The complexity of network management is widely recognized as one of the biggest challenges facing the Internet today. Network operators are under tremendous pressure to make their networks highly reliable to avoid service disruptions. Yet, operators often need to change the network to upgrade faulty equipment, deploy new services, and install new routers. Unfortunately, changes cause disruptions, forcing a trade-off between the benefit of the change and the disruption it will cause. We argue that many network-management problems stem from the same root causes - the need to maintain consistency between the physical and logical configuration of the routers and the static coupling of router state and functionality to specific router instances. Hence, we propose two new network-management primitives where (. Sleuthkit. BACS 371. Computer Forensics. Introduction.
