Social media, mobile devices and cloud computing are increasingly pushing conventional computer networks to their limits. Increased processing power and storage capacity have brought benefits to infrastructures with major innovations in virtualization and automation, but these benefits are often limited by networks. Given the limitations faced by network administrators, the concept of Software-Defined Networking (SDN) has emerged as a proposal for a more dynamic, manageable and adaptable approach where data and control plans are decoupled. With this uncoupling, where the control plan is centralized and the data plan is on each device, the network becomes more flexible, efficient, and ideal for high bandwidth and the dynamic nature of today’s applications. Another important aspect is the allocation of resources performed by some elements of the network to meet the demand for applications. Allocation mechanisms must be able to efficiently allocate the resources available on a network among the different applications that compete for them. In this sense, due to the standardization and adaptability proposed by the SDNs, and the limitations in the architecture of conventional networks, this dissertation proposal proposes a solution that allows the use of resource allocation models with justice in a network controller based on the SDN architecture in order to optimize mechanisms for band sharing. To validate this technique, experiments will be carried out in a virtual environment and in an experiment lab
