Methods, systems, and apparatus for generating a delay profile for different priority classifications. In one aspect, multiple latency probes are transmitted by a source node to a target network node. Each latency probe has a different priority code. A response to each of the transmitted latency probes is received by the source node from the target network node. Based on the received responses, a delay profile for the target network node is generated by the source node. The delay profile provides multiple network latency measurements for packets transmitted to the target network node with the different priority codes. A user interface of a display is updated to visually present at least a portion of the delay profile.

In accordance with a non-limiting example, a system and method minimizes collisions between transmitted connectivity fault management (CFM) packets. Maintenance association endpoints are formed from a plurality of network switch elements to form a maintenance association. The clocks between each network switch element within the maintenance association are synchronized. A unique transmission window is assigned to each maintenance association endpoint as part of the maintenance association. A respective CFM packet is transmitted as a continuity check message (CCM) within the unique transmission window.
