Centre closure

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.

Single Client Traffic Results

The following section discusses individual server to client and client to server flows.

Packet Inter-Arrival Time
As seen in Figure 1, most of the traffic sent from the client to the server in a three player game peaks at approximately every 16ms. Figure 2 is an example of a four player game where this pattern does not happen, rather there is usually one main peak occuring at approximately 33ms.

In Figure 3A and Figure 3B we can see the inter-arrival graphs produced by data from the server to a client during a three client game in 2D and 3D respectively. The 3D graph clearly shows that 50ms peak intervals are consistent over most of the data set. Figure 4A and Figure 4B show the same characteristics occuring in the four client game. The multiples of 50ms found in this data is unexpected and could be due to slow clients and Internet delays resulting in the server updating at a slower rate.

From Figure 5A and its corresponding 3D graph in Figure 5B, we can see when the server is taking approximately one to three minutes to send 2000 packets to the client. These packets are sent with an inter-arrival time of 50ms. We can also see that taking approximately more than three minutes to send 2000 packets results in an inter-arrival time of mainly 100ms peaks.

Packet Length
As we can see from Figure 7A, the mean of packets sent from the client to the server are approximately 73 bytes long with a distinct 'M' shape. Figure 7B shows the same set of data in 3D, to illustrate that some histograms peak highly on the left side of the 'M' due to map change.

Figure 8 shows that packet length distribution is greater from the server to the client than from the client to the server, with a packet length mean being 155 bytes (click on Figure 8 to see a close-up of the distribution with the tallest peak removed).
