A composable service model for lossy network elements

چکیده
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.

In this paper two R‑L network simulator configurations employing a single VDDIBA, one resistance and one grounded capacitance are presented. The first configuration is a grounded series resistor-inductor (R‑L) network simulator and the second configuration is intended for grounded parallel resister-inductor (R‑L) circuit simulation. Both the proposed circuits enjoy several beneficial features s...
متن کاملClosed-Form Solutions for Broad-Band Equivalent Circuit of Vertical Rod Buried in Lossy Grounds Subjected to Lightning Strokes
Abstract— In this paper, input impedance of a vertical rod under lightning stroke is first computed by applying the method of moments (MoM) on the Maxwell’s equations. The circuit model is then achieved through applying modified vector fitting (MVF) on the computed input impedance. After then the equivalent circuit is again extracted for a few values of soil conductivity and rod radius. Finally...
متن کاملA Fire Ignition Model and Its Application for Estimating Loss due to Damage of the Urban Gas Network in an Earthquake
Damage of the urban gas network due to an earthquake can cause much loss including fire-induced loss to infrastructure and loss due to interruption of gas service and repairing or replacing of network elements. In this paper, a new fire ignition model is proposed and applied to a conventional semi-probabilistic model for estimating various losses due to damage of an urban gas network in an eart...
متن کاملQuality of service provisioning for composable routing elements q
Quality of service (QoS) provisioning for dynamically composable software elements in a programmable router has not received much attention. We present a router platform that supports extensible and configurable routing elements, and provides them with access to given resource allocations. Scheduling issues for these elements are discussed: (1) flow-based scheduling, (2) the preemptibility of a...
