Network Performance Monitoring for Applications Using EXPAND

In English As computing becomes more interactive and as networked applications need special system support, it
has become increasingly important to manage network resources. An important part of the management
lies within monitoring network behaviour. It is important for many applications to be able to estimate
system performance in order to select appropriate encoding schemes, adaptation, buffering sizes etc. This
paper discusses monitoring within wired and wireless networks and the type of monitoring information
needed to support different applications. We suggest a hybrid active/passive monitoring approach with a
dynamic time window mechanism and interchangeable filters to extract requested information. The paper
also shows our initial experimental results and presents our conclusions.
