[Apologies if you got multiple copies of this invitation] The Fourth International workshop on Software Defined Networks and Network Function Virtualization (SDN-NFV 2020) <http://emergingtechnet.org/SDN-NFV2020/> in conjunction with The Seventh International Conference on Software Defined Systems (SDS-2020) <http://emergingtechnet.org/SDS2020/> Paris, France. April 20-23, 2020 (Technically Co-Sponsored by IEEE France Section) *SDN-NFV 2020 CFP* The emerging networking techniques such as Software Defined Network (SDN) and Network Function Virtualization (NFV) are promising a complete paradigm shift in how we manage our future networks. With their enormous benefits which include reducing the operational cost, better resources utilization and easier management requirements, the adoption of such technologies is gaining momentum. Supported by a well-defined basis such as network virtualization and the decoupling of the data and control planes, the integration of SDN and NFV with current systems might be a straightforward process. However, this might incur many challenges which require deep analysis to propose creative solutions. In the (SDN-NFV 2020) workshop, we are aiming to invite researchers from both the academia and the industry to present their state-of-the-art research efforts and findings and to open the doors for discussion about how to contribute of the advancement of this important research field. The Fourth International workshop on Software Defined Network and Network Function Virtualization (SDN-NFV) will be a forum for scientists, researchers, students, and practitioners to present their latest research results, ideas, developments, and applications in the areas of SDN, NFV, 5G, Internet of Things (IoT) and Edge Computing. We are mainly interested in receiving state of the art work on different aspect of SDN and NFV management system, security and privacy, cloud computing and big data supported SDN and NFV, to mention but few. The topics of interest of the workshop include, but are not limited to: * Software Defined Network (SDN) Architectures and Design * Network Function Virtualization (NFV) Architectures and Design * SDN-NFV Integration * SDN-NFV Orchestration * SDN-NFV Based Control plane design * SDN-NFV Based Data plane design * SDN-NFV Performance Management * SDN-NFV support for Cloud based DataCenter * SDN-NFV support for 5G Networks * SDN-NFV support for Internet of Things (IoT) * SDN-NFV support for Big Data Computing * SDN-NFV support for large scale storage system * Hardware system design for SDN-NFV * SDN-NFV Security management * Radio Access Network virtualization * SDN-NFV in access networks * Edge and Fog Computing * Cloud Computing * Case studies *Submission* Papers selected for presentation will appear in the SDN-NFV and SDS Proceedings, which will be submitted to IEEE Xplore for inclusion. Papers must be 6 pages max in IEEE format, 10pt font using the IEEE 8.5" x 11" two-column format, single space, A4 format. All papers should be in PDF format, and submitted electronically at Paper Submission Link. A full paper must not exceed the stated length (including all figures, tables and references). Submitted papers must present original unpublished research that is not currently under review for any other conference or journal. Papers not following these guidelines may be rejected without review. Also submissions received after the due date, exceeding length limit, or not appropriately structured may also not be considered. Authors may contact the Program Chair for further information or clarification. *Important Dates:* Submission Date: 1st February, 2020 (Extended) Notification to Authors: 28th February, 2020 Camera Ready Submission: 10th March, 2020 Please send any inquiry on SDN-NFV 2020 to the Emerging Tech.
