Welcome Message from Technical Program Co-Chairs
Welcome to Würzburg and the 28th International Teletraffic Congress (ITC 28).
The evolution of communication and networking is changing the world we are living in. The digital connected world is triggered by the advances on telecommunications, the penetration of the Internet, the massive deployment of mobile communications and optics, the adoption of collaborative networking and social networks, the ever-increasing speed and flexibility of new communication technologies, networks, user devices, and applications, and various operational challenges arising from this development.
ITC was established as the first international conference on networking science and practice. It gathers a wide and lively community of researchers and practitioners dedicated to pushing the envelope in the area of networking. As such, ITC has provided a forum for leading researchers from academia and industry to present and discuss the latest changes and developments in design, modelling, measurement, and performance evaluation of communication systems, networks, and services.
ITC 28 has continued this tradition, while employing some new approaches to attract high-quality papers and researchers. In particular, ITC 28 introduced the concept of areas and a demo session. ITC 28 is structured into eight different areas which address hot topics in networking. Each area is chaired by two internationally well recognized experts in that area. The area chairs organized a smaller TPC per area. The idea was that the area chairs invited experts for their areas from the ITC community as well as other well-known experts worldwide. On the one hand, the concept was aimed at expanding the ITC community and attracting high-quality submissions. On the other hand, the areas helped to improve the quality of the review process. The area chairs assigned the reviews to experts in their domain and evaluate all papers in their domain.
In addition, we introduced demo sessions for ITC 28 that cuts thematically across the areas. The demo session is distinguished from the regular sessions only in the presentation format. “Demo papers” are papers whose content is best understood by an audience if the material is demonstrated rather than presented in a lecture style slide presentation. With the demo session, we aimed to provide a different kind of interactions among the participants, so as to make ITC more attractive for other communities.
Accordingly, ITC 28 is structured into the following eight different areas and demo session with the listed chairs:
- Area 1: Smart cities and IoT (Alberto Leon-Garcia, Yanmin Zhu)
- Area 2: Cloud services and networking (Arup Acharya, Patrick Lee)
- Area 3: Mobile, wireless and 5G (Kin Leung, Thomas Hou)
- Area 4: Next generation and future Internet architectures (Michael Zink, Thomas Zinner)
- Area 5: Network and traffic management (Florin Ciucu, Peter Reichl)
- Area 6: Network design and optimization (Thomas Bauschert, Eric Wong)
- Area 7: Network measurements and analysis (Marco Mellia, Mark Squillante)
- Area 8: Networked applications (Zhu Li, Lea Skorin-Kapov)
- Demonstration Session (Mark Berman, Michael Jarschel, Rick McGeer)
ITC 28 attracted 116 international paper submissions across all areas, while 157 papers were registered. The 116 papers were submitted by authors from 33 different countries, out of which 20% were from the USA and Canada, 68% from Europe/Middle East/Africa, 11% from Asia/Pacific and the remainder from Latin America.
Each submitted paper was reviewed by at least three experts assigned by the area chairs and TPC chairs. All papers are single-blind reviewed. In special cases, when the discussion of reviewers did not converge, additional expert reviews were requested to come to a solicited decision. In total, there were 420 completed reviews for the 116 submitted papers, i.e. an average of 3.6 reviews per paper. The area chairs and TPC members fostered discussions to converge the reviewers’ recommendations towards a decision. In total, 300 discussion posts were provided for papers with diverging review scores. The area chairs provided a ranked list of papers with suggestions for papers to be accepted and rejected.
A full-day TPC meeting was held at the University of Würzburg, Germany, from 9.00 – 19.30 on May 3, 2016. The meeting was structured according to the areas. The area chairs presented the papers submitted to their area and the list of ranked papers.
Based on the reviews and the recommendations from the area chairs, it was decided during the TPC meeting which papers were to be accepted or rejected per area. In addition, for each area a few reserve papers were identified. It should be noted that those papers were also good contributions. After the discussion of all areas, the reserve papers were discussed by the physically attending TPC members in Würzburg. The papers were evaluated and compared across different areas in order to identify the best papers from among the reserve papers. If an accepted paper was flagged as needing improvement, shepherding of such papers was initiated by the area chairs. Shepherding was led by the area chairs or a TPC member assigned to a particular area.
Finally, 37 full papers were accepted out of the 108 full paper submissions, yielding an acceptance rate of 34%. In addition, 6 short demo papers were accepted. The statistics per area are given below. From among the authors of accepted papers, 28% are from USA and Canada, 61% from Europe/Middle East/Africa, 8% from Asia/Pacific and the remaining are from Latin America.
Given the accepted papers, we then group the papers according to their topics. On behalf of the Technical Program Committee (TPC), we proudly present to you an excellent technical program covering a wide range of topics which are manifested in 12 technical oral sessions and a demo session.
The technical program is presented in the form of double-track sessions spanning three days, from September 13 to 15, 2016. The demo session, the three keynote speeches, and two selected sessions are presented as plenary sessions. On the first day of the congress, September 12, 2016, a half-day workshop on Programmability for Cloud Networks and Applications (PROCON) takes place. On the final day of the congress, September 16, there are two full-day workshops: (1) 2016 International Workshop on Quality of Experience Centric Management (QCMan) and (2) Workshop of COST Action ACROSS on "Quality Engineering for a Reliable Internet of Services."
We are delighted to have three excellent keynote speakers in the main program. We thank them for agreeing to be keynote speakers and presenting their visions in spite of their busy schedules.
