IFIP Networking 2014 Conference

June 2-4, 2014 – Trondheim, Norway


Message from the general chairs

On behalf of the conference committees, it is our great pleasure to welcome you to Trondheim and the IFIP Networking 2014 Conference (Networking 2014). Trondheim is the third largest city in Norway. It holds a special place in Norwegian history and culture. Today, it is a modern city and technology capital of Norway with a highly respected university NTNU, many popular colleges and a research community that is rated among the best in Europe.

Networking 2014 provides a platform for the networking community from both academia and industry to discuss recent advances in the broad and quickly-evolving fields of computer and communication networks, and to highlight key issues, identify trends, and develop visions for the networking domain.

Networking 2014 is the 13th event of International Conferences on Networking sponsored by the IFIP Technical Committee on Communication Systems (TC6). It is also technically sponsored by the IEEE Computer Society. In addition, the conference has received strong institutional support from the Norwegian University of Science and Technology (NTNU), and is organized by the Department of Telematics at NTNU. Besides, the conference receives support from several patrons that include the City of Trondheim, the Research Council of Norway, Telenor, and Wireless Trondheim AS. Our sincere thanks go to them.

We thank IFIP TC6 for trusting us and giving us the opportunity to organize the conference in Norway. Without the contribution, support and help of many people, the conference and its potential success would not be possible. We are grateful to these people. Specifically, we would like to thank the IFIP TC6 Networking Steering Committee for the advice and help. We also thank the Technical Program Chairs, Bjarne E. Helvik, Deep Medhi and Bin Liu, and their technical program committee for providing the excellent technical program. Last but not least, we want to thank the rest of the Organizing Committee and people at NTNU for working hard to make sure that the conference offers the highest possible quality.

Finally, we thank you for joining us at Networking 2014 in Trondheim. We hope you take advantage of the local hospitality, meet and learn from your colleagues, and enjoy the conference and the city of Trondheim.

Message from the TPC chairs

Welcome to the IFIP Networking 2014 Conference in Trondheim, Norway.

We are very pleased to present a strong program for this year’s conference, dealing with a range of challenging and timely issues in networking. In addition to the invited keynote presentations, it consists of 55 papers presented in fourteen sessions in two parallel tracks. These were selected from 220 submitted manuscripts through a thorough review and selection process.

This work was done by a carefully selected 134 technical program committee (TPC) members from around the world, who were aided by another 179 reviewers. On average, we received 3.82 reviews per paper, with each paper receiving at least three reviews. Based on the reviews, one of the TCP members led a discussion on each of the papers among its reviewers and made a recommendation to the virtual TPC meeting held on March 11, 2014, where the final discussions were held and decisions were taken.

We would like to thank the TPC members and reviewers for their huge efforts, the General Chairs as well as the other members of the organization committee, and the IFIP Networking Conference Steering Committee for the fruitful co-operation.

We hope that you all will have an interesting and rewarding conference.

Why architecture matters to everyone: creativity on the future Internet
Jeff Burke, Assistant Dean for Technology and Innovation, School of Theater, Film and Television, University of California, Los Angeles, CA, USA


The Internet will be a fundamental substrate for human creative expression and communication in the coming decades. Even with layered protocols and a variety of programming interfaces, its core abstractions shape our notions of what is possible on the network. Through an introduction to Named Data Networking (NDN), a proposed future Internet architecture, this talk will explore the relationship of technological choices at the architectural level to critical requirements of next-generation distributed applications. NDN replaces host-based communication using IP addresses with data-centric communication using data names as the narrow waist of the Internet's "hourglass" design. Based on experience with the strengths and weaknesses of the current Internet architecture, NDN also builds in fundamental security primitives and self-regulation of network traffic. Using the cognitive dimensions framework as a guide, this talk will discuss how such new architectural features and primitives have impacted the development of prototype applications in the NDN research project, and how they could influence the emergence of innovative new applications on the Internet in the future.

About the speaker

Jeff Burke's research explores the intersections of the built environment, computer networks, and storytelling. He has produced, managed, programmed and designed performances, short films, new genre art installations and new facility construction internationally for over fifteen years, incorporating emerging technologies as part of these projects and creative works. Currently, he is Assistant Dean for Technology and Innovation at the UCLA School of Theater, Film and Television (TFT), where he has been a faculty member since 2001. Burke co-founded REMAP, a joint center of TFT and the Henry Samueli School of Engineering and Applied Science, which uses a mixture of research, artistic production, and community engagement to investigate the interrelationships among culture, community, and technology. From 2006-2012, Burke was the area lead for participatory sensing at the NSF Center for Embedded Networked Sensing (CENS). He is Co-PI and application team lead for the Named Data Networking research project, a 12-campus effort supported by the NSF Future Internet Architecture program.

Growing up in the Internet shadow - and what next?
Prof. Roch Guérin, Washington University in St. Louis, USA


Today's networking researchers are both blessed and cursed. They are blessed in that they are riding one of the most incredible wave of technology revolution of the past century; the advent of the Internet. But this is also their curse, as every new system they build or idea they propose is measured against an Internet-scale yardstick. This talk briefly reviews the rise of the Internet and the unique circumstances behind it, and argues that a similar confluence is unlikely to repeat soon. This has implications for both how networking research is evaluated, and more importantly how it can be successful. In particular, new networking research needs to be aware of the "weight" of the existing Internet ecosystem and how it influences success. Conversely, the Internet's ubiquitous presence offers an incredible source of new usages, which beg to be explored and studied. The talk uses two examples from the speaker's own research to illustrate those aspects. The first addresses the "chicken- and-egg" deployment hurdle that network technologies often face, and investigates a specific solution to tackle it. The second is based on an example of the type of questions that arise in a "networked" society, where complex interactions are the norm and understanding them becomes increasingly important.


This talks borrows from work and discussions with numerous colleagues and students. In particular, the two examples used in the talk rely on joint work with, in alphabetical order, H. Afrasiabi, J. C. de Oliveira, S. Venkatesh, and S. Weber.

Can the Internet survive the next 40 years?
Prof. Henning Schulzrinne, Columbia University, City of New York, NY, USA and US Federal Communications Commission (FCC)


The Internet and associated Internet technologies are now roughly 40 years old and have clearly become one of the core civilizational infrastructures, similar to water, electricity and transportation. It is also rapidly displacing older communication networks such as the telephone network and cable video distribution. This raises a number of important questions: What are the key attributes of the Internet that led to its success? Can the Internet be made secure? What are the economic challenges for the Internet? How can we ensure an open Internet for all? What happens when old-style networks are being replaced? What are the key challenges for the mobile Internet? The talk will try to illustrate some of the problems at the intersection of public policy, economics and engineering, motivating why addressing these issues needs contributions from all three disciplines.

End-to-end performability analysis for infrastructure-as-a-service cloud
Prof. Kishor S. Trivedi, ECE Dept., Duke University, Durham, NC, USA


Handling diverse client demands and managing unexpected failures without degrading performance are two key promises of a cloud delivered service. However, evaluation of cloud service quality becomes difficult as the scale and complexity of cloud system increases. In a cloud environment, a service request from a user goes through a variety of provider specific processing steps from the instant it is submitted until the service is fully delivered. Measurement-based evaluation is expensive especially if many configurations, workload scenarios, and management methods are to be analyzed. To overcome these difficulties, in this talk we propose a general analytic model based approach for end-to-end performability analysis of a cloud service. We illustrate our approach using Infrastructure-as-a-Service (IaaS) cloud, where service availability and provisioning delays are two key QoS metrics. A novelty of our approach is in reducing the complexity of analysis by dividing the overall model into multiple interacting stochastic process models and then obtaining the overall solution by iteration over individual sub-model solutions. In contrast to a single one-level monolithic model, our approach yields a high fidelity model that is tractable and scalable. Our approach and underlying models can be readily extended to other types of cloud services and are applicable to public, private and hybrid clouds.
