Adaptive and Secure Network Slicing for 5G Applications and Services

Dear Colleagues,

5G will not only be an evolution of mobile broadband networks, it will bring new unique network and service capabilities by integrating networking, computing and storage resources into one programmable and unified infrastructure while serving a multitude of distributed smart devices (e.g., robots, drones, smart vehicles) and related applications, in turn being part of the infrastructure itself. Moreover, new radio capabilities will foster significantly higher throughput and lower latencies that will enable new applications in several domains, such as automotive, cloud robotics, smart cities, health, just to mention a few. This multi-facet technology evolution promises tremendous commercial opportunities for service providers provided that they enhance their network capabilities and operations toward higher scalability and flexibility to address stringent requirements of many different applications and services.

Technologies, such as Network Functions Virtualization (NFV) and Software-Defined Networking (SDN), play a prominent role in the strategic blueprint for service providers, enabling the scalable and flexible network operation demanded by application domains. Indeed, SDN allows for programmable network control and elastic allocation of the network resources. On the other hand, NFV enables software-based network functions while leveraging scalability of cloud technologies. Another correlated trend is the deployment of distributed micro-clouds located at the network edge (e.g., Edge/Fog Computing) providing service platforms to applications that need a tighter interaction with users and low latency.

A scenario can be envisioned where (telco) service providers may offer not only communication services, but also provide complete virtual networks along with distributed virtualized computing and storage resources by elastically slicing the infrastructure into partitions (i.e., network slices) customized for specific application domains. These slices will elastically deliver a composition of both network functions (e.g., security, traffic optimization, virtual radio network) and appliances (e.g., machine learning, data analytics) specialized for a specific application domain.  

To address a new set of more stringent requirements while considering the peculiarities of each application domain and industry, 5G network slices have to be deployed through intelligent control and management platforms leveraging orchestration to encompass with heterogeneous resource pools (i.e., network, compute and storage) and to cope with a dynamic context of users, services and resources. An end-to-end vision is mandatory where applications and network services are dynamically composed and flexibly provisioned across virtualized infrastructures and leveraging distributed service delivery platforms serving end-users and smart devices/terminals. Moreover, a scenario with a diversity of stakeholders involved in the provision and usage of slices will bring to novel security challenges in terms of coordination and composition of security functions. In addition, specific application domains, such as Internet of Things, or technological paradigms, such as edge computing may pose peculiar security threats.

This Special Issue calls for conceptual, theoretical and experimental contributions discussing and treating challenges that derive from such emerging scenario where systems, processes, and workflows used in both computing and communications domains are converging. The special issue welcomes contributions from both computing and network-oriented research communities, with the aim of presenting interdisciplinary approaches, innovative solutions and best practices toward a real programmatic use of virtualized infrastructures toward addressing peculiar application service platforms requirements. We invite researchers and practitioners from academia, industry, network operators, and service providers to submit papers describing original, previously unpublished work, not currently under review by another conference, workshop, or journal.
