Abstract
The present invention relates to method and arrangements to measure connectivity between Two Way Active Measurement Protocol TWAMP entities comprising a session-server (15) and session-reflectors (16-23) in a communication network. The method comprises steps like: Dividing in the session-server (15), the session-reflectors (16-23) into at least one defined group (11-14) of session-reflectors (16-17,18-9,20-21,22-23); Transmitting a test session (1;1-4) from the session-server (15) to the session-reflectors (16-7;16-23) by using Source Specific Multicasting, said test session comprising at least one test packet (1a-1c;1a-4c) 1 being destined to at least one session-reflector (16-17;16-23) in at least one defined group (11;11-14); Replying to the at least one test packet (1a-1c;1a-4c) by the at least one session-reflector (16-17;16-23).
