ICN Researchers Meet in Cambridge, MA

without comments


The ICN Research Group of the IRTF has met for a two day meeting in Cambridge, MA on January 13/14. More than 30 researchers from the US, Europe, China, and Japan gathered to discuss hot research topics in ICN such as:

  • Native ICN-based video streaming
  • Security (authenticated denial in ICN)
  • IoT and ICN
  • Hop-by-hop control messages in CCN
  • Named Function Networking

In addition, different groups presented updates on their current implementations and their design decisions for packet formats and ICN protocols. For CCN-based protocols further steps towards a common format have been made.

The next meeting (planned for the week of March 23rd in Dallas, at IETF-92) will continue the packet format discussion and progress new topics such as Named Function Networking.

Call for Papers: 2nd ACM Conference on Information-Centric Networking (ICN 2015)

without comments

ACM ICN 2015, September 30 - October 2, 2015, San Francisco, USA

The Call for Papers for the 2nd ACM Conference on ICN is out:


                         Call for Papers

** 2nd ACM Conference on Information-Centric Networking (ICN 2015) **


Sponsored by ACM and ACM SIGCOMM




San Francisco, USA, September 30 - October 2, 2015



Information Centric Networking (ICN) is a new network architecture intended to provide access to information without requiring an explicit binding of that information to a particular location. By directly addressing information, ICN supports mobile users and mobile networked devices, offers a higher-level communication service to applications, and promotes authentication and efficiency in the transmission and dissemination of information. Over the last few years, a global research and development community has grown around the idea of ICN.


ACM ICN 2015 is the second edition of the ACM Conference on Information-Centric Networking, which follows a series of workshops on ICN held in conjunction with the ACM Sigcomm conference.  ACM ICN 2015 is the premier international forum for researchers and practitioners to present and discuss the most recent innovations, trends, experiences, and challenges in information centric networking.  ACM ICN 2015 will be a single-track conference featuring paper and poster presentations, panel discussions, and demonstrations.


The Technical Program Committee of ACM ICN 2015 invites high-quality submissions describing unpublished research results in all aspects of ICN, with particular emphasis on contributions to architectural designs and reproducible experimental evaluations.  Papers submitted for consideration should not have been already published elsewhere and should not be under review or submitted for review elsewhere during the consideration period.

Open Standards, Open Source, Open Loop

without comments

Dave Ward (Chief Architect at Cisco) gave an interesting lunch talk on the relationship between Open Standards and Open Source Software at IETF-91 today. Technologies such as OpenFlow and NFV are increasingly being advanced through Open Source Software projects that develop both individual components as well as larger systems. The developed artifacts are  sometimes being referred to as de-facto standards.

Dave gave some perspectives on how Open Source Software can help to speed up collaborative technology development and related this to standards work in the IETF and other bodies. Dave emphasized the importance of Open Standards for the development of Internet technologies but he pointed out that Open Standards can leverage Open Source to speed up specification development and to validate architecture and protocol specifications.

The talk suggested embracing Open Source Software development for standards work in the IETF, pointing at new working models and skill sets that were required for that.

Obviously, the IETF has always had a focus on running code for validating specification and several recent efforts have been leveraging OSS succesfully -- for example CORE, DTN and many others. Still, there was agreement that there is room for extending and potentially institutionalizing this.

Capacity Sharing Workshop @ SIGCOMM 2014

without comments

Changing usage behavior, increasing demand for bandwidth as well as a continuous trend towards virtualizing networks and network functions raise questions on how to share limited capacity resources fairly and more efficiently while maintaining the best possible Quality of Experience (QoE) for users. While efficiency is most important when resources are spare, fairness need to be evaluated based on the different quality requirements of the various Internet services that we have today. For example, the Internet, especially the mobile Internet, was mostly engineered to provide a low loss service, low-latency services are not well supported today. In data centers, virtualization and high utilization promise economic benefits. However, effective, yet practical capacity sharing between tenants and applications is an important requirement. This has led to the development of enhancements in capacity sharing, especially congestion control mechanisms — some of these mechanisms are domain-specific, others lend themselves to adoption or generalization for inter-connected networks.

We are running a workshop on Capacity Sharing at SIGCOMM 2014 that invites submissions on these topics.

    Capacity Sharing Workshop 2011

    without comments

    With the increasing amount of IP traffic in fixed and mobile access networks, the question how to share the available resources in a fair, efficient and demand-oriented way becomes more and more prevalent. With the variety of services one can find in today’s Internet, the requirements in rate, data volume and latency differ strongly. To maximize resource utilization and, at the same time, provide satisfying performance to all users, application layer knowledge is needed. As different resource allocation and adaptation mechanisms already exist in MAC, transport and application layer, an integral consideration of the problem space is required.

    In wireless networks, the problem is particularly relevant due to the inherently limited resources, which render a simple “throwing bandwidth at the problem” solution impossible. Because large over-provisioning factors are economically unfeasibly, similar questions on capacity sharing also arise in fixed access networks, such as high bandwidth passive optical networks or cable networks.

    NEC Laboratories Europe and the Institute of Communication Networks and Computer Engineering (IKR) of the University of Stuttgart are organizing workshop on Capacity Sharing to address these topics. The objective of this workshop is to bring together stakeholders of mobile and fixed access networks, the classic Internet world and of the application and transport community. We solicit presentations on the state-of-the-art, results of ongoing research, open issues, trends and new ideas. We are especially looking forward to (possibly provocative) visionary presentations to foster a lively discussion about how to face the upcoming challenges in the future mobile Internet. Topics of particular interest include, but are not limited to

    • Application-layer adaption for mobile services
    • Transport layer solutions and possible interactions with cellular/fixed access networks
    • Context-aware resource allocation & cross-layer adaptation
    • QoE and fairness definitions, metrics and evaluation
    • Data traffic characteristics in fixed and mobile Internet
    • Economic aspects on capacity sharing and business models
    • Similarities and differences of capacity sharing in mobile and fixed access networks
    • Related standardization activities and projects

    The workshop takes place in Stuttgart on Thursday, October 13, 2011, and is organized by Mirja Kühlewind (IKR), Christian Mueller (IKR) and myself.
