METHOD FOR PERFORMING TWAMP

The present invention provides an apparatus comprising a network device. The network device includes a Internet Protocol, IP, performance measurement, PM, Sender controller module to distinguish different TWAMP E2E paths between the Sender and Reflector by sequence of IP addresses as learned from TWAMP path discovery and a Two-Way Active Measurement Protocol, TWAMP, module, coupled to the IP PM controller module. The TWAMP module includes a TWAMP packet selection content module to determine, for each TWAMP test session, the content to include in the TWAMP test request packets and a TWAMP communication module, coupled to the TWAMP packet selection content module, to perform the TWAMP path discovery for the TWAMP test sessions configured for TWAMP path discovery, and to collect TWAMP PMs for each of the TWAMP test sessions.
