Accurate bandwidth measurement is essential for network
management, monitoring, and planning. Various active probing-based
strategies and tools are have been developed for estimating available
bandwidth. However, the test result of each tool could be different according
to the strategies and tools even in the same network environment.
The purpose of this paper is to give comprehensive information to users
with interpretive comparison and performance test. The comparison and
test with regard to measurement efficiency, and traffic load of probing
packets. including IGI/PTR, pathload, pathChirp, spruce, and Iperf, are
performed in dynamic network environments.
