Analytic node model for deflection routing networks

An analytic model is introduced for calculating mean nodal queuing delays in deflection routed networks. In the model formulation, the authors obtain a mathematically tractable result by assuming that transit traffic arriving to the node in question possesses both spatial and temporal independence. The proposed model is applied to the SIGnet metropolitan area network. The results indicate that in typical subnetworks, reasonable accuracy may be obtained over a wide range of parameter values using link independence assumptions.
