Resilient controller and hypervisor placement for future communication networks (RESyST)
Welcome to the website of the RESyST project.
Welcome to the website of the RESyST project.
On 17 May 2018 the project leader, Ognjen Dobrijević, gave a public presentation at the Faculty of Electrical Engineering and Computing on project's research domain and specified objectives, as well as on its current scientific results and ongoing efforts. This talk, entitled "Virtualization of software-defined networks: what is the price to pay?", outlined main concepts behind software-defined networking (SDN) and network virtualization with SDN hypervisors, discussed various types of network virtualization cost/overhead that are introduced by the hypervisors, and presented the means of protecting SDN-based networks from failures, which consider these cost/overhead aspects. The talk was organized under umbrella of the IEEE Croatia Section.
The project leader, assistant professor Ognjen Dobrijević, visited KTH Royal Institute of Technology, Stockholm from 2 January to 31 March 2018 for the purposes of scientific research, professional training and project work. His visit involved joint scientific and research activities with members of the Optical Networks Lab in regard to criticality of the SDN control plane that supports network virtualization, design of protection strategies for the control plane that consider various failure types, reliability and availability analysis, and modeling of the placement problem for the control plane that may employ different protection strategies. Ognjen Dobrijević also held informal meetings with colleagues from other research institutes and industry, most notably RISE Acreo and Ericsson AB, so as to raise the project visibility.
One of the direct outcomes from his visit to KTH is the first scientific paper co-authored by all the team members, which presents results from the project activities on protecting the virtualization-centric SDN control plane from different types of failures as well as analyzing benefits and cost of the considered protection strategies. This paper was submitted to the 10th International Workshop on Resilient Networks Design and Modeling (RNDM 2018).
The project leader, assistant professor Ognjen Dobrijević, is visiting KTH - Royal Institute of Technology, Stockholm for the purposes of scientific research, professional training and project work. On 31 January 2018 he gave a public presentation on project's research objectives, planned activities and current results to members of the Optical Networks Lab and other researchers from the Communication Systems department. The goal of this presentation was to raise the project visibility and spur interest in the respective area of research.
The project co-leader, dr. Marija Furdek, visited the Faculty of Electrical Engineering and Computing from 20 December to 22 December 2017. This visit focused on project activities with respect to the identified use cases for a virtualized 5G network and the criticality of SDN-based control plane for the network operation. Furthermore, dr. Furdek gave an invited lecture under umbrella of the IEEE Croatia Section on challenges of making optical data center networks programmable and more resilient to failures.
Professor Slaviša Aleksić visited the Faculty of Electrical Engineering and Computing from 11 December to 13 December 2017 in the scope of the Erasmus+ mobility programme. This visit was used as an opportunity for the RESyST project leader, Ognjen Dobrijević, to present project activities and the planned research goals. Several areas for potential future collaboration and joint proposals have been identified, including different use cases for 5G communication networks.
On Tuesday, 14 November 2017 a gala ceremony was held in the Croatian Ministry of Science and Education. Grant agreements were awarded for 10 research projects, which were chosen by the Unity through Knowledge Fund (UKF) among 43 project proposals. The total funding approved for these projects is 2.93 million HRK.
The gala ceremony was attended by the ministry's State Secretaries, representatives of the World Bank, the Croatian Science Foundation and UKF, heads of organizations that are project beneficiaries, and project leaders. Also attending were professor Mislav Grgić, dean of the University of Zagreb, Faculty of Electrical Engineering and Computing, and assistant professor Ognjen Dobrijević, the RESyST project leader. On this occasion, Ognjen Dobrijević held a speech on the project research goals, general objectives and expected scientific impact.
