KuVS Fachgespräch NGSDP

This web page informs you about all activities around the newly-created technical discussion group “NG Service Delivery Platforms & Service Overlay Networks” which is one of the expert talks of the professional group “Kommunikation und Verteilte Systeme (KuVS Fachgespräche)”. The content will be be constantly updated with a meeting log covering the timetable, agendas, logistics, slides, participant lists, minutes and photos.

8th KuVS NGSDP Expert Talk

The 8th KuVS Fachgespräch NGSDP has been jointly organized with the 42. Meeting of the ITG Expert Group (Fachgruppe) 5.2.4 “IP and Mobility” on April 17, 2013. More than 20 experts joined the presentations and discussions hosted by Vodafone in their seminar center at castle Hirschburg in Königswinter near Bonn. Nine presentations were grouped into three sessions covering network architecture, service deployment and cloud computing. The network architecture session mainly covered the latest advanced in Software Defined Networking and network virtualization including the recently emerging discussion on network function virtualization. Service creation and deployment platforms (fixed and mobile incl. device to device) were featured in the service related session in addition to service enabling technologies such as caching in mobile networks. The last session focused on bringing the network and the data center community together with networked cloud computing and its performance analysis. The detailed agenda and slides can be found here.

Motivation

In the history specific networks have featured specific service architectures. With the emergence of new network technologies the need for unified Service Delivery Platforms (SDPs) raised in order to provide value-added services seamlessly on top of these networks. In addition, reusable service building blocks have been invented to speed up service creation and delivery. In the nineties Intelligent Networks (INs) have been considered as the most important telecom SDP, which have been standardized by ITU and ETSI for fixed and mobile networks. In view of the convergence of telecommunications, Internet, IT and entertainment and the resulting more complex value chains, SDPs for the provision of converged multimedia services have become quite complex. Today there is no single SDP standardization body anymore. Whereas in the telecommunications domain the IP Multimedia System (IMS) has become the defacto standard for advanced service provision in a centralized way, in the internet proprietary over the top architectures and Peer-to-Peer (P2P) architectures promote a more distributed way of service provision. In addition the notion of Service Oriented Architectures (SOA) and open Application Programming Interfaces (APIs) in the network and on the end systems  pave the way for distributed  Service Delivery Platforms. IT and internet technologies represent today the foundation for programming services and implementing service platforms. Telco operator service provisioning is still targeting at highest reliability and availability, which is sometime in contrast to the fast beta service rollout in the Internet. New mechanisms for performance evaluation and guarantee are needed to bridge both paradigms.

In view of the new ecosystems and the “long tail” vision of services, SDPs play an important strategic role for the economy. There was a big IN research community in Germany in the nineties. Today the SDP research field seems to be fragmented and not coordinated. This discussion group aims to establish again a scientific SDP community in Germany.

Target

• 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):

• Drivers for a paradigm change in carrier networks: increasing variety of various applications for consumer and enterprise markets. Their impact and requirements on modern platforms.
• From mobile voice to mobile Internet: Reengineering mobile networks and service platforms. Do these just scale up or do we need a radical paradigm change?
• Modern carrier grade service delivery platforms including networks in the light of Fixed Mobile Convergence.
• Future-proof e2e architectures of carrier networks, data centers and service platforms.
• The role of Data Centers in such networks. Centralized versus decentralized approach. Finding the right balance.
• Stepwise virtualization and usage of cloud technologies for network and service functionalities. Future role of OpenFlow. Application aware networks. Benefits and limitations.
• Ensuring e2e privacy, security, service availability and the required Quality of Service in such environments.
• Virtualized and distributed IMS and Application Servers on their way from academia towards first applications in a large scale carrier network.
• VoLTE as a prominent example for an application in LTE networks
