Virtual Delivery Trees Evaluation Results

The artifacts represent evaluation results of real world networks having more than 40 nodes from Network Topology Zoo. The applied topologies are listed in following table, sorted in descending order by diameter (d) and nodal degree fluctuation (σ^2)).

Strategy Results: Visualization of the test results for each topology. Best Strategies: Highlighting of the best strategies across all topologies. Therein, the "Raw Data" comprise the configuration of or simulation experiments and the simulation results. Each line stands for a single simulation run. "Strategy Results" and "Best Strategies" accompany the results presented in the paper. Result plots in the paper are excerpts from the plots in this repository. See below for further details. Raw Data Both, the configuration of a run and its results correspond to one line within a CSV file in subfolder ./raw. Each file comprises the results of a replication. raw ├── results_0.csv ├── results_1.csv ├── ... └── results_9.csv The raw data of a CSV file is structured as follows. Column Description topo Topology name. peers Number of nodes. edges Number of links. p_publishers Proportion of nodes acting as publisher (15% - 45%). p_subscriber Proportion of nodes acting as subscriber (15% - 45%). n_rules Number of allowed rules per switch. distances Flag for consideration of geographical distances (currently not used). strategy Applied virtual tree strategy. distribution Distribution method for client (uniform, distant, nearby) n_cluster Number of simulated clusters within the topology. p_change Churn rate of clients (
