Title: Testbed Interoperability workshop

Sub-title: Lifecycle management of experimentation

Submitted Concept and Agenda

Testbed Interoperability Workshop

Athens, 17 March 2014, pre-FIA workshop

The Internet is one of the key enablers to tackle the societal grand challenges considered within the Horizon 2020 programme addressing so-called non-ICT sectors such as Health, Energy, Transport, Inclusion, etc. It is of utmost importance that the evolution of the Internet (the “Future Internet”) takes into account these grand challenges and that the research and development in this domain gets access to advanced tools and experimental infrastructures to validate new solutions at different levels, including applications needed and developed by the mentioned sectors.

FIRE is approaching experimentation from two angles: the “FIRE facilities”, i.e. testbeds or groups of testbeds that offer services to experimenters for advanced Future Internet related experimentations; and “FIRE research projects”, which investigate new concepts and issues in relation with Future Internet, and can also, perform Future Internet experimentations. Supporting a wide range of innovative experimentations allows the right pieces to be put together, where FIRE can be considered as a critical enabler serving wide ICT and non-ICT research communities.

In this context the Fed4FIRE and OpenLab projects take the initiative to organise a workshop that will give the opportunity to interested experts meet and discuss the different aspects of the endeavour. In particular this workshop will focus on standardisation, experience reports from experimentation, and tools for experimentation. The targeted audience are owners and operators of experimental infrastructures for the Future Internet, Standardisation experts that seek to apply common tools and approaches for managing the experiments, and researchers applying an experimentally driven research towards systems and services for the Future Internet.

This workshop follows on two successful past workshops, namely the FIRE research workshop that took place in Budapest in May 2011 and the FIRE engineering workshop that took place in Ghent in December 2012.

Concept and Background

The Internet is one of the key enablers to tackle the societal grant challenges considered within the Horizon 2020 vision (Health, Energy, Transport, Inclusion ...). It is of utmost importance that the evolution of the Internet (the “Future Internet”) takes into account these grand challenges and that the research and development in this domain gets access to advanced tools and experimental infrastructures to validate new solutions at different levels.

FIRE is approaching experimentation from two angles: the “FIRE facilities”, i.e. test beds or groups of test beds that offer services to experimenters for advanced Future Internet related experimentations; and “FIRE research projects”, which investigate new concepts and issues in relation with Future Internet, and can also, perform Future Internet experimentations. Supporting a wide range of innovative experimentations allows the right pieces to be put together. In this respect FIRE is a critical enabler.

In this context the Fed4FIRE and OpenLab projects take the initiative to organise a workshop that will give the opportunity to interested experts meet and discuss the different aspects of the endeavour. In particular this workshop will focus on standardisation, experience reports from experimentation, and tools for experimentation.

This workshop follows on two successful past workshops, namely the FIRE research workshop that took place in Budapest in May 2011 and the FIRE engineering workshop that took place in Ghent in December 2012.

Target audience

In particular the work is aimed at:

  • Owners and operators of experimental infrastructures for the future Internet
  • Standardisation experts that seek to apply common tools and approaches for managing experiments
  • Researchers applying an experimentally driven research towards systems and services for the future Internet

Proposed dates

The proposed date is:

  • The workshop will be held on 17 March (whole day)

Proposed location

Athens, co-located with the Future Internet Assembly 2014 that will be held in Athens from 18-20 March 2014 organised by GRNET.

Proposed structure

It is proposed to structure the workshop in two parts:

  • Reports from experiments conducted over FIRE facilities
  • Standardisation of key operational aspects for FIRE facilities
  • Common tools for managing experiments

Proposed agenda

17 March

9:00 – 9:15 Welcome, Opening

9:15 – 10:45 Reports from experiments

In particular the experimenters will report on the experiences on deploying and managing their experiments on the FIRE infrastructures

Proposed presenters: Dr. Chrysa Papagianni, Prof. Symeon Papavassiliou (National Technical University of Athens)

  • SAViNE experiment established, prototyped and assessed a Social Network Analysis-inspired Surrogate Server placement strategy for fostering content delivery within the evolving wireless Cloud environment. Performance evaluation via experimentation was conducted over the OpenLab experimental facilities (i.e. NITOS, w-iLab.t and Planetlab Europe), with the goal to validate the benefits and operational efficiency of the proposed solution. Experimentation results provided valuable insight on the positive effect of adopting social network features for building CDNs in the cloud. Discussions on the benefits of using OpenLab facility to demonstrate the validity of the proposed approach, along with the detailed experimentation procedure and experiences or lessons learned by experimenting on OpenLab are provided.

Proposed presenters: Dr. Tim Chown, +1 (TBD).

  • OFERTIE: experiments with ROIAs on OFELIA infrastructure. The OFERTIE project is building an architecture to allow real-time interactive online application developers to take advantage of SDN capabilities present in future networks. The architecture includes an SLA manager component, and an API to allow applications to make QoS requests of the underlying infrastructure. Initial outputs include enhancements to the OpenNaaS software stack. OFERTIE plans to run experiments involving both collaborative 3D modelling and gaming applications using OFELIA infrastructure. Our presentation would include coverage of the OFERTIE architecture, the applications being adapted, use of the OFELIA testbed(s), phased experiments and results to date, and benefits and exploitation of results. Proposed presenters: Dr. Tim Chown, +1 (TBD).

11:00 – 12:30 Standardisation of key operation aspects for FIRE facilities

Presentations of current agreements with respect to access, deployment and management of experiments

Future plans for standardisation work. Identification of standardisation items

Proposed presenters: Dr. Chrysa Papagianni, Prof. Symeon Papavassiliou

  • Resource brokering system. Over the last years, there have been many efforts towards establishing federations of Future Internet experimental infrastructures with the goal to support large scale experimentation over heterogeneous environments and promote sustainability of EU and national Future Internet activities related to experimental facilities. Throughout this process, the need to provide a standard resource brokering system, supporting interoperability in federated testbeds has been identified, taking into account heterogeneous environments and infrastructures. Such a service will benefit the federation and the individual testbeds themselves, since they will have the opportunity to “advertise” their available resources (or any subset of them), while an extended user community will have the opportunity to submit requests for resources expressing them even in a more abstract way, along with their specific preferences. Experimenters - even experienced ones - will significantly benefit from this service as they will be able to simplify the overall process of identifying and reserving suitable resources for their experiments, especially in cases that they need to run large scale experiments where possibly combined resources from multiple testbeds are required to fulfil their needs (which is a key objective of the federation). Discussions on the identified benefits and challenges in deploying a resource brokering system are provided, based on experiences gained within the Fed4FIRE framework.

Proposed presenter: Prof. Vasilis Maglaris

  • NOVI - Network Innovation over Virtualized Infrastructures explores efficient approaches to compose virtualized e-Infrastructures towards a holistic Future Internet cloud service. Resources belonging to various levels, i.e. networking, storage and processing are in principle managed by separate yet inter-working providers. The presentation will provide details about the developed and validate methods, information systems and algorithms that provide users with isolated slices, baskets of resources and services drawn from federated infrastructures.

Proposed presenter: Dr. Carolina Fortuna (Jozef Stefan Institute, Ljubljana, Slovenia)

  • Common Cognitive Radio language, a CREW-GENI collaboration - Spectrum sensing hardware is available to support research experiments in several testbeds across the world including ORBIT, w-iLab.t, TWIST and LOG-a-TEC. Each testbed provides a specific mechanism to define, deploy and execute experiments making it difficult to use more than one for a specific researcher. In an attempt to decrease the definition and configuration overhead, we propose an ontology for specifying spectrum sensing experiments and show the designs decisions and abstractions used for its development. We also show how this ontology is being used in the Orbit inventory.

12:30 – 13:00 Panel and open discussion on standardisation

14:00 – 15:30 Experimentation results from the research community

Proposed presenter: Paulo Chainho (Portugal Telecom Inovação)

  • WONDER evaluates WebRTC service delivery mechanisms namely IMS and Web service delivery approaches. WONDER focuses on the interoperability of IMS and WebRTC services with each other and with standard IMS clients. The experimentations aim at clarifying which approach is most suitable and under what conditions. The experiment addresses:
  1. How to achieve signaling interoperability between different WebRTC service domains?
  2. How to manage different models of user identities and how to address peer users that reside in other WebRTC service domains?
  3. How to notify incoming communication requests when the called user is not currently logged in to a WebRTC service?

Proposed presenter: Christian Grothoff (Technische Universität München)

  • OpenLab-Eclectic: This contribution describes the experimental evaluation of a new tool for testbed management for Peer-to-Peer (P2P) applications which includes improved support for resource allocation, deployment and state-ofthe-art monitoring over a range of experimental testbeds. The presentation includes comparative results from various experiments across the different testbeds. The focus will be on three types of testbeds, HPC clusters, network emulators and Internet end-point instrumentation (PlanetLab).

Proposed presenter: René Serral (Universitat Politècnica de Catalunya)

  • Experimenting with a novel SDN approach for securing BGP routing - Securing inter-domain routing is a challenging endeavor. Unfortunately, after more than a decade of efforts for securing the routing system, it is still unclear whether the proposals under discussion at the Secure Inter-Domain Routing (SIDR) group will become adopted by ISPs. A significant part of the community recognizes many practical problems in SIDR’s solutions, most of which are related to the changes required to the BGP protocol. This presentation will provide insight about the evaluation of PSP SDN applications running on top of OPENER (Open and Programmable Environment for Experiment with Routers), with the aim of delivering security in a way that BGP is not even aware that it is being secured. The solution is based on outsourcing the inspection and control of BGP updates to an overlay network supported by the PSP. In contrast with SIDR’s proposals, SDN-based solutions require neither modifications nor extensions of BGP-4, a protocol that has proven to scale and work remarkably well for the purpose for which it was designed and which ISP are reluctant to change.

Proposed presenter: Stefano Salsano (CNIT)

  • EXPRESS has the goal of implementing an SDN infrastructure over a federation of three OpenLab testbeds (PlanetLab, NITOS and W-iLab.t) and use this infrastructure for the evaluation of its solution. The NITOS and W-iLab.t testbeds will host a number of Wireless Mesh Routers with SDN capabilities and “local” SDN controllers capable to take control of unconnected portions of the network. The PlanetLab testbed will be used to realize an SDN capable wired backbone that interconnects the Wireless Mesh Networks and hosts a “main” SDN controller.

15:45 – 17:30 Common tools for managing and controlling experiments, as well as data collection

Proposed presenter: Pedro Luis Chas Alonso (Universidad Politecnico de Madrid)

  • INFINITY CDF/XIPI: a description of the INFINITY project CDF (CDF, Common Description Model) developed as a taxonomy of FI-ICT infrastructures and used as the data model of XIPI, an open Web repository of this kind of infrastructures. A description of the CDF design principles and structure will be made and also a short demonstration will be given of the functionalities and use of XIPI. Mention also will be made of some additional algorithms implemented in XIPI related to the estimation of the degree of similarity between infrastructures and to the compatibility of an infrastructure with FIWARE.

Proposed presenter: Federico Facca (Create-NET)

  • XIFI - eXperimental Infrastructure for the Future Internet: Presentation of the experience on Building a Community Cloud to offer Future Internet services and facilities through the federation of existing Infrastructures. The presentation will provide an overview of the different interoperability issues faced and how they have been solved in the context of the project. The focus will include, in particular: Identity Management federation, Cloud regions inter networking and Infrastructure Monitoring.
