Abstract
This paper is motivated by the observation that gathering and analyzing the behavior and performance of applications leads to more informed decisions by network managers.In particular, application management can be used to improve network traffic engineering tasks. In this paper, we investigated the existing/potential network monitoring frameworks and showed how they can be effectively used to extract application-level information from network applications, running environments and the communication links. We also identified important application-level information for network management and traffic engineering, which couldn’t be easily supported by the simple network-level monitoring information.
