This work formally introduces the Real-Time Unsplittable Data Dissemination Problem (RTU/DDP), which is a generalization of the unsplittable flow problem. RTU/DDP problem is proved to be NP-hard. Therefore, heuristic approaches are required to acquire good solutions to the problem. The problem is divided into two sub-problems: path selection and request packing. Each of these sub-problems is formally defined and heuristic algorithms are proposed for both sub-problems. MinMin/FPF, Edge Disjoint MinMin/FPF, MinCon/FPF, and LFL-MinCon/FPF heuristics are proposed for the path selection subproblem. MNOFF and MOFF heuristics are introduced for the latter subproblem. The performances of these algorithms are compared with a genetic algorithm solution proposed in this study and a heuristic from the literature. The results and discussions of the comparisons among the performances of the proposed heuristics are presented.eninfo:eu-repo/semantics/openAccessAttribution-NonCommercial-NoDerivs 3.0 United StatesResearch Subject Categories::TECHNOLOGYArticle921067108010.12785/amis/090258
