not attend the workshop to provide input to the workshop. They provided a way to enter viewpoints into the final workshop report (all position papers are to be included in the workshop report as appendices).

Networking Workshop Focus - Lead, Dave Jent (IU):

  • Find best practices where campus networking is done well
  • From the campus perspective: how to identify best practices in campus networking and end-to-end computing architecture (where that may mean lab to campus to RON to national backbone to resource hanging off of national backbones)
  • Can we also identify best practices in avoiding (or safely sitting outside) campus CI when campus cybersecurity policies are at odds with meeting research needs
  • How do you design a network for researchers when you are designing overall for the masses or for campus business operations? One particular area of discussion was how to make sensible recommendations to solve networking bottlenecks in a targeted way, rather than trying to create a campus CI that delivers the services researchers need to everyone. From the researcher’s standpoint, how do you discover what resources are available and what rational expectations are?
  • Campus intellectual property issues and safeguarding?
  • What is the role of IPv6?
  • What is the role of wireless?
  • Particular objective: create a document describing the minimal networking facilities to support research within campus and from campus to RON to national backbone networking

Data-centric Workshop Focus - Lead, Guy Almes (Texas A&M):

  • Networking design within campus and how it interacts with national trends, international trends (including technology trends of different scaling rates for different areas of technology). Specifically, how must the end-to-end network architecture meet the needs (including data access and remote visualization) stemming from Campus Bridging? Due to trends in data storage and instrumentation, the volumes of data to be moved are increasing in an aggressive exponential fashion – the (end-to-end) network will need to keep up.
  • From a researcher’s standpoint, how do I know where my data are and how do I get them? The answer to these questions must not depend on whether the data are (currently) local or remote.
  • Data storage infrastructure - what are the expectations on campuses? Issues of reliability and data management become more difficult as the quantity and complexity of data continue to grow.
  • How to handle both, a large number of small files AND a small number of large files
  • Discovery of data resources generally (in the sense of finding public and/or shareable data resources). Again, from a researcher’s standpoint, how this is requested must not depend on data location.
  • Each of the various forms of remote visualization involve some participation by the campus (perhaps ‘merely’ with excellent networking or perhaps in other ways).
  • Note: data do not equal files; services and streams matter a lot and may become very important in the future.
