End-to-end service orchestration for 5G and beyond

Workshop within the 15th International Conference on Ubiquitous Computing and Communications (IUCC-2016), Granada, December 14th-16th, 2016

It is predicted that the increase in the number of end devices connected to the Internet coupled with the rapid rise of Big Data and Cloud-based services will result in increasingly vast volumes of data that have to be transported to remote locations across an interconnecting network infrastructure. This infrastructure will comprise a number of heterogeneous network domains based on a variety of technologies (ranging from cellular and wireless access networks to fibre-based core networks). In addition, the number of mobile internet users is expected to grow dramatically introducing a massive increase in mobile data, also through the adoption of Mobile Cloud Computing, where computing power and data storage are moving away from mobile devices to remote computing resources. To address these emerging requirements the 5G vision of a converged network infrastructure able to efficiently support a variety of orchestrated end-to-end services associated with both fixed and mobile users has emerged. Moreover, the cloud paradigm is also adopted to support operational purposes for radio access networks referred to as C-RAN, where large scale centralized Base Band (BB) processing is performed in the cloud. In this environment the cloud architecture is based on massively distributed antennas that have to be connected to the computational resources through a very high capacity optical fibre infrastructure that replaces the traditional backhaul network. 

As the volume and diverse requirements of these data cannot be intrinsically supported by current network solutions there is a need for a paradigm shift for the interconnecting infrastructure. The future interconnecting infrastructure needs to offer intelligent and ubiquitous connectivity between users, compute and storage resources as well as a variety of end-devices through a large-scale, high-capacity, flexible and sustainable network. In these environments greatly heterogeneous wireless access technologies (spanning from small cell to LiFi solutions) are integrated with an optical network. Optical networking plays a key role, as it offers a very high capacity, energy efficient, carrier grade transport with increased dynamicity and flexibility. However, to enable efficient and sustainable operation, this infrastructure needs to ensure flexible allocation of heterogeneous yet coordinated resources facilitating convergence between traditionally separate network domains/technologies and data infrastructures and QoS guaranteed end-to-end service orchestration mechanisms.

This workshop will cover a wide range of key issues on this topic spanning from architectural and technology challenges as well as network control and management aspects, and the role of recent technology advancements in the areas of SDN, NFV, network virtualization etc., considering various key performance indicators such as cost, QoS and QoE, energy consumption etc. Views will be presented by industrial and academic actors as well as relevant UK and EU funded research activities. The workshop is organised by the EPSRC funded Programme Grand TOUCAN.

The topics of interest related to this workshop include, but are not limited to:

  • Architectural approaches addressing convergence of heterogeneous network solutions 
  • 5G architectures supporting Cloud-RAN and functional split options
  • Convergence of end-user and operational network services, backhaul and fronthaul integration and control
  • Multi-tenancy and control of heterogeneous infrastructures
  • Dynamic capacity and mobility management
  • Service orchestration in heterogeneous infrastructures
  • Abstraction techniques over heterogeneous networks 
  • Orchestration in SDN/NFV
  • Context-aware orchestration 
  • Analytics and monitoring to support orchestration
