[ndnSIM] Calculate Hit Rate from Spesific Nodes in NFD Content Store

[mdparamartha95 at students.itb.ac.id]

Hi Junxiao, 

Finally i decided just print hit rate generated by each router from log file. 
And it's worked as you said for each router counters. 

Thank you so much for the information 

Its very helpful. 

Best Regards, 
Adi Paramartha

Hi Junxiao, 

After 1 day trying to understand the forwarder in ndnSIM, but i couldnt get it. 

I'm sorry I'm confuse about implement the Forwarder codes to count the hit ratio, 

Where should I implement it ? 
Should i call it like the old cs-tracer ? 
Or put it into cs.cpp ? 

Could you please give some example ? 
Thank you so much, 

Best Regards,

Hi Adi 

NFD already has CS hit/miss counters: 

1. Get a hold of Forwarder instance. 
2. Read the counter with forwarder.getCounters().nCsHits and forwarder.getCounters().nCsMisses. 

There’s no need to modify any callbacks. 

Yours, Junxiao

I had a problem to calculate the hit rate from the spesific node in NFD Content Store, 

For example, I had installed cs-policy-lru in 5 nodes. 

However, I just want to trace the performance of nodes 1 instead of nodes 2,3,4 or 5 . 

As long as my experience, in cs.cpp using a callback function and add some increment if hitcallback or misscallback is called. 

But results show that the increment works with all nodes, and give me entire nodes hit/miss rate. Not hit/miss rate for specific nodes. 

How can I calculate the hit/miss rate from specific nodes?
