The development of scalable service models for integrated services networks is crucial for fostering interoperability and competition among multiple network service providers that support quality of service. A key scalability property of a service model is composability, which allows models for network elements in tandem to be lumped together into a composite model which is of the same type as the constituent service models. We present a new service model for lossy network elements, and show that it is composable. To illustrate the new service model, we characterize some fundamental network elements in terms of it.
