Накратко на български

Виртуалните мрежови функции се оптимизират чрез по-добро разполагане и паралелна работа, за да се подобри качеството на услугите в телекомуникациите. Това помага за намаляване на разходите и подобрява работата на системи като автономното шофиране и умните градове.

Optimal Orchestration of Virtualized Network Functions for Improved Quality-of-Service

The problem being addressed: This project focuses on Service Function Chain (SFC) parallelism design and efficient VNF placement to boost the NFV performance and improve QoS for telecom networks. The importance for society: Telecom networks provide vital communication infrastructure and play a key role in promoting the economic and social well-being. Network Function Virtualization (NFV) has been identified as a promising and cost-efficient solution to reduce capital expenditure (CAPEX) and operational expenses (OPEX), by decoupling traditional NFs from the proprietary equipment and running them as software-based virtualized instances, known as Virtual Network Functions (VNFs). The technologies developed in this project can serve as the theoretic tools and potential technical solutions to enhance NFV performance, and minimize OPEX and CAPEX for future network applications to address critical issues related to European and global industries such as autonomous driving, online treatment, and smart city, and hence bring benefits for the society. The overall objectives: This project aims to develop a suite of optimal VNF orchestration schemes to achieve higher NFV performance and improve the QoS of telecom networks. The specific objectives for the project “OTIS” are listed as follows: (1) establish network function chain parallelism paradigms; (2) design optimal virtualized network function placement approaches; (3) systems evaluation, prototype system and demonstration for the optimal orchestration of VNFs in NFV-based telecom networks.

Цел на проекта

Telecom networks provide vital communication infrastructure and play a key role in promoting the economic and social well-being. Network Function Virtualization (NFV) is an emerging, promising and cost-efficient technology for future Internet by decoupling the traditional network functions from dedicated hardware and running them as software-based virtualized instances, known as Virtual Network Functions (VNFs). To effectively support the emerging NFV technology, how to orchestrate VNFs and achieve improved Quality-of-Service (QoS) has become a timely burning challenge faced by the networking research community. This project aims to develop a new suite of optimal VNF orchestration schemes to boost the network performance and enhance the QoS. To this end, I will firstly design innovative Service Function Chains (SFCs) that are built from a set of chain-ordered VNFs in a parallel pattern to accelerate the network performance. Secondly, I will develop an optimal QoS-aware VNF placement approach to map the parallel SFCs into the underlying network infrastructure, which considers the important QoS metrics as a multi-objective optimization problem. Finally, I will establish a software package with two components for SFC parallelism and VNF placement and develop an experimental testbed to evaluate the proposed solutions. The scientific breakthroughs to be made in this project will contribute to provide the effective design and solution implementation of NFV network innovations. The originality of this research lies in its advocate of designing a parallel SFC paradigm and the optimization of VNF placement to satisfy the QoS requirements of ever-increasing network services. Furthermore, a series of research, training, and knowledge transfer activities will be conducted to accomplish the scientific objectives and enable me to receive professional training, broaden an interdisciplinary research background, and gain more experiences in project management and collaborations.
