Abstract
A system for fault and performance recovery in a communication network includes a set of network apparatuses as well as a plurality of sites connected by means of connections having a given topology. The network also includes routers for implementing given routing policies and has associated therewith at least one database maintaining information regarding the network apparatuses. The system includes test modules for executing performance tests created automatically by exploiting the information available on the topology of the connections between the various sites and by accessing the database in question. The test modules are configured for analysing the results of the performance tests to detect possible fault and performance impairment conditions of the network. In the presence of a fault and performance impairment condition detected in the network, the routers modify the routing policy to compensate for the fault and performance impairment condition.
