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 BART project.

Set A 100msec Packet Inter-Arrival Time


The following section discusses the difference between automatically allowing the interface to detect the line speed and explicitly setting the line speed of an interface for 100msec packet inter-arrival time for Set A.

Again, as when the inter-arrival time was set to 125usec, 500usec, 1msec and 50ms, the results show that explicitly setting the line speed on the receiving interface is desired as the time stamps are concentrated and no far outliers result.

Figure 19: Explicit 10Mbit/sec
Figure 20: Automatic 100Mbit/sec
Figure 21: Explicit 100Mbit/sec

The tables below are consistant with all previous results for 125usec, 500usec, 1msec and 50msec results. When the line speed on the interface is configured to be automatically detected, the time stamp varience and standard deviation are very large.
