....priority dropping provides no incentives for receivers to lower their subscription level. 3 Simulation methodology and results We have examined the behavior of MFQ under a variety of conditions. We use an assortment of traffic sources and topologies. All simulations were performed in ns 2 [20], which provides accurate packet level implementation for various network protocols. 3.1 Non responsive multicast flows We start by validating MFQ for a simple topology consisting of a single congested link connecting two routers n1 and n2 and having a capacity C equal to 10 Mbps and a ....

....SIMULATION METHODOLOGY AND RESULTS We have examined the behavior of MFQ under a variety of conditions. We use an assortment of traffic sources and topologies. Due to space limitations, we only report on a small sampling of the simulations we have run . All simulations were performed in ns 2 [7], which provides accurate packet level implementation for various network protocols. All algorithms used in the simulation, expect MFQ, were part of the standard ns 2 distribution . Without loss of generality, we evaluate MFQ mainly for three different multicast bandwidth allocation schemes ....

....will be changed. For Rt3 and Rt5 , when they receive ( G) Prune, they just remove the MCT as well as each group entry. For Rt7 , since the outgoing interface will be changed, like Rt2 , it recreates MCT for new (S; G) entry. 5. PERFORMANCE EVALUATION We implemented our proposal in ns simulator [25] and we evaluate its performance using several metrics. We generate 100 network topologies of 1000 nodes with di erent connectivities values using the Brite tool [23] We varied the group size from 5 to 200. For each multicast group, we use an uniform distribution to generate the location of the ....

....control in place, more flows complete in comparison to the no admission control case. Additionally flows complete on average faster, and a higher proportion achieve a consistent minimum goodput (the value of 10 packets per second was used) over their lifetime. 3.4. 1 The Network Simulator, NSv2 NS (NETWORK SIMULATOR V2) NSv2] is a discrete event simulator, built specifically to simulate Internet protocols. It simulates at a per packet level, using a C back end to manage common, per packet operations, and an OTcl [Wetherall00] front end to construct the simulations and initial event ....

....if all flows do not share any common bottlenecks and each is grouped separately, which would not occur often. This is due to the locality of server requests, as well as Internet topology power law characteristics. 4 Performance Analysis We have implemented FlowMate in the ns 2 network simulator [24]. In this section, we conduct several experiments to evaluate its performance. We investigate FlowMate robustness under heavy background traffic using Pareto sources or self similar traces, and with various foreground traffic models, including FTP, Telnet and HTTP. We also study the effect of ....

....a network topology, configuring it, and defining modifications for simulation time. The application produces the code to run the simulation, runs the simulation, retrieves the results, and presents them to the user. The main simulation work is done by the VINT Project s network simulator (ns) [3] version 2.1b5a, with a modified version of the DiffServ patches [4] The ns network simulator has an extensible simulation engine implemented in C that uses MIT s Object Tool Command Language,OTcl (an object oriented version of Tcl, the Tool Command Language [5] as the command and ....

....While working, the active policies make the current status of their activity available through management quality of service parameters that provide an indication of how well they are performing their task. The results presented in this paper were obtained with VINT project s network simulator [3], with a modified version of DiffServ patches [4] for the 15 node network of [7] The results show that the use of active policies improves the service offered to users, by constantly adapting to the network state, and helping to fulfill service level agreements with minimum costs to the service ....
