METHOD AND APPARATUS FOR CONTROL PLANE TO CONFIGURE MONITORING OF DIFFERENTIATED SERVICE CODE POINT (DSCP) AND EXPLICIT CONGESTION NOTIFICATION (ECN)

摘要

A method is executed by a network device implementing a control-client to configure 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. Multiple DSCP and ECN are tested using the single test session. The method includes receiving a server greeting message from a server including characteristics of the session-reflector, determining whether the session-reflector supports use of multiple DSCP in the single test session, setting a set-up- response message to indicate DSCP and ECN testing, and determining whether the session- reflector supports DSCP and ECN monitoring. The method further includes adding an indicator of DSCP and ECN monitoring in the set-up-response message, in response to a determination that the session-reflector supports DSCP and ECN monitoring, and sending the setup-response message to the server.
