Special Issue Information

Dear Colleagues,

The aim of 5G communication networks is to provide, on the same infrastructure, differentiated services to different sectors of society (vertical ecosystems), and to interconnect, over a common core network, various access networks, both wired and wireless. This infrastructure supports strong programmability, using virtualization technologies such as software-defined networks with services implemented by network function chains belonging to the control plane and user plane. Moreover, mobile edge computing, fog/edge computing, and cloud computing are fundamental elements in the 5G network architecture.

Taking into account the fact that we are at the beginning of the 5G era, with ongoing 5G projects in the installation phase around the world, in this Special Issue, we want to start a discussion around the challenges to be faced in the consolidation of technology, considering the ongoing experiences and what will be relevant to move forward with consistency in preparing communication infrastructures for the next generation.

Potential topics include but are not limited to the following:

  • Key enabling technologies and standards for 5G and beyond;
  • Extreme mobile communications for 5G and beyond: infrastructures, millimeter-wave communications, large-scale antenna arrays;
  • Specifications and standards for fronthaul/midhaul/backhaul interfaces;
  • White box hardware/software implementations for the network edge;
  • Network softwarization in 5G and beyond: slice management, NFV/SDN management and orchestration, programmable network, autonomous networks;
  • Fog and Edge for 5G and beyond;
  • Advances in cloud computing for 5G and beyond;
  • Big data services, analytics, and management for beyond 5G;
  • AI for 5G and beyond: algorithms, optimizations, and implementations;
  • Beyond 5G private networks;
  • Security in 5G and beyond: policies for privacy, anonymization of big data, reputation systems;
  • Use cases and testbeds beyond the 5G context: Ultrareliable and low-latency communication, massive machine-type communication, enhanced mobile broadband and its application in intelligent transportation systems, industrial IoT, drones and UAVs, etc.

Network function virtualization (NFV) enables network operators to save costs and flexibility by replacing dedicated hardware with software network functions running on commodity servers. There is a high need for network acceleration to achieve performance comparable to hardware, which is vital for the implementation of NFV. The necessity of NFV acceleration stems from the lengthy packet delivery path following virtualization and the unavailability of generic operating system designs to serve network-specific scenarios. Therefore, the software approach alters the operating system’s processing architecture through Kernel Bypass or offload packet processing to hardware. A typical classification scheme divides it into two main categories based on technology with software and hardware. Only these two categories can be utilized to rapidly and easily establish a classification system. However, it is difficult to suggest the specifics and peculiarities of any acceleration approach during real-world operation. For a more comprehensive classification of NFV acceleration, we refer to the ETSI NFV architectural framework in this research. As the framework clearly illustrates, the technical infrastructure layer of NFV and the corresponding management roles provides a comprehensive and intuitive view of the differences between these acceleration technologies, solutions, and initiatives. Additionally, we conducted an analysis to identify opportunities for improvement in existing solutions and propose new research programs. We expect that NFV will increasingly rely on cloud services in the future. Since cloud services do not offer a choice of hardware, our acceleration method will be primarily software-based.
