Three ICCLab members were in sunny Würzburg for the ACROSS COST action meeting last week. ACROSS stands for “Autonomous Control for a Reliable Internet of Services” and our own TMB is a member of the management committee (MC) for Switzerland.
For those of you unfamiliar with COST actions, they are an instrument for research funding from the EU that provides networking opportunities for researchers.
The meeting was spread over three days with:
- The 1st ACROSS Open Workshop on Autonomous Control for the Internet of Services on Tuesday;
- Task forces and Management Committee on Wednesday;
- Plenary and work group meetings on Thursday.
The keynote speakers for the workshop gave motivating talks that spawned interesting discussions on autonomous control spanning multiple domains including mobile, compute, and application-level quality of experience (QoE). The keynote speakers were: Marco Hoffmann from Nokia Networks, Thomas Zinner from Würzburg University, and Maris van Sprang from IBM.
ICClab’s Giovanni Toffetti (that’s me!) gave a talk on the Mobile Cloud Networking (MCN) project motivation and architecture. Here are the slides I used for the talk: MCN-Vision-Scope-Architecture.
The iJoin-Project is organizing an 5G-Winter-School, hosted by the University of Bremen. As part of the very distinct and representative program, the ICCLab is invited to present the latest results of the Mobile-Cloud-Networking (MCN) project.
Some impressions and take-aways from the event.
Simone Redana, Nokia, Germany, 5G RAN Architecture for virtualization RAN
- 5G not only about radio interface (in 6GHz, etc)
- New architecture needed, generally “Multi-Radio-Cloud, Core-Cloud, using SDN-xHaul and offering API-GWs
- 5G-RAN-Cloud-Features: multi-connectivity, central radio-resource-mgt, application aware resource scheduling
- Core-Cloud-Features: NFV-enabled
- 5G features network slicing, e.g. a virtual overlay over the physical infrastructure for particular services/tenants
Clare Somerville, Intel, UK, Small Cell Forum, Small Cell Forum Advances within Network Virtualization
- Small Cell Forum (SCF) is a non-for-profit organisation fouunded in 2007, with 150+ members, current specification release is #5 (Release-5)
- Base-line: Two BIG innovations driving mobile networks, these are HetNets and NFV
- Can “virtualization” be applied to small cell architectures? SCF believes yes it can
- Small Cells to out-pace Cloud-RAN (RAN virtualization) deployments by 2019
- Major challenge is the split between the physical and virtual part of the small cell RAN
- The functional split poses requirements on the front haul technology, currently incompatible with the Ethernet-based standard deployed currently
Prof. Dr. Hans Schotten, University of Kaiserslautern, METIS
- Connected Car and Traffic Control Systems (ITS) an important 5G-Use-Case
- Human-controlled Robots 5G use case too
Ralf Irmer, Vodafone, UK
- 5G Services for Industrial Control Systems seem to bear great potential
- 5G Research Challenge, Reliability of 5G services not yet ready to support Industrial Control
- 5G Use Case Tactile Internet, requires in particular very low delay
- Software Defined Architecture (TMB: Is this something new?)
Ignacio Berberana, Telefónica I+D, Spain, iJOIN, Telefónica’s view on virtualized mobile networks
- Telco innovation largely influenced by HW
- While many mobile network architectures look simplified, in reality they need many supporting functions which make real networks much more complex
- Many new technologies never tested nor evaluated in close-to-real environments
- A combination of SDN and NFV may bring virtualization into the network/telco
- A virtualized network will require a deep transformation of company-internal structures, which was traditionally more leaning toward silos
The panel sessions will be webcast (audio and video). Questions submitted via a Twitter feed using the hashtag #ITUWORLDLIVE or by SMS or through the ITU Telecom webcast portal will be displayed on the Moderator’s laptop screen during the session.
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.
