ACM CoNEXT Workshop on Emerging In-Network Computing Paradigms (ENCP)

without comments

Edge- and, more generally, in-network computing is receiving a lot attention in research and industry fora. The ability to decentralize computing, to achieve low latency communication to distributed application logic, and the potential for privacy-preserving analytics are just a few examples that motivate a new approach for looking at computing and networking.

What are the interesting research questions from a networking and distributed computing perspective? In-network computing can be conceived in many different ways – from active networking, data plane programmability, running virtualized functions, service chaining, to distributed computing. What abstractions do we need to program, optimize, and to manage such systems? What is the relationship to cloud networking?

These questions will be discussed at the first workshop on Emerging In-Network Computing (ENCP) that takes place at ACM CoNEXT-2019 on December 9th in Orlando.

We have received many interesting submission and were able to put together a really interesting program that covers both Network Programmability and In-Network Computing Architectures and Protocols. Check out the full program here.

Many thanks to my co-organizers Spyros Mastorakis and Abderrahmen Mtibaa, to our steering committee members Jon Crowcroft, Satyajayant (Jay) Misra, and Dave Oran, and to our great Technical Program Committee for putting this together.

SIGCOMM-2014 Workshop on Capacity Sharing (CSWS-2014)

without comments

The program of our Capacity Sharing Workshop at SIGCOMM-2014 (CSWS-2014, August 18th in Chicago) is online. This should be an interesting workshop — we have received many interesting submissions and were able to compile a real good program:

 

Queuing and Scheduling

  •  Revisiting Old Friends: Is CoDel Really Achieving What RED Cannot? (Nicolas Kuhn, Emmanuel Lochin and Olivier Mehani)
  • Managing Fairness and Application Performance with Active Queue Management in DOCSIS-based Cable Networks (James Martin, Gongbing Hong and James Westall)
  • WQM: An Aggregation-Aware Queue Management Scheme for IEEE 802.11n Based Networks (Ahmad Showail, Kamran Jamshaid and Basem Shihada)

Transport Protocols

  • Coupled Congestion Control for RTP Media (Safiqul Islam, Michael Welzl, Stein Gjessing and Naeem Khademi)
  • Experimental Evaluation of Multipath TCP Schedulers (Christoph Paasch, Simone Ferlin, Özgü Alay and Olivier Bonaventure)

Mobile Networks

  • ConEx Lite for Mobile Networks (Steve Baillargeon and Ingemar Johansson)
  • Mobile Network Sharing Between Operators: A Demand Trace-Driven Study (Paolo Di Francesco, Francesco Malandrino and Luiz Dasilva)
  • Network Assisted Rate Adaptation for Conversational Video over LTE, Concept and performance evaluation (Ylva Timner, Jonas Pettersson, Hans Hannu, Min Wang and Ingemar Johansson)
  • Self-clocked rate adaptation for conversational video in LTE (Ingemar Johansson)
  • Dynamic Bandwidth Allocation for Multiple Network Connections: Improving User QoE and Network Usage of YouTube in Mobile Broadband (Florian Wamser, Thomas Zinner, Phuoc Tran-Gia and Jing Zhu)

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.

Towards an Information-Centric Internet with more Things

without comments

The Internet is already made of things. However, we expect there
to be many more less-capable things, such as sensors and
actuators, connected to the Internet in years to come. In
parallel, Internet applications are more and more being used to
perform operations on named (information) objects, and various
Information-Centric Networking (ICN) approaches are being
researched in order to allow such applications to work
effectively at scale and with various forms of mobility and in
networking environments that are more challenging than a
traditional access network and data center. In a recent position
paper, we outline some benefits that may accrue, and issues that
arise, should the Internet, with many more things, make use of
the ICN approach to networking and we argue that ICN concepts
should be considered when planning for increases in the number of
things connected to the Internet.
