On Selfish Routing in Internet-Like Environments

by Lili Qiu, Yang Richard Yang, Yin Zhang, Scott Shenker , 2004
"... A recent trend in routing research is to avoid inefficiencies in network-level routing by allowing hosts to either choose routes themselves (e.g., source routing) or use overlay routing networks (e.g., Detour or RON). Such approaches result in selfish routing, because routing decisions are no longe ..."

to investigate the performance of selfish routing in Internet-like environments, using realistic topologies and traffic demands in our simulations. We show that in contrast to theoretical worst cases, selfish routing achieves close to optimal average latency in such environments. However, such performance

Scalable Application Layer Multicast

by Suman Banerjee, Bobby Bhattacharjee, Christopher Kommareddy , 2002
"... We describe a new scalable application-layer multicast protocol, specifically designed for low-bandwidth, data streaming applications with large receiver sets. Our scheme is based upon a hierarchical clustering of the application-layer multicast peers and can support a number of different data deliv ..."

delivery trees with desirable properties. We present extensive simulations of both our protocol and the Narada application-layer multicast protocol over Internet-like topologies. Our results show that for groups of size 32 or more, our protocol has lower link stress (by about 25%), improved or similar

Compact routing on Internet-like graphs

by Dmitri Krioukov, Kevin Fall - In Proc. IEEE INFOCOM , 2004
"... Abstract — The Thorup-Zwick (TZ) compact routing scheme is the first generic stretch-3 routing scheme delivering a nearly optimal per-node memory upper bound. Using both direct analysis and simulation, we derive the stretch distribution of this routing scheme on Internet-like interdomain topologies. ..."

End-to-End Loss Probabilities in Different Internet-like Networks with a Given Average Hop Count

by Maurizio Longo, Fabio Postiglione
"... Abstract:- Realistic networks generators are necessary for simulation and performance evaluation of data communication systems. Such an aspect has driven the collection and the analysis of data on the Internet large-scale structure. The evidence of a power-law behavior of real networks has stimulate ..."
Abstract - Add to MetaCart
stimulated the introduction of new procedures to generate Internet-like topologies. Assuming a simple loss model for the links, this paper analyses how the prediction of the loss probabilities during communications obtained by simulation can be influenced by the adoption of a specific topological model

BRITE: An approach to universal topology generation,”

by Alberto Medina , Anukool Lakhina , Ibrahim Matta , John Byers - in Proceedings of the IEEE Ninth International Symposium on Modeling, Analysis and Simulation of Computer and Telecommunication Systems, , 2001
"... Abstract Effective engineering of the Internet is predicated upon a detailed understanding of issues such as the large-scale structure of its underlying physical topology, the manner in which it evolves over time, and the way in which its constituent components contribute to its overall function. U ..."

Internet topology modeler based on map sampling

by Damien Magoni, Jean-jacques Pansiot - In Proceedings of ISCC’02, IEEE Symposium on Computers and Communications , 2002
"... Creating a network topology is the first step in building a scenario for a network protocol simulation. The simulation results usually depend on the topology layout, especially for routing and multicasting protocols. Therefore the topology used should be generated with the highest possible accuracy. ..."
Abstract - Cited by 28 (6 self) - Add to MetaCart
. In particular, protocols designed for the Internet should be simulated over Internet-like topologies. Many topology generators currently exist but the recent discovery of power laws in the Internet has brought new constraints upon the generated topologies. We introduce a flexible novel way to create Internet-like
