Challenges of Network Slicing

By Neil Davies and Peter Thompson, Predictable Network Solutions

There are a lot of technology buzzwords about ‘network slicing’, but what do they really mean? In particular, what does a good ‘network slicing’ solution look like? What do we want from it? What capabilities are needed to deliver these requirements?

Addressing Key Challenges in 5G Networks with “Intent-Driven Networking”

By Eleni Giannopoulou, WINGS ICT Solutions, Athens, Greece; Panagiotis Demestichas, Vera Stavroulaki, University of Piraeus, Dpt of Digital Systems, School of ICT, Piraeus, Greece; Imen Grida Ben Yahia, Orange Labs, Paris, France; and Laurent Ciavaglia, Nokia Bell Labs, Paris, France

As 5G networks are expected to scale to unprecedented levels due to the increasing traffic demand and data production rate, there is a need for managing in a unified way the heterogeneity of the 5G infrastructure while at the same time supporting the introduction of new services and the management of new slices on demand. Other highly challenging aspects in today’s networks operation are the reduction of the time to deploy new services and the optimization of CAPEX/OPEX ratio.

Softwarization of Radio and Wireless Networks

By Ingrid Moerman, Spilios Giannoulis, Eli De Poorter and Xianjun Jiao, imec – Ghent University

While SDR and SDN initially were parallel evolutions happening in isolated research communities, several European projects, more specifically the H2020 projects WiSHFUL, eWINE and ORCA are currently developing enablers to bridge the gap between SDR and SDN. These projects offer advanced software and hardware platforms in open state-of-the-art large-scale wireless test facilities that can be used and further extended by academic researchers and wireless developers.

Progressive Network Transformation with RINA

By Kewin Rausch and Roberto Riggio, CREATE-NET

Nowadays, to pick up a famous quote, “the networks they are a-changing”. With the advent of mobile devices, the change of the traffic pattern (which is moving from text-based to multimedia-enhanced), the introduction of virtualization functionalities and the birth of cloud services, the network has changed immensely in just ten years. This rate of change is accelerating, which increases the necessity for a programmable and dynamic network. SDN is proposing an agile, programmable, open-standards based solution that can be used to address this problem.
