Title of the thesis:
Improving resource management in Software Defined Networks
Summary:For real-time multimedia sessions, it is not possible to perform per-packet load balancing as these services are sensitive to delay and the delivery order of individual fragments. These data flows must be considered unsplittable and therefore we must use the load-balancing mechanism on a per-flow basis. In our problem representation, the individual paths of the network represent knapsacks and the individual data flows represent items. This view allowed us to design the QFLA algorithm, looking for an improved solution through reallocations that are needed. However, unlike other known solutions, the main criterion in our case is not maximizing capacity but minimizing calculation time and minimizing the number of reallocations required to achieve an improved solution. The proposed algorithm was verified in two ways - by simulating the calculations themselves with different numbers and sizes of knapsacks and objects, but also by simulating the implementation of the algorithm in the SDN.
Key words:Software defined networks, Knapsack Problem, Load Balancing
