Overview

The stochastic graph process solver (GROOVER) is a Monte Carlo intergation tool developed at the Dipartimento di Ingegneria e Scienza dell'Informazione (DISI) of the University of Trento; its target is to analyze Overlay Content Distribution Systems.

GROOVER explores the state space of a Markov chain whose states are represented by graphs: each graph contains the nodes that have been reached by the content and the edges used to distribute it.

GROOVER comes in two flavors:

  • analysis of non real-time distribution process, such as File Distribution;
  • analysis of real-time distribution process, such as Overlay Streaming.

In both cases the tool consider tree- and mesh-based architectures and can be easily configured to obtain different scenarios: by properly adjusting the input parameters it is possible to obtain networks with 103-106 nodes, with different constraints on minimum and maximum outdegree.
