Overbooking becomes feasible because user applications tend to overestimate their resources and requirements, that tends to utilize only a fraction of the allocated resources. Overbooking has to be carefully planned in order not to impact application performance. Resource utilization and Data centers utilization can be used in this overbooking scheduler. Data send can send from sources to destination via node. Resource utilization and allocated capacity can be increased by 50% with acceptable performance degradation. Fuzzy logic functions are used to check each overbooking decisions and estimate it.
