Keynote on 'Mobile Service Evolution und Research Trends in Future Internet' Prof. Dr. Kurt Tutschku University of Vienna, Faculty of Computer Science, Chair of “Future Communication” (Funded by Telekom Austria) Universitätsstrasse 10/T11, A-1090 Vienna, Austria

Abstract:

Mobile Internet access and usage has become surprisingly fast a commodity by the Apple’s iOS and Google’s Android platforms. Hence, numerous mobile operators on the globe have experienced huge traffic increases in their networks. Network overload and network congestion have become frequent events. Such a deprivation also degrades the service experience by the users, which typically denoted as Quality-of-Experience (QoE).
A closer look at these smartphone platforms rapidly reveals that both systems still apply mainly RF technologies introduced several years ago, such as 3G UMTS or HSDPA. This characteristic is remarkable in the context of network congestions. While the current RF technologies are already capable to support even rich-media application with large amounts of data traffic, they fill up the networks. Future Mobile systems use even more sophisticated RF techniques, such as LTE or future MIMO-OFDM based systems, and might generate even higher amounts of data traffic.
This development may lead to accelerated network congestions as long as current backhaul and core net-works with today’s mechanisms for traffic management are used. As a result, the backhaul and core network architecture of next generation mobile systems, using LTE RF technology, was also new designed and is now designated as the EPC (Evolved Packet Core).
The approach to adopt the Internet Protocol (IP) technology in the LTE/EPC architecture might enable the rapid deployment of “converged” IP-based application (ideally an IP-based application doesn’t depend on the underlying connectivity) and the re-use of well-known IP traffic management techniques, but has also mixed blessing.
The increased transparency of LTE/EPC for IP-based traffic may scrutinize the business cases for LTE/EPC [Fran09] and the currently IP protocols still fall short for means for practical mechanisms quality assurance for data transport. Moreover, users don’t distinguish any more between wired and wireless systems. They take the seamless behavior and experience of services or applications for granted. As a result, they demand the same QoE for any applications in mobile and wireless systems as in today’s Internet using wired access technologies.
A major trend in today’s Internet the increased popularity of Internet streaming video websites and service, such YouTube or Hulu. While these streaming websites were in their beginning small and implemented as garage or student projects using simple server technologies, they have now grown to huge service networks, even in their size comparable to Tier-1 networks and denoted as “hyper giants”. Generally, these service networks are denoted as Content Distribution Networks (CDN). Typically, CDNs are implementing their services based on Internet’s end-to-end paradigm without the collaboration of the underlying data transport systems. Hence, the CDN services are denoted as “over-the-top (OTT)” application. Considering this characteristic, CDNs treat mobile systems as just another access network to which they connecting. However, the way of interconnecting network is essential as the difficulties of inter-domain traffic engineering shown. Thus, the questions remains open how the interconnection of future LTE/EPC-based mobile network with CDNs can be implemented such the QoE of users and the resource management of mobile network operators are fulfilled. We denoted this objective as the aim of sustained multimedia experience.
In this talk we discuss trends for mobile service evolution and research trends for the Future Internet. In particular, we will consider an example for video content distribution in in the Internet and in mobile network and discuss what one learn from recent results from Future Internet research for this use case.

Teleweaver is an integrated platform built from open source software that provides a framework for the delivery and deployment of services that are targeted specifically for marginalised communities. The system uses well known technologies such as Java EE, OSGi and the Spring framework to create digital nodes that can be deployed in underserved areas. Reed House Systems, the software firm behind Teleweaver, has strong links with academia through both Rhodes University (coe.ru.ac.za) and Fort Hare University (coe.ufh.ac.za) and uses its strategic partnerships with Siyakhula Living Labs (dwesa.org), eKhaya ICT (ekhayaict.com) and SAFIPA (safipa.com) to support and enable an ecosystem that focuses on developing culturally relevant services for the community. The demo will showcase the latest iteration of the Teleweaver system and will act as a tool to engage with researchers and application developers on how they can also get involved in the initiative.

The demand for higher data rates in fixed and mobile networks is growing continuously. A higher density of the overall wireless network coverage emerges from the maintenance of current 2G and 3G technologies and parallel deployment of the new 4G technology, namely Long Term Evolution (LTE) and Evolved Packet Core (EPC) as well as wireless LAN hotspots. The combination of the pure packet switched LTE radio and EPC requires interoperability with classic circuit switched 2G/3G mobile telecommunication core networks, to ensure seamless service usage enabled through IP Multimedia Subsystem (IMS) with VoLTE or other data services.

The 3rd International IEEE Workshop on Open NGN and IMS Testbeds 2011 (ONIT 2011) will give insights into the state-of-the-art technologies concerning open Next Generation Fixed and Mobile Broadband Packet Core Networks and Testbeds at an international scale. The objective is to evaluate and share the experience on the quality and impact of such Testbeds in order to improve current offerings and position them for future challenges. Therefore methodologies, mechanisms, concepts and research results, which address the design, deployment, prototyping and evaluation of Next Generation Fixed and Mobile Broadband Packet Core Networks (NGN), their evolution towards Future Internet (FI) and related application domains are target.

Recently, the research community and industry have been aware of the above weakness and much work has been ongoing. In this workshop we wish to bring together researchers and practitioners to share research results, advances and practical experiences under the banner of “Next Generation Network Evolution Towards Future Internet”. The workshop will act as a forum for active discussion, idea stimulation and communication.
