Flow-equivalent server method

In queueing theory, the flow equivalent server method (also known as flow equivalent aggregation technique,^[1] Norton's theorem for queueing networks or the Chandy-Herzog-Woo method^[2]) is a divide and conquer method to solve product form queueing networks inspired by Norton's theorem for electrical circuits.^[3] The network is successively split into two, one portion is reconfigured to a closed network and calculated.
