Method and apparatus for data plane to monitor differentiated services code point (DSCP) and explicit congestion notification (ECN)

Abstract:

A method is executed by a network device implementing a session-sender to perform a test to determine whether differentiated services code point (DSCP) and explicit congestion notification (ECN) are modified in a single test session in a forward direction and a reverse direction between the session-sender and a session-reflector, where multiple DSCP and ECN are tested using the single test session. The method includes determining a first initial forward DSCP and ECN, generating a first test packet including the first initial forward DSCP and ECN, and sending the first test packet to the session-reflector in the single test session. The method further includes determining a second initial forward DSCP and ECN, generating a second test packet including the second initial forward DSCP and ECN, and sending the second test packet to the session-reflector in the single test session.
