An analytical model for the performance evaluation of multistage interconnection networks with two class priorities

► We propose new single or multi-layered Multistage Interconnection Networks (MINs). ► Backpressure operation of MINs providing service differentiation and QoS guarantee. ► Analytical model for performance evaluation of new MINs with two class priorities. ► A new architecture of switching elements is proposed for the construction of MINs. ► Results validated by simulation are accurate for various network size and traffic.
