A Layered Queueing Network (LQN) is a modeling framework used in performance evaluation and analysis of complex systems, especially those involving computer networks, telecommunications, and service systems. It is particularly useful for analyzing systems where tasks can be processed in various layers (or stages) with different types of servers or services within each layer.
