PathCrawler: Automatic harvesting web infra-structure [PDF]

NOMS 2008 - 2008 IEEE Network Operations and Management Symposium, 2008
As network topologies have grown in size and complexity, it is becoming a daunting task for network administrators to keep track the capacity dimensioning of newly installed web-servers within a single or multiple providers. In fact, monitor capacity dimensioning is not a trivial activity since network state changes rather frequently, in particular, in
