On 22nd April 2016 the 11th Experts Talk on Next Generation Service Delivery Platforms (NGSDP) was held at the Telekom Innovation Laboratories in Berlin. The purpose of the event is to bring together thought-leaders in the area of Next Generation Services to discuss the state of the art in the field. Continue reading
SESAME targets innovations around three central elements in 5G: the placement of network intelligence and applications in the network edge through Network Functions Virtualisation (NFV) and Edge Cloud Computing; the substantial evolution of the Small Cell concept, already mainstream in 4G but expected to deliver its full potential in the challenging high dense 5G scenarios; and the consolidation of multi-tenancy in communications infrastructures, allowing several operators/service providers to engage in new sharing models of both access capacity and edge computing capabilities.
SESAME proposes the Cloud-Enabled Small Cell (CESC) concept, a new multi-operator enabled Small Cell that integrates a virtualised execution platform (i.e., the Light DC) for deploying Virtual Network Functions (NVFs), supporting powerful self-x management and executing novel applications and services inside the access network infrastructure. The Light DC will feature low-power processors and hardware accelerators for time critical operations and will build a high manageable clustered edge computing infrastructure. This approach will allow new stakeholders to dynamically enter the value chain by acting as ‘host-neutral’ providers in high traffic areas where densification of multiple networks is not practical. The optimal management of a CESC deployment is a key challenge of SESAME, for which new orchestration, NFV management, virtualisation of management views per tenant, self-x features and radio access management techniques will be developed.
After designing, specifying and developing the architecture and all the involved CESC modules, SESAME will culminate with a prototype with all functionalities for proving the concept in relevant use cases. Besides, CESC will be formulated consistently and synergistically with other 5G-PPP components through coordination with the corresponding projects.
Active ICCLab Research Initiatives
Given the topics that will be developed during the project execution, the following research initiatives from ICCLab will contribute to SESAME.
- Cloud Orchestration: CESC Manager, VIM, monitoring and composition of services
- Software-Defined Networking: SDN-centric data-center network, integration with VIM and CESCM, VNFs
- Cloud Storage: LightDC infrastructure design, cloud storage cluster, interfaces to VIM
Horizon 2020 – Call: H2020-ICT-2014-2
Type of action: RIA
Duration: 30 Months
Start date: 1/7/2015
Project Title: SESAME: Small cEllS coordinAtion for Multi-tenancy and Edge services
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
