Abstract
A fault manifested in a network between two network nodes is investigated by selecting highest probability failure modes of resources which form network pathways between the two nodes, and probing the network to establish whether any of the highest probability failure modes are the cause of the fault. If not then a group of lower probability failure modes are selected and the network is probed once again to establish whether any of the lower probability failure modes are the cause of the fault. This process may be repeated until the fault is diagnosed. Resources are defined at the discretion of an administrator, and so may be clustered groups of computing entities and network links, or defined at a level of particularity such that functional elements within a computing entity such as a network card and a driver are defined as resources.
