S4SI 2021 :: 4th Workshop on Advances in Slicing for Softwarized Infrastructures (S4SI)
IEEE Conference on Network Softwarization

Co-hosted at The 7th IEEE International Conference on Network Softwarization (IEEE NetSoft 2021) will be held on June 28, 2021, in Tokyo, Japan. IEEE NetSoft has been created as a flagship conference aiming at addressing "Softwarization" of networks and systemic trends concerning the convergence of Cloud Computing, Software-Defined Networking (SDN), and Network Function Virtualization (NFV).

Since its conception, S4SI has aimed at providing a focused international forum for researchers and practitioners from academia, industry, network operators, and service providers to discuss and address the advances and the challenges in the multi-faceted field of Slicing plus its emerging scenarios whereby systems, services, and workflows used in both computing and communications domains are converging and can benefit from the new techniques and strategies of infrastructure softwarization.

The current trend of convergence between computing and networking eco-systems puts software into an unprecedented and dominant role in operational communication environments. Computing, storage and connectivity services along with application instances are foreseen to be dynamically deployed in the form of slices of virtualized assets within a so-called Software-Defined Infrastructure (SDI) leveraging general-purpose processing and communication hardware, altogether being flexible managed and made available under “As-a-Service” paradigms in spirit of Cloud Computing. This concept is summarized in the idea of Slicing which has become a central piece in the evolution of telecom networks, as we witnessed in the past three editions of S4SI, as well as in other scientific and industrial venues.

The S4SI workshop addresses beyond state of the art approaches for both the advances and challenges related to Slicing in Softwarized Infrastructures, aiming for a faster and improved deployment of services in current and future 5G environments. The advances and challenges are expected to be multiple, and there are clearly many open questions that need to be addressed, including:

The proposed workshop S4SI aims at addressing the multiple open questions around the realization of end-to-end sliced softwarized infrastructures and the fundamental challenges that will facilitate the envisioned intelligent orchestration and programmability of SDIs, enabling faster deployment and efficient operation of integrated services across different resource domains. Such advances in future ecosystems, like 5G and beyond, are expected to enable dynamic establishment of generalized virtual function chains, according to service requirements.

Big Data Analytics are being applied to harness the immense stream of operational data from the Sliced infrastructure in order to perform analytics processing to improve reliability, configuration, orchestration, performance, and security management of slices. To this end, further research is needed to effectively realize the integration of Slicing with intelligent mechanisms based on data collected from the SDI itself.

The authors of the best technical papers will be invited to submit content extended versions of their papers to a fast-track reviewed at IEEE Communications Magazine series on Network Softwarization and Management (i.e. Impact Factor 2019-2020 11.052)
