Yes Ashlesh, it was redirected to ndn-interest and not answered.  However,
I have very similar (and kind of rookie) question to the one asked in that

Repeating the question from previous mail and adding some of my question

>* Is there any way (on current NFD implementation) that one can list the Measurements Table entries using something as nfd-status? Or just accessing via code methods get/setEntry ?
*> >* I also have questions about how it is used by the forwarding
strategies. On NFD-dev guide it states that the strategies use the
table to store arbitrary information (can be delay, jitter, RTT,
etc.), but on http://named-data.net/doc/NFD/current/overview.html
<http://named-data.net/doc/NFD/current/overview.html>> it says that
the strategies stores past performance results. How "past" is that?
How often does strategies update this table?
*> >* I am guessing that what you would like to store varies from each
forwarding strategy, but is there any common frequency of updates that
the strategies use to input entries on the table (e.g. every
successful interest-data retrieval)?*

I see a name-tree structure here.    http://irl.cs.ucla.edu/~cawka/
Measurement table basically allows accessing/storing pit,fib entries using
get(), findexactmatch(), findlongestprefixmatch() functions.

Additionally, is it possible to store Content store hit time/ hit rate
(assuming I calculate it somehow) in the measurement table? All I am trying
to figure out is, what are the parameters which are already stored in
measurement table and how feasible it is to add new parameters to that

My understanding is, the existing tree implementation does not support
adding a new <parameter, value> pair to measurement table. Am I correct?

If above storing <parameter, value> pair concept is not feasible, do I need
to create a new data structure to store measurement parameters like
hit/miss rate, latency etc?

Thank you for long read and your valuable time.
