Professor Jose Marzo

Thursday, December 1 2011, 3:30 pm, DUR 1052

Abstract: This talk is mainly focused to the review single and large-scale failures in GMPLS-based networks. Society has come to rely on communications networks for business and leisure and there is high expectation on their availability and performance. Communications networks (or a part there-of) can experience failures, for example due to cables cuts or node breakdowns. These failures usually are not noticed by users thanks to effective protection and recovery mechanisms. Nevertheless, such mechanisms are not effective when large-scale multiple failures arise, that is, when a significant portion of the network fails simultaneously. In this case, in order to minimize their impact a key point is the ability to evaluate the robustness of the network, that is, to be able to assess the performance degradation that should be expected as a consequence of the failure. Robustness metrics have been proposed in the past by the research community. However, our focus is on multilayer networks featur-ing separated control and data planes, as in GMPLS. Thus, the unit of ser-vice is a connection (for example, a light path in an optical network). For this type of networks, most of the existing measures of robustness are unable to capture the real service degradation, due to they essentially rely on purely topological features.

Bio: Jose Marzo is a professor at the Computer Architecture and Technology Department at The University of Girona, Spain. He received his doctorate degree in Industrial Engineering from the University of Girona in 1997. His research interests are in the fields of communication networks, adaptive Hypermedia systems, competences based Curricula design and Quality assessment in distance learning environments. Marzo leads a research group on broadband communications and distributed systems (BCDS) at Informatics and Applications Institute (at the University of Girona)

Ben McBride

Ben McBride, former SNG member, presented the ECE Graduate Seminar on "Tamper Resistant Software"

Thursday, November 19, 2009 3:30 p.m. Rathbone Hall 1052


Anti‐tamper software techniques are designed to protect trusted code while running in a hostile environment. Proper design of anti‐tamper code, however, requires proper defense of all points in the system. A potential attacker, in contrast has the luxury of focusing attention and resources at a single point. This talk describes a case study of one anti‐tamper system — a system designed to be secure and well‐defended against many attacks but which was actually vulnerable in areas never considered by the designers. This talk will describe the software’s protection mechanisms and the solutions implemented to evade them.


Ben McBride received his B.S. in Computer Engineering from K-State in 2003. He then went to work for Garmin in the aviation software group where he developed the embedded software for their audio panel product line. In 2005, Ben returned to K-State to pursue a Master's degree with research areas in networking and machine learning. In 2007, Ben received his Master's in Electrical Engineering under the advisement of Dr. Caterina Scoglio. Since then, he has worked in the Embedded Systems Engineering group at Sandia National Labs.

Title: Virus spread in Networks

Abstract: In this presentation, the influence of the network characteristics on the virus spread is analyzed. In particular, our new model, the N-intertwined Markov chain, whose only approximation lies in the application of mean field theory, will be presented. The mean field approximation is quantified in detail. The N-intertwined model has been compared with the exact 2N -state Markov model and with previously proposed “homogeneous” or “local” models. The sharp epidemic threshold Tau_c, which is a consequence of mean field theory, is rigorously shown to be equal to Tau_c = 1 / Lambda_max(A), where Lambda_max(A) is the largest eigenvalue – the spectral radius – of the adjacency matrix A. A continued fraction expansion of the steady-state infection probability at node j is presented, as well as several upperbounds. Some concepts from algebraic graph theory, such as algebraic connectivity and isoperimetric constant, will also be introduced to explain our understanding.

Bio: Piet F. A. Van Mieghem is professor at the Delft University of Technology with a chair in telecommunication networks and chairman of the section Network Architectures and Services (NAS). His main research interests lie in new Internet-like architectures for future, broadband and QoS-aware networks and in the modelling and performance analysis of network behavior and complex infrastructures. Professor Van Mieghem received a Master's and Ph. D. in Electrical Engineering from the K.U. Leuven (Belgium) in 1987 and 1991, respectively. Before joining Delft, he worked at the Interuniversity Micro Electronic Center (IMEC) from 1987 to 1991. During 1993 to 1998, he was a member of the Alcatel Corporate Research Center in Antwerp where he was engaged in performance analysis of ATM systems and in network architectural concepts of both ATM networks (PNNI) and the Internet. He was a visiting scientist at MIT (department of Electrical Engineering, 1992-1993) and, in 2005, he was visiting professor at UCLA (department of Electrical Engineering). He was member of the editorial board of the journal Computer Networks from 2005-2006. Currently, he serves on the editorial board of the IEEE/ACM Transactions on Networking.

Epidemics, Erdos numbers, and the Internet: The structure and function of complex networks

There are networks in almost every part of our lives. Some of them are familiar and obvious: the Internet, the power grid, the road network. Others are less obvious but just as important: the patterns of friendships or acquaintances between people form a social network; the species in an ecosystem join together to form a food web; the workings of the body's cells are dictated by a metabolic network of chemical reactions. As large-scale data on these networks and others have become available in the last few years, a new science of networks has grown up, drawing on ideas from math, engineering, biology, physics and other fields to shed light on systems ranging from bacteria to the whole of human society. This lecture will look at some new discoveries regarding networks, how these discoveries were made, and what they can tell us about the way the world works.

Mark Newman received his Ph.D. in physics from the University of Oxford in 1991 and, after postdoctoral work at Cornell University, joined the staff of the Santa Fe Institute in New Mexico, a think-tank devoted to the study of complex systems. In 2002 he left Santa Fe to move to the University of Michigan in Ann Arbor. He is currently the Paul A. M. Dirac Professor of Physics at the University of Michigan as well as a professor in the university's Center for the Study of Complex Systems.

Professor Newman's research is on networks, including computer networks and social networks, and he has worked on topics as diverse as the spread of computer viruses on the Internet, the spread of human diseases over social networks, the pattern of collaborations between scientists in different fields, and the networks formed by committees in the US House of Representatives.

Title: GENI: Global Environment for Network Innovations

Date: March 8, 2007

Time: 3:30 PM

Location: 1107 Fiedler Auditorium, Fiedler Hall, Kansas State University, Manhattan KS

ABSTRACT: Despite its tremendous success, the Internet architecture is showing its age. Security is weak and the problems are worsening; availability continues to be a challenge; network management is complex and expensive; and mobile hosts are difficult to handle. Yet, researchers interested in designing new network architectures face an unfortunate catch-22. New ideas are not likely to see significant adoption without evaluation of prototype systems under realistic conditions, and yet deploying a prototype in a production network is difficult without first demonstrating the value. The GENI initiative at the U.S. National Science Foundation aims to break this cycle by providing the networking research community with a controlled and realistic environment to evaluate new network architectures. This talk will provide an overview of GENI and its three main features---virtualization, programmability, and user opt-in---as well as the current thinking about the design of the various components.

BIO: Jennifer Rexford is a Professor in the Computer Science department at Princeton University. From 1996-2004, she was a member of the Network Management and Performance Department at AT&T Labs--Research.
