Abstract
A method is disclosed for the collection of performance metrics by establishing service operations administration and maintenance (OAM) sessions between an actuator and a plurality of reflectors in a communication network. Test packets from an actuator simultaneously reach a plurality of reflectors along a test path. Each single test packet results into a plurality of test results, one per reflector, with quasi-synchronous performance metrics to sectionalize a network and more efficiently isolate fault or performance problems without the need for additional test packets to isolate the issue. Another method is disclosed wherein an actuator generates and transmits a plurality of simultaneous test packets, one per NID device, resulting into a plurality of test results, one per reflector, with quasi-synchronous performance metrics to sectionalize a network and more efficiently isolate fault or performance problems without the need for additional test packets to isolate the issue.
