Network Performance Monitoring for Applications Using EXPAND

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. (Less)
