11th NGSDP Experts Talk “Network Slicing and Next Generation Service Programming Approaches for SDNs in 5G”
Telekom Innovation Laboratories, Winterfeldtstraße 21, 10781 Berlin, Germany
Although this technical discussion group is part of the Fachgruppe KuVS (Kommunikation und Verteilte Systeme), which is a joint committee of Gesellschaft für Informatik e.V. (GI) - German computer science society - and Informationstechnische Gesellschaft (ITG) im VDE - German Information Technology Society - and some communication or meetings will be performed in German, this page is intentionally written in English, as most of the documents, papers and slides will be only available in English.
Last Talk - 11th Meeting
Network Slicing and Next Generation Service Programming Approaches for SDNs in 5G
Friday, 22 April 2016
Location: Telekom Innovation Laboratories, Winterfeldtstraße 21, 10781 Berlin
NFV and SDN leverage the benefits of virtualization and cloud computing for networking. The technologies are rapidly maturing and first early deployments are already underway. Their deployment will fundamentally transform networking infrastructures. Using network equipment consolidated to industry-standard servers, switches and storage will turn networks into agile programmable service platforms. NFV and SDN bring important features such as network slicing and multi-tenant isolation, elastic scalability and dynamic change of network topologies to adapt to changes in traffic levels and service demands.
Upcoming network services require a new network management approach. The network management model has to move away from being low level device-oriented toward higher abstraction layers. At its core lies orchestration as enabler for dynamic network provisioning and service chaining. NFV forwarding graphs describe an abstract end-to-end service definition and specify attributes regarding like performance, capacity, resiliency. The orchestrator keeps a complete view of the infrastructure, allocates the resources for the services based on their requirements and validates network services at the expected parameters during the life cycle management and integration between legacy and virtual resources.
This shift accelerates further network convergence and also provides a framework for the transition to 5G networks. Networks will have to accommodate heterogeneous groups of users with highly divergent requirements. Use cases range over diverse areas as manufacturing, medicine, critical infrastructures or tactile Internet integrating Machine-to-Machine (M2M) and Internet of Things (IoT) services.
Resources need to be allocated to meet the specific demands of each use case. SDN, NFV and network orchestration provide here the means to implement logical Network Slices which enable operators to provide networks on an as-a-service basis and meet the wide range of use case requirements.
Emerging service platforms will have significant impact on the mobile industry but also transform the industry sectors in vertical markets enabling an unprecedented level of innovation creating new economical ecosystems. This discussion group aims to establish an active scientific SDP community in Germany addressing the involved research challenges.
- To create a scientific community in Germany and surrounding countries in the above field to discuss technical challenges and developments
- To create a forum for Master, Diploma and PhD students
- To bridge the gap between academia and industry
- To organize 2-3 work group meetings per year at different locations
Topics of Interest include (but are not limited to):
- Virtualization for various parts in the network:
- mobile core and access network
- voice and multi-media platforms (e.g., IMS, VoLTE)
- M2M and IoT platforms
- CPE for consumer and industrial applications
- End-to-end service validation for meeting end-user requirements
- Agile and dynamic service creation and deployment by SDN/NFV
- Role of orchestration in service and network management
- Challenges and opportunities for security in SDN/NFV infrastructures
- Standardization efforts within international standardization bodies and standards developing organizations
- Experiences from PoC (proof-of-concept) trials and use case implementations
- Network slicing: changes and potentials for the operator business
- Impact of vertical market demands on network architectures and services
