A formal framework for the performance analysis of P2P networks protocols

A. Spognardi, R. Di Pietro
2006 Proceedings 20th IEEE International Parallel & Distributed Processing Symposium  
In this paper we introduce a versatile model for the analysis of P2P protocols. We employ this model to formally prove which is the average lookup length for two sample protocols: BaRT and Koorde.  ...  Despite the proposal of several protocols for P2P networks, sometimes there is a lack of a formal demonstration of their performance: experimental simulations are the most used method to evaluate their  ...  The authors are grateful to professor Luigi V. Mancini and the anonymous reviewers for providing useful suggestions and comments.  ...

ALVIC versus the Internet: Redesigning a Networked Virtual Environment Architecture

Peter Quax, Jeroen Dierckx, Bart Cornelissen, Wim Lamotte
2008 International Journal of Computer Games Technology  
The Architecture for Large-Scale Virtual Interactive Communities (ALVICs) was originally developed to serve as a generic framework to deploy networked virtual environment applications on the Internet.  ...  While it has been shown to effectively scale to the numbers originally put forward, our findings have shown that, on a real-life network, such as the Internet, several drawbacks will not be overcome in  ...  The authors are grateful to the partners involved in the IBBT Teleon project, as well as the members of the NVE research group at EDM.  ...

SoK: Understanding BFT Consensus in the Age of Blockchains [article]

Gang Wang
2021 IACR Cryptology ePrint Archive  
Blockchain as an enabler to current Internet infrastructure has provided many unique features and revolutionized current distributed systems into a new era.  ...  For each representative protocol, we conduct an in-depth discussion of its most important architectural building blocks as well as the key techniques they used.  ...  Thus, it is difficult to be adopted into large-scale consensus protocols, and current popular blockchain systems prefer peer-to-peer diffusion. b) Peer-to-Peer Diffusion: P2P networks are distributed systems  ...
