ITU Telecom World 2013 – Mobile Cloud Networking Session – Outcomes

About the Mobile Cloud Networking Session. In association with the Mobile Cloud Networking project.


Mobile Cloud Networks combine mobile communications with computing to run network functions in the cloud, enabling new business models at the inflection point between mobile and internet technologies. Running mobile network functions in the cloud reduces costs, and provides elasticity, scalability, on-demand provisioning, calibration and better performance. Operators need to invest in research and human capacity, innovating to create value in-house on this new platform, developing new apps and protocols without being locked in to equipment so is now, to manufacturers. avoid the risk of The losing time market to do space as cloud computing providers begin to move into networks the fusion of telecommunications and IT is not a one-way street.

Mobile Cloud Networks
Thursday, 21 November 2013, 16:15 – 17:45, Jupiter 9

Innovative services and products over the next decade will be strongly driven by cloud computing technologies. Research communities on cloud technologies will need to address challenges such as radio access in the cloud, new opportunities for sharing of infrastructure, open source, SDN (software defined networks), new CDN (content delivery networks), and ICN (information centric networks). Globally, green requirements, performance and scalability studies and related impacts on policy, regulation and standardisation will also need to be addressed. Telecommunication networks need to be prepared for the requirements coming from cloud services, transporting the corresponding information in an effective and efficient way. The cloud concept is being brought into network architectures, by introducing virtualisation into all signal processing and information storage in the networks, and the service provision concept as a replacement for current network node functionalities. Game developers, network operators, OTT content providers and community operators will have a big role to play in these new paradigms. A broad view will be taken, addressing perspectives of innovation, standardisation, business models, implementation, roadmap, and so on.

Presenting MCN at the EU-Korea Workshop

Invited to the „Korea-EU Workshop: Exploring common research interests in the Future Internet“, 30 September, 1st and 2nd of October 2013

This event follows the 2012 ISTAG report having identified Korea as a relevant third country to jointly perform targeted research in the field of Future Internet. It also benefits from the fact that both Korea and the EU have started focused programmatic initiatives in the Future Internet domain. The purpose of this workshop is consequently: In the short term, to identify Korean and EU projects with similar scopes and objectives to favour „twinning“ and information exchanges for the mutual benefits of the running activities; in the medium term, to identify a limited and focused set of research issues of common interests in the two regions which could form the basis of specific joint research in the various upcoming implementations of the Horizon 2020 research programme.

There is an extensive track on „Innovative Internet Architectures“, and this is a perfect place to present „Mobile Cloud Networking„.

1st IEEE Workshop on Mobile Cloud Networking (MCN 2013)

The 1st Workshop on Mobile Cloud Networking (MCN 2013) will be held in conjunction with the IEEE International Conference on Communications 2013 (ICC 2013) on June 9-13, 2013, in Budapest, Hungary, see also:

The workshop will bring together researchers, engineers and users, who are interested in future mobile telecommunication networks and/or cloud computing applications and enabling technologies. MCN will discuss recent trends in telecommunication networks and cloud computing and will in particular focus on challenges to be solved when integrating these technologies as well as possible synergies of these technologies.

Access to cloud storage and computing service via wireless/mobile networks should be optimized in terms of delay, bandwidth and energy consumption from an end user perspective. Moreover, there is an increasing trend to implement more and more functions of a mobile telecommunication network in software, e.g., for signal and protocol processing. This enables to use cloud computing infrastructures as processing platform for signal and protocol processing of mobile telecommunication networks, in particular for current and future generation mobile telecommunication networks. In particular, the integration of protocol and application/service processing allows several opportunities to optimize performance of cloud applications and services observed by the mobile user, whose device is connected to the cloud via wireless access networks.

The workshop solicits original contributions in the topics of interest for the workshop. Those topics include but are not limited to the following:
Protocols and wireless network technologies for mobile cloud applications
Network virtualization for mobile cloud networks
Energy-saving at mobile end systems in network elements supporting mobile cloud applications
Distributed mobility management, including mobility prediction
Future Internet architectures and protocols for mobile cloud computing, including content-centric / context-based networking

5th GI/ITG KuVS Fachgespräch Next Generation Service Delivery Platforms

Notes of the 5th KuVS GI/ITG Workshop „NG Service Delivery Platforms“ with the topic „Advanced Service Delivery Platforms for Mobile Networks“

QoE optimization with network layer awareness on hybrid wireless networks (T. Melia, S. Randriamasy, Alcatel-Lucent, France; D. Munaretto, M. Zorzi, Univ. Padova/CFR, Italy)
– FP7 Medieval Project
– QoE based resource management in current BWA networks (LTE but also WiFi)
– Qoe Metrics for Video – Compare with reference and/or no reference
– Use the fact that different paths trough the networks means different QoE. Access/path selection based on QoE targets
– IETF ALTO (Application Layer Optimization) Working Group
— Describes attributes of caches and of their locations
— ALTO server provides ALTO clients with info on topology, routing cost, etc
– ALTO stores the network cost and needs to be combined with application layer metrics
– ALTO a tool for the operator to evaluate the performance of network caches
– In Medival ALTO not opened to users, ie operator does not reveal network-internals

Analysis of managed and OTT streaming services in mobile networks (J. Eisl, G. Kuhn, M. Lott, Nokia Siemens Networks, Germany; M. Varela, J. Prokkola, T. Mäki, J–P. Laulajainen, VTT, Finland)
Presented by M. Lott, Head of Service Control & Identity Management
– Compares „managed services“ (with QoS/QoE support by operators) and OTT services
– Different devices, different services (Mobile TV, Streaming Video, etc)
– Measurements via tcpdump, Wireshark, and tool developed by VTT
– OTT services mostly provided over HTTP, some use RTP/RTSP
– Microsoft Smoth Streaming and Apple HTTP Live Streaming are HTTP-based adaptive streaming protocols
– Conclusions: Rate adaptation not widely used, not supported by many servers, HTTP-based adaptations proprietary
– Conclusion: Managed services not significantly better than OTT services
— Paper author/NSN concludes: Means current QoS/QoE mechanisms are ineffective; more research required

FoG and Clouds: On Optimizing QoE for YouTube (T. Hoßfeld, F. Liers, T. Volkert, R. Schatz, Univ. Würzburg, Germany; Univ. Ilmenau, Germany; FTW Vienna, Austria
– Trend away from QoS towards QoE
– How to manage/optimize networks for QoE
– For HTTP-based video streaming there is no „low quality“, video will simply stall if too few resources
– Proposed: YouTube QoE metric that covers „stalling“
– Extensive study with human subjects to identify key criteria for „video quality“
– Mapping between „MOS and Number of Stalls“
– Conclusion: Users accept only very very few stalls (1 to no) and only very short stalls (exponential decrease of MOS)
– Equation for initial caching delay versus bandwidth provisioning

Application and Quality of Experience Aware Resource Management (D. Stähle, Univ. Würzburg, Germany)
– Look for ways to achieve win/win situation through network/user cooperation
– Possible with QoE as metric?
– And for Mesh-Networks?
– AquareYoumon tool by Uni Wuerzburg (Youtube QoE over mesh networks)
– YoMo – client-based application monitoring

MediaCloud – A Distributed Service Platform for Media Services (M. Bauer, S. Braun, P. Domschitz, Bell Labs, Alcatel-Lucent, Germany)
– Pardigm shift expected away from „Big Iron“ approach (datacenter centric) towards distributed „MediaCloud“
– A new approach to „building distributed services“
— Flow-driven model, Atomic execution model;
— Work on media chunks, not IP packets
– G-Streamer framework goes a bit into this direction

Seamless Service Provision in P2P Service Overlays (K. Panitzek, I. Schweizer, M. Ikramy and Max Mühlhäuser, TU Darmstadt, Germany)
– P2P service overlays – distribution and execution of applications, composition of services
– Seamless service migration between peers
– MudoCore middleware – for code migration between peers
– Chord DHT – for distributed service registry

SAP Forum 2011, Mexico City

Invited as speaker by SAPs Telco Industry Unit I had the pleasure to talk at the SAP Forum 2011 in Mexico City. Great event, well attended and even so organized.

The Telco Session was very well engaged and featured excellent speakers.
= Telco 2.0: New Business Models for Telco companies, Simon Terrance, CEO, STL Partners
= Sustainable Business for Telecom Industry, Jens Amail, SVP and Head of SAP Telecommunications Industry
= Monetizing Services in a hyper-connected World, Martin Schmid, Sales Director Convergent Charging, SAP
= Cloud Computing, New Technologies, and Co-Innovation, Thomas Michael Bohnert, Technical Director, SAP Research

An amazing speech with lots of insights was given by Simon. I especially enjoyed the discussion around Softbank, a telco that hands out femto cells plus DSL backhaul for FREE to its mobile subscribers in order to enhance mobile experience. A pure accident that femto cells were an element in my talk as well. Another interesting topic was the upstream-downstream business concept: Telcos as facilitator in the very heart of the Internet century.

Jens took on and presented SAPs strategy for the telco industry high-lightning convergent charging and and real-time analytics. Who says SAP does not have a reasonable telco footprint. With Highdeal first, and now Sybase, SAP took measures and if continued, may eventually exploit its huge experience and eco-system to become a true telco big-player.

And there was also Martin, an SAP telco veteran, making a strong case for convergent charging in a hyper-connected world, with cloud computing, mobile adds, services, or in general value-add at the forefront.

Finally, pleasure was mine to talk about tech transformations. To cut short, it was amazing to talk to an engaged crowed. The slides can be found here

ICIN 2010 in Berlin

I was attending ICIN 2010 in Berlin. My keynote on „Global Future Internet Research“ can be found on the conference website (link below).

Worthy conference with a good number of talks/attendees. Particularly interesting I found the mixture of people from research and those working on innovation and/or general management.

Few takeaways:
+ IaaS (network+storage+computing) seen as good business model for telcos in the future
+ Value of enforcing an extra revenue share from Google questionable since 25bn (Google) versus 1000bn (Telcos) is peanuts (CEO of Northstream).
+ Appstores/developer communities for telcos of limited value since Appstore mainly a tool for device sales (mobile device manufacturers)
+ Telco““““s shall better look into many smaller business models rather than looking for the next SMS-like killer app (H. Arnold, T-Labs)

The slides of the keynote speakers are meanwhile available for download

1st FOKUS FUSECO Forum 2010

I am attending the 1st FUSECO Forum in Berlin, at Fraunhofer FOKUSFUSECO Forum 2010

A few takeaways (slides at download)
HP Baumeister – Fraunhofer Digital Media Technologies, USA
+ Verizon happy to be a „bit pipe provider“ and teams-up with Skype exclusively

Franz Seiser, Deutsche Telekom AG, Germany
+ Deployment (especially integration) of EPC into existing infrastructure true challenge (despite the streamlined architecture of EPC itself)
+ Roaming (in particular IMS roaming) and QoS (different signalling) big challenge
+ Roaming primarily a European issue
+ Challenge with signalling load in LTE due to non-standard conform feature (immediate dormant mode) of smart phones (for energy saving). Operators don““““““““““““““““““““““““““““““““t have any means to control signaling in their networks
+ Another challenge related to signaling is that LTE/EPS uses Diameter exclusively and hence is not simple to integrate into existing SS7-based 2G/3G systems
+ IMS still way too much focused on fixed networks

Giulio Maggiore – Telecom Italia, Italy / ETSI TC INT Chairman, France
+ IMS & EPC Interoperability to be released by ETSI TC INT in 2011
+ Workshop 3GPP rel 8 Implementation, Deployment and Testing, 24-25 Nov 2010, Sophia Antipolis, FR

Industry panel:
Markus Beckmann, Accenture, Germany, Sven Akesson, Ericsson, Sweden, Wolfgang Hummel (Telco SM), HP, Germany, Cornel Pampu, Huawei Technologies, Germany, Bernd Wunderlich (Telco SM), IBM Deutschland, Germany
Thorsten Robrecht (Head of Global LTE), Nokia Siemens Networks, Germany, Alain Dakroub, Tekelec, France

+ NSN: currently has (global) 52% of GSM subsribers and 72% of WCDMA, currently 32 LTE networks globally (LTAM, Asia), Germany also close to forefront, NSN roughly 1M LTE basestations deployed globally, devices are already there and comercially available in weeks/month, 50% of NSNs business is already operating networks, 45K LTE basestations to be deployed by Lightsquared and operated by NSN
+ IBM: Germany decreasing telco market, question what can LTE do to solve this – generate more revenue?, Operators have to operate 2G, 2.5G, 3G and soon 4G networks but revenues shrink (~2 percent), challenge / opportunity is cloud computing for enterprises, OTT-provider kept the consumer based for them
+ HP: Offers a combined HLR+HSS product, better work with OTT (like Goolge) rather to fight them
+ Ericsson: IMS already deployed (mostly in fixed domain), Ericsson has a unit Global Services and running (deploying/operating) already hundreds of networks
+ Accenture: One challenge with these technologies is the process change that comes along with convergence (e.g. by EPC/SAE), massive impact on IT systems, changes needed in ticketing, customer support, OSS/BSS, etc, key element to address pressure of decreasing revenues is out sourcing to dedicated specialists in countries abroad (e.g. India, Asia, East-Europe) – examples engineering, operations (e.g. provisioning in shared service centers) and similar.

Q&A: Shall operators outsource core services like voice? Accenture: better not

M2M Opportunities – Lessons Learned from the US Market
Ronald M. Jubainville, Sprint, UK
+ Sprint SIP-enabled IMS network since Aug 9th 2006, First US 4G network in the US, World““““s first 3G/4G Android phone
+ What matters are devices, e.g. Mobile ATMs (average load per Mobile ATM is 6MB/month)
+ Usage-based insurance for cars with 183M users operational

Alfonso Ehijo, Telmex International, Latin America / University of Chile
+ Verizon does befriend the idea of bit-pipe provider due to compensation by several exlusive partnerships with Google, Skype, and similar content/service providers
+ Relationship (the R in smart) is what really matters (c.f. Verizon)

Roberto Minerva, Telecom Italia, Italy
+ Too many network APIs out there
+ The problem is that Telco““““s are accountable and for that make usage of network APIs complex and heavy
+ Issue is the difference between global Internet services and local communication (network) services
+ IMS will not be able to support services for business services
+ OneAPI is too late
+ Interoperability is an issue for telcos, not the users
+ WebCo(mpanies) are much faster and release alpha versions and by that involve the users early – versus – Telco““““s develop standards over years …

Q&A: There is a big opportunity in the _private_ cloud (Google is not (yet) there) says Sprint

Prof. Marc Drüner, trommsdorff + drüner, Germany
+ Marketing has to go online, „go where the customers are“, people expect the company comes to them,
+ Cool Internet App: – manage your financials using the wisdom of the crowds!
+ 75% percent of Indian youth has first contact with Internet via mobile devices
+ Extensive study of Retail Use Cases available by the company

Boaz Zilberman, fring, Israel
+ IMS is a waste of time, too complex, too heavy,
+ Mobile app industry leapfroged IMS

Sebastian Krems, ITCcon GmbH, Germany
+ Wholesale is key to the future and this means partnership
+ Wholesale industry in the telco domain behind to other industries
+ Roughly 250MB of information per year/person, total 1-2extabyte/year
+ Telco industry sustained 50% of price decline/year for the last 30 years
+ Wholesale today: long distance: doesn““““t make a good business anymore -> efficiency and scale are king; access: potential for a long-term business for investors who can sustain a steep ramp-up
+ In the future – wholesale will be all over the place!

Dr. Ralf G. Herrtwich, Daimler AG, Germany
+ The most profitable pieces in a car „integrated solutions“
+ So far web-experience in vehicles are lousy! Network doesn““““t support 200km/h ! – LTE could be the solution

Philipp Freudenberger, SAP, Germany
+ SAP about to take a bold step into the (enterprise) mobility domain (c.f. Sybase acquisition), along with SAP““““s strive for broader adoption of its solutions (goal of 1bn users by end of 2010)
+ Value chains get more and more sophisticated, increasing number of players, stakeholders, – business networks
+ How to make money out of an increasing amount of information? – Example: „from starvation to restaurant to food and payment“, „collaborative eCare“, „utilities – increased collaboration by smart cars, smart meters“, „retail – highly collaborative since customers can use real-time offer/price comparisions“

Closing Note by the Chairman – Thomas Magedanz, TU Berlin / Fraunhofer FOKUS
+ Still many open questions to be answered, especially in view of the more complex value chains in the future
+ Will there be a common platform in the future that supports this value chains and allows for collaborative value proposition?
+ This will be addressed by „Future Internet Research“ !
