Presentation Award Winners

Incorporating X509 Security-Certificate Based Authentication into the Shibboleth Authentication Mechanism by Veerendra Shirole, University of Missouri

This presentation discusses the current state of federations and CI collaboration efforts in the Internet2 community. It includes an update on the opportunities and benefits of some new activities in the InCommon Federation along with an update on progress being made in supporting collaboration efforts in the Great Plains Network. The focus is on making it easier to facilitate collaborations in federated environments. In addition to providing a more general update on the status of federations among higher education institutions, as well as some industrial partners, this talk also identifies some of the impediments to widespread use of CI infrastructure on a regional or larger scale. Some proposed solutions to these problems will be introduced so that talks that discuss recent implementations by graduate students at the University of Missouri can be presented.

Fault Tolerant and Highly Available Entitlement Server for CI Collaboration by Harcharan Singh, University of Missouri

Managing identities and authorizing access to services is facilitated by the Shibboleth System to provide collaboration capabilities across multiple organizations and institutions. The service provider component of a Shibboleth-enabled environment is used, in part, for authenticating users. An entitlement server is a server application that is used during the authorization process by a service provider. The entitlement server keeps records about users having various entitlements. A service provider can send a query to an entitlement server to check if a user has a particular entitlement. Upon return the SP has a yes or no answer with which it makes further decisions about providing a particular service or not. An entitlement server can handle entitlements from multiple virtual organizations. Currently, a single entitlement server is used to check the entitlements of users. One drawback of using a single entitlement server is that the service provider must be aware of the location where the entitlement server is available. Moreover, a single entitlement server does not support fault tolerance. The failure of the entitlement server results in the authorization process failure.

GpENI@UNL: UNL Contributions to a Regional Testbed by Mukesh Sudabee, University of Nebraska, Lincoln

GpENI Demonstration by Justin Rohrer, University of Kansas

The Great Plains Environment for Network Innovation (GpENI) is an international programmable network testbed centered on a regional optical network in the Midwest US, providing flexible infrastructure across the entire protocol stack to enable research in Future Internet Architecture. This poster and demonstration provides an overview to the architecture, topology, operation, and use of GpENI. GpENI is funded in part by the US National Science Foundation GENI (Global Environments for Network Innovation) program and by the EU FIRE (Future Internet Research and Experimentation) Programme.

Viral Conductance: Quantifying the robustness of networks with respect to virus spread by Mina Youssef, Kansas State University

Many complex networks are considered robust but yet vulnerable to different types of attacks. In this paper, we focus on the robustness of networks to the spread of viruses. The epidemic threshold is a classical measure of network robustness. It does not only neglect number of infected nodes at steady state, but also all possible attack strengths that can harm the network. We introduce a new network robustness measure called Viral Conductance VC, which measures the vulnerability of networks to all possible effective infection rates and the corresponding number of infected nodes at the steady state. We also propose a heuristic to compute VC for large networks with high accuracy. Upper and lower bounds of VC are derived based on the network topological characteristics. We determine the viral conductance of regular graphs, complete bi-partite graphs, scale-free graphs, watts-strogatz graphs and a number of realistic networks, and we compare them with the robustness value obtained from the heuristic. We classify the networks according to their robustness to the spread of virus, and we show that the spectral radius is not a sufficient metric to measure network robustness.

Honorable Mention

Towards Storage Optimization on Email Server by Daehee Kim, University of Missouri, Kansas City

As email is becoming the most prominent method of today’s communication and the volume of emails is ever increasing, this is leading to a need for larger storage space for mail boxes. Toward optimizing storage demands, we propose a simple yet effective de-duplication approach for email servers. We have analyzed a cooperate email data set, and observe that a significant portion of emails are destined to multiple recipients that would cause duplicate copies of a same message in an email server. We propose to filter such emails and store them in a shared mailbox. Each recipient will have only a pointer to the pool. A recipient counter maintains how many users have access to the email, and when the count becomes zero, the email is removed from the shared mailbox. We have implemented the email de-duplication scheme using linux sendmail and milter. The approach has a number of advantages over an existing email storage optimization technique –i.e., MS exchange single instance store that reduces redundancies within one database of a server. They include i) low implementation complexity, ii) low operational overhead, and iii) de-duplication over an entire server level. The proposed approach may be further enhanced with other finer granular techniques such as attachment level or block level de-duplication techniques.

GpENI Experimentation, A Testbed to Support Renewable Energy by Ali Sydney, Kansas State University

One of the objectives of the Wind for Schools program, supported by the DOE National Renewable Energy Center Laboratory, is to equip academic institutions with the knowledge and skill to study and subsequently, contribute to advancements in the development and deployment of renewable resources. In particular, turbines have been installed at nine schools in Kansas including Concordia, KSU, and Sterling, just to name a few. With this in mind, our goal in this demonstration is to utilize the GpENI aggregate to support this initiative by providing dedicated network resources and the expertise necessary to support this venture.
