As part of a broader organisational restructure, data networking research at Swinburne University of Technology has moved from the Centre for Advanced Internet Architecture (CAIA) to the Internet For Things (I4T) Research Lab.

Although CAIA no longer exists, this website reflects CAIA's activities and outputs between March 2002 and February 2017, and is being maintained as a service to the broader data networking research community.

This page is part of the GENIUS project.

Maps and Map Changes

The following is an analysis on the effects of map changes and how they can be identified in the result data. To separate the individual maps for visual aid, null histograms were added into the data results.

Map Changes

The following graphs indicate where map changes occur in an inter-arrival and packet length graph from the server to a client. The slight variation in the graph of Figure 13 (IH15 and IH24) corresponds to that of a map change. This is not, however, as obvious as in Figure 14 which clearly shows how map changes affect the packet length data results. The end of each map is indicated by a concentration of same-size packets (larger spike). These spikes were removed from subsequent graphs to show the map details more clearly.

Figures 15 to 20 show the packet length characteristics from the server to the clients (three client game) of each map the Quake 3 server cycles through. We can clearly see that the maps have a consistent individual histogram shape and a large number of small-length packets that are sent before each map is terminated. Figure 20 shows the same five maps together during a game (click on Figure 20 to see a close-up of the distributions with the tallest peaks removed).
