​

The increasing demand for network services and quality across wide selections of digital applications in the internet era has caused growing congestion and raised questions about how to deal with prioritizing data in ways tailored to particular uses of applications and managing peak congestion times. Software Defined Network (SDN) in particular Slicing Strategy, seems the best solution due to its new constitution intelligently implemented through the SDN OpenFlow protocol. However, Slicing Strategies specifically “FlowVisor” are limited in certain mechanisms such as Traffic Engineering (TE), which make it a requirement to find new ways to deliver Quality of Service (QoS) for different applications. In this paper, QoSVisor presented as an SDN extension action QoS Slicer based as an enhancement to the standard FlowVisor operation slicing tools to ensure the QoS for each Slice-based class of application.
