Experimental analysis of propagation properties implementing the path-based measurement

Abstract

In this paper, we will show the experimental analysis of network load propagation properties of Internet paths using our IP performance active measurement method. This method sends ICMP T1MESTAMP messages and receives reply messages to and from each node along the path. After collecting and analyzing the delay fluctuations and loss occurrences, we extracted following results. First, delays are classified two types, burst-type delays and cyclic delays. Second, burst-type delays caused by loads on intermediate routers were propagated to each node throughout the path. Third, cyclic delays were peculiar to each node and had time intervals of 30 or 60 seconds. Fourth, forward trip time included cyclic delays and backward trip time included burst-type delays. Finally, scattered losses occurred along paths through one of the providers.
