Class of service probe

A telecommunications device, comprising:

• a communications interface that communicatively couples the telecommunications device with a plurality of network nodes;
• a memory structure storing machine executable instructions;
• and
• one or more processors that execute the machine executable instructions and perform operations including:
• transmitting, to a target network node, a plurality of latency probes each having a different priority code;
• receiving, from the target network node, a response to each of the transmitted latency probes;
• generating a delay profile for the target network node based on the received responses, wherein the delay profile provides multiple network latency measurements for packets transmitted to the target network node with the different priority codes;
• and
• updating a user interface of a display to visually present at least a portion of the delay profile.

A system, comprising:

• a plurality of network nodes, each network node configured to respond to latency probes;
• and
• a source node configured to:
• transmit, to a target network node among the plurality of network nodes, a plurality of latency probes each having a different priority code;
• receive, from the target network node, a response to each of the transmitted latency probes;
• generate a delay profile for the target network node based on the received responses, wherein the delay profile provides multiple network latency measurements for packets transmitted to the target network node with the different priority codes;
• and
• update a user interface of a display to visually present at least a portion of the delay profile.
