Short Bio

David Fernandes Cruz Moura is a Communications Engineer, graduated by the Military Institute of Engineering (IME), Brazil, in 1997, with a specialization in Analysis, Project and Systems Management at the Pontifical Catholic University of Rio de Janeiro (PUC-RIO) in 2000. He also holds a Masters Degree in Electrical Engineering by the Coordination of Graduate Programs in Engineering of the Federal University of Rio de Janeiro (COPPE / UFRJ) in 2003 and a Ph.D. in Defense Engineering, in the area of Communications Systems, also from IME in 2011, after working as a visiting scholar at Virginia Polytechnic Institute and State University (Virginia Tech, USA) in 2010.

From 1997 to 2003, he worked as a communications systems development engineer at the Army Technological Center (CTEx) and was part of the team responsible for the research, design and development of Communications Intelligence (COMINT) Electronic Warfare (EW) systems. Afterwards, he worked as an instructor in Communications Systems and Computer Networks at the Agulhas Negras Military Academy (AMAN) from 2004 to 2007, being responsible for teaching, designing and implementing wireless networks, telephone systems, antennas and radio networks in military operations. After completing his Ph.D., he assumed an appointment as an assistant professor at IME, both for undergrad (Communications Engineering and Computer Engineering) and grad courses (Computing Systems), focused on Command and Control and Wireless Networking topics. In 2012, he returned to CTEx as a researcher in the Nucleus of Innovation and Research in Applied Communications to Defense (NIPCAD), recently created by the Ministry of Defense, where he served as Technical Coordinator of the Radio Defined by Software Project of the Ministry of Defense until December 2017, focusing in software development for embedded systems.

Since the end of 2017, he has been working as a postdoctoral researcher at the State University of Campinas (UNICAMP), in collaboration with the Center for Research and Development in Telecommunications (CPqD), on the theme “Integration of Software Defined Networks in Software Defined Radio “. In addition, he works as a researcher for the Novel Enablers for Cloud Slicing Project – working together with the European Union, involving 11 (eleven) universities from 4 (four) countries, focused on developing software and mechanisms for improving the cloud computing infrastructure.

Dr. Moura has an active duty in Brazilian Army, where he holds the rank of Lieutenant-Colonel. Among several distinctions, he holds the Marechal Casimiro Montenegro Filho Prize, offered in 2012 by the Secretariat for Strategic Affairs of the Presidency of the Republic, and the Oscar Niemeyer Prize, offered by the Regional Council of Engineering and Agronomy of Rio de Janeiro – both prizes offered for the best doctoral theses defended in Brazil in 2011

    ABSTRACT = {Flexibility is considered a key feature of 5G softwarization to deliver a timely response to changes in network requirements that may be caused by traffic variation, user mobility, dynamic network function chains, slice lifecycle management operations, among others. In this article, we evolve the upf-bpf1 open-source project by proposing a new design to improve its flexibility by reducing the run-time adaptation time. The project proposes an in-kernel solution based on BPF and eXpress Data Path (XDP) for 5G User Plane Function (UPF) implementations. The Just-In-Time (JIT) compilation may have a huge impact on the adaptation time due to the in-kernel verification of the BPF programs at run-time. Our results show latency improvements of around 95% to inject the BPF program into the Linux kernel. Furthermore, the solution keeps the same functionalities and delivers a packet processing performance of around 10–11 Mpps using 6 cores with almost 70% of the CPU utilization in downlink/uplink directions.},
