T. Qiu, E. Chan, G. Chen

Methods for Improving Resilience in Communication Networks and P2P Overlays

M. Brinkmeier, M. Fischer, S. Grau, G. Schäfer, T. Strufe
2009 PIK - Praxis der Informationsverarbeitung und Kommunikation  
In this article, we present a survey of strategies to improve resilience in communication networks as well as in P2P overlay networks.  ...  Furthermore, our intention is to point out differences and similarities in the resilience-enhancing measures for both types of networks.  ...  This notion of congestion corresponds to the notion of congestion in communication networks, in the sense, that an edge with a high congestion, tends to be used by a higher number of packets, than edges  ...

Fighting Erosion in Dynamic Large-Scale Overlay Networks

R. Baldoni, S. Bonomi, L. Querzoni, A. Rippa, S. Tucci Piergiovanni, A. Virgillito
2007 Advanced Information Networking and Applications  
Overlay management protocols have been introduced to guarantee overlay network connectivity in dynamic largescale peer-to-peer systems.  ...  This mechanism is shown to be effective in reducing the erosion of an overlay network exposed to continuous churn and to quickly recover its connectivity during stability periods.  ...  In [2] the protocol is introduced in a synchronous environment where the notion of round is clearly defined.  ...

Peer the peers

Matthias Wählisch, Thomas C. Schmidt
2009 Proceedings of the 5th international student workshop on Emerging networking experiments and technologies - Co-Next Student Workshop '09  
Regrettably, overlay traffic is not optimal with respect to native connections and peering agreements, but may decrease network quality at end users at increased transit costs.  ...  P2P networks enable end users to establish services relying neither on a dedicated infrastructure nor on an ISP deployment of enhanced services at the network layer.  ...  The main inter-AS connections, though, do not change during the lifetime of an overlay peer in typical P2P scenarios.  ...
