Hi,

Although this document is a generic requirement for tunnel tracing, I find many protocol specific requirements that are not actually a requirement, rather they are suggesting a specific solution.

For example:

"The protocol elicits a series of traceResponse messages."
"Each traceResponse message represents a hop that connects the head-end of the traced path to the tail-end of the traced path"  
"Each traceProbe message elicits exactly one traceResponse message."
"UDP carries traceProbe and traceResponse messages to their destinations."


Thanks,
