| Resumo | |
Network slicing has been a key supporting technology for resource management in modern computer networks, from 5G to 6G and beyond. Network slicing creates virtual networks over one common physical infrastructure. The dynamic resource allocation for services and slices to serve demand variations caused by user mobility is a challenge in 5G networks. Based on the described scenario, this thesis developed new resource management mechanisms for the dynamic network slicing allocation problem to support mobile users in 5G/edge computing infrastructures. The contributions of this work include: 1) one evaluation of the performance of dynamic network slicing in user mobility support scenarios; 2) a mathematical model which describes the network slices reconfiguration delays; 3) two heuristic solutions for improving the network slice reconfiguration process; and 4) a network simulator for evaluating the proposed solutions. The simulator is available as free software and has been adopted as the validation environment by the scientific community. The results of this work indicate the positive impact of slices' dynamic resource allocation in dealing with demand variations triggered by mobile users. However, the frequency of those reconfigurations is crucial to the success of such a solution. (AU) | |
