چکیده
Traffic engineering issues require major adjustments, as the DiffServ architecture is gaining ground. In addition, the measurementbased strategy shows the advantages of flexibility and easy adaptation. This article reviews measurement-based packet/cell dropping schemes. Based on the definition and investigation of a “packet shortage” phenomenon, a new dropping scheme for proportionally differentiated packet loss, referred to as “debt-aware,” is proposed. Simulation results show that the new scheme curbs the effect of “packet shortage” and closely approximates loss differentiation parameters, as compared to a typical proportional dropping mechanism. More simulations have been applied to demonstrate the merits of this new method.

Advanced Networking Laboratory Virtual Queue Occupancy and Its Applications on Periodic Bandwidth On Demand Schemes for IP/SONET TR-ANL-2002-03-02
Carrying IP traffic over connection-oriented networks requires the use of bandwidth on demand schemes at gateways or network interfaces. A new virtual queue occupancy, which is more accurate than the classical one, is being proposed for IP/SONET bandwidth on demand. Based on the virtual queue occupancy, two enhanced periodic approaches for lossless services, LAVQ and LAVQL, are simulated and ev...
متن کاملAdvanced Networking Laboratory Forward Resource Reservation For QoS Provisioning in OBS Systems TR-ANL-2002-04
This paper addresses the issue of providing QoS services for Optical Burst Switching (OBS) systems. We propose a Linear Predictive Filter (LPF)-based Forward Resource Reservation method to reduce the burst delay at edge routers. An excessive reservation method is utilized to increase the successful forward reservation probability and to improve the delay reduction performance. We also discuss a...
متن کاملOn the Delay Bound of Youngest Serve First (YSF) Aggregated Packet Scheduling TR-ANL-2002-03-04
In this paper, we propose a simple scalable aggregated traffic scheduling scheme, called the Youngest Serve First (YSF) algorithm. We show analytically that YSF can provide bounded end-to-end delay time with high link utilization that may not be possible for the FIFO scheme.

متن کاملProviding Proportionally Differentiated Services over Optical Burst Switching Networks
Optical Burst Switching (OBS) is considered as an efficient switching technique for building the next generation optical Internet. An offset-time based scheme has recently been proposed in order to provide quality-of-service (QoS) in OBS networks. Unfortunately, this service differentiation has several problems. The aim of this paper is to address these problems and introduce the concept of pro...
