networkmodel
Network model is an abstract representation of a computer or communications network that specifies its structure, components, and behavior. It is used to analyze, design, simulate, and implement networked systems by encapsulating complexity and exposing essential interfaces and properties. A network model typically defines layers, modules, data flows, and the assumptions underlying performance measures such as delay, throughput, loss, and reliability.
Two widely known families are reference models and architectural models. Reference models organize functionality into layers
Network models serve multiple purposes: guiding system design and protocol development, providing a basis for simulation
While useful, models are simplifications and may omit rare events or complex interactions. Their usefulness depends
