Guest Editorial for Special Issue on ITU Kaleidoscope 2014: QoS and Network Crawling


The Kaleidoscope academic conference is ITU’s flagship academic event. Established in 2008, the conference brings the work of ICT researchers to the attention of the standardization community.

The conference has matured into one of the highlights of ITU’s calendar of events.

Kaleidoscope sheds light on research at an early stage in the interests of identifying associated standardization needs. Oriented towards the future, the research findings presented to the conference assist ITU in planning the course of its international standardization work.

The sixth edition of Kaleidoscope in 2014 took the theme “Living in a converged world – impossible without standards?” It was tackled from the variety of perspectives that has become essential in the context of technological and industrial convergence.

From a total of ninety-eight submissions from thirty-nine countries, a double-blind, peer-review process selected thirty-four papers for presentation at the conference, all of which were published in the Kaleidoscope Proceedings as well as the IEEE Xplore Digital Library. A selection of the best papers were also published in the March 2015 edition of IEEE Communications Magazine as part of the second issue of the Communications Standards Supplement.

This is the third in a series of three special issues to showcase extended versions of selected Kaleidoscope papers. The first addressed the theme “Towards 5G” and was published in November 2014 (Volume 2, No. 2). The second, published in March 2015 (Volume 2, No. 3), covered“Assessments, Models and Evaluation” to monitor the quality of ICT services. The first Kaleidoscope paper in this third special issue looks at the calculation of Quality of Service (QoS) parameters for two resource-intensive services – video conferencing and video on demand (VoD) – provided over 4G mobile-wireless networks. The second featured paper proposes a new webcrawling technology to identify university courses that offer education about international standardization, in addition exploring the merits of university collaboration in providing such education.

The two papers and their respective authors are as follows:

1. Algorithm for Calculating QoS Parameters of Video Conferencing and Video on Demand Services inWireless Next Generation Networks.

Vladimir Y. Borodakiy (JSC “Concern Sistemprom”, Moscow, Russia), Konstantin E. Samouylov, Irina A. Gudkova, Ekaterina V. Markova (Department of Applied Probability and Informatics, Peoples’ Friendship University of Russia, Moscow, Russia).

2. Syllabuses Crawling and Knowledge Extraction of Courses about Global Standardization Education.

Hiroshi Nakanishi (Osaka University, Japan), Tetsuo Oka (Tresbind Corporation, Japan), Yoshiaki Kanaya (Brain Gate Co. LTD, Japan).

We would like to thank the authors for their preparation of extended papers, the papers’ reviewers for their generous contribution of time and expertise, and of course the readers of this journal for their interest and feedback on this third Kaleidoscope special issue.

Readers are also encouraged to participate in the 2015 edition of ITU Kaleidoscope, “Trust in the Information Society”, to be held at the Universitat Autònoma de Barcelona, Spain, 9–11 December 2015. For more information on Kaleidoscope 2015, please consult the event’s webpage: K-2015.

Guest Editorial for Special Issue on SDN/NFV Standardization Activities


The telecommunications industry is currently undergoing a radical design change in how to build, manage, and organize networks. Instead of employing the traditional approach of a decentralized management and control plane, a more flexible management paradigm called Software Defined Networking (SDN) is favored. The SDN approach postulates the strong separation of the control plane and data plane of any network element, such as an IP router or layer 2 switch in a data center. Ideally the control plane resides in so-called SDN controllers that control via specialized control protocols the operation of the data plane elements.

This is complemented by transforming networking solutions from a purpose-built box-model design into software-based service functions running on so-called commercial off the shelve (COTS) hardware. This transformation reflects the adoption of IT system design and implementation by the networking industry and is called Network Functions Virtualization (NFV). A network function is composed of a set of function components. All these components are implemented in software for use within a virtual machine. Rapid advancements in virtualization technology, i.e., performance and user acceptance, enabled this movement. The operators will be enabled to on demand instantiate Virtual Network Functions (VNFs). That allows for a significantly reduce time delay of service on-boarding and activation. In addition, VNFs will be able to breath in order to adapt themselves to changing user demands – bothmyscaling up and down as well as scaling in and out.Aflexible service orchestration function together with a lifecycle manager is expected to realize this.

These advancements are not limited to a single technical domain, but spread across the domains of computing, networking, storage, and services in telecommunication networks and beyond. Both domains, SDN and NFV, are seeing a lot of attention in research, product development as well as standardization. Especially, since the transition to this new way of service provision and network operation can be implemented in different evolutionarysteps in any of these areas, inter-working with legacy networking elements and physical network functions needs to be foreseen; with that multiple known and new challenges of integrating these new technologies into existing deployments require standardization efforts and are of particular interest. This special issue provides several viewpoints on these emerging technology shifts by summarizing SDN/NFVstandardization efforts from multiple SDOs such ETSI ISG NFV and IRTF.

The first paper of D. Lopez and R. Krishnan presents the recently established Network Function Virtualization Research Group (NFVRG) within the Internet Research Task Force (IRTF). This accounts for the fact that many aspects of SDN and NFV are still in a stage where it is not clear what elements have to be standardized. IRTF Research Groups are tasked to explore technological spaces, which are not yet necessarily ready for standardization activities. The paper describes the process towards the creation of the NVRG, outlines the charter and concludes with an overview about the initial achievements.

K. Jijo George, A. Sivabalan, T . Prabhu, and Anand R. Prasad present and discuss an end-to-end mobile communication testbed, leveraging software that is available as part of various open source projects. The constructed testbed consists of 2G (GSM), 2.5G (GPRS/EDGE) and SAE/LTE network elements, which are operated in a virtualized computing environment. The setting is evaluated against a set of threat scenarios and test cases, and it concludes with the discussions of the results of the scenarios and test cases.

The third paper by B. Wang and M-P. Odini discusses the challenges to enable any type of Virtualized Network Functions (VNF) to work together with an ETSI Network Functions Virtualization (NFV) platform. It proposes a lightweight VNF manager solution for virtual functions in the light of a proof of concept study, based on a selected product of the author’s company.A lightweight application, calledVNEM(Virtualized Network function Element Manager) is proposed and discussed with the goal to have it open enough to be used by any VNF (Virtualized Network Function). This VNEM provides a VNF independent approach to integrate with any existing VNFs without a new EM (Element Manager) development.

The papers above are providing a snapshot of the current state of the yet evolving fields of SDN and NFV in terms of state of the standardization, early prototyping and proof of concept studies.

However, it is expected that the domains of SDN and NFV are continuing to evolve rapidly, as they conflate the traditionally separated technology domains of telecommunication networks and computing. The challengesahead are to bridge the different operational understandings of telecommunication networks, e.g., guaranteeing 99,999%uptime, versus the more relaxed approach of 20%effort to achieve 80%of the goal in the computing industry; the mapping of traditional telecommunication functions to virtualized functions in terms of their functionality, performance and reliability; the change in network management to a more comprehensive approach of managing a telecommunication network which is built on top of COTS elements as software artefacts, instead of fixed, specialized telecommunication function elements – amongst many more technological and standardization topics that are still to be addressed.
