Hi Saranya & Mohamad,

 

I have a question about Trace Route (found under Call Analytics Overview --> Network --> (sub-header) Trace Route), and its relation to Average/Max Round Trip Time (found on same page, but under sub-headings Inbound Network & Outbound Network).

 

Scenario:  Under the Heading 'Outbound Network' - I am looking at a call with Average RTT = 150ms and Max RTT = 159ms.

Meanwhile, Under the Heading 'Trace Route' - I am seeing the maximum Round Trip Time listed for any of the several hops is 80ms.

My question is:  Can you please define the source/origin of the Round Trip Time entries in the Trace Route table?

Is it always the endpoint (so - with each incremental hop, the RTT is inclusive of the hop(s) before it)?

Or is it only representing the time between it and the previous hop?

 

I am suspecting the former, but want to confirm.

 

Thank you.

    So, This is a bit unique and we are in fact tweaking the way this feature works in ACA. As soon as your traceroute hits the first ingress point of the "Microsoft Network", the final hop starts replying not that hop. Other hops, it will be the intervening hop itself replying, but once it reaches our side, it is the final hop replying.

      Thanks Aaron.

      The 'unique' workings are still a little fuzzy, but good to know it is still in development.  I will be keeping an eye on the evolution.

      Cheers ~
