Patent ID: 8139475

Claim:
A method of fault and performance recovery in a communication network comprising a set of network apparatuses, said network comprising a plurality of sites connected by means of connections having a given topology and adopting a given routing policy, the network having associated therewith at least one database maintaining information regarding said network apparatuses, comprising the steps of: executing at least one set of performance tests, wherein said at least one set of performance tests is created automatically by exploiting the information available on the topology of the connections between the various sites and by accessing said at least one database; optimizing said set of performance tests by automatically configuring a minimum number of performance tests to guarantee performance monitoring of said network with coverage of all the communication stretches therein by configuring only one measurement for each pair of sites connected in said topology; analysing the results of said at least one set of performance tests to detect possible fault and performance impairment conditions of said network; modifying said routing policy to compensate for a fault and performance impairment condition in the presence of a fault and performance impairment condition detected in said network; and distributing the performance tests to be performed at said sites in said network by generating for each apparatus involved a value representative of the performance tests to be entrusted to said apparatus.
