[ndnSIM] ndnSIM Digest, Vol 76, Issue 16 How to delete a CS entry in a router

Thu Mar 21 05:39:08 PDT 2019

Hi Mengxue,

actually, there's a function to erase the data stored in the content store,

however, it depends on which content store implementation you had used?

There's OldContentStore and NFD Content Store,

You can look forward to evictEntries() function in ndnSIM.

Best Regards,
Adi Paramartha

Hi all?

    Now, I have already seen the entries that stored in a router's contentstore?and I want to delete some data packets and special entries from the contentstore.

How to code it? Is there any way to do it?

    Thanks in advance.

Best regards,
Xue Meng

Hello everyone,

Actually, I am working on a scenario simulation and I need your help.
I want to create variables to use them as counters for these metrics:

   - InInterests
   - OutInterests
   - InData
   - OutData
   - InNacks
   - OutNacks
   - SatisfiedInterests
   - TimedOutInterests

I need these variables in my simulation. I want to use them to make some
calculations and then decides of the action to take.

I tried to use "ndn-l3-rate-tracer.cpp" file but I don't know how.
If you have any suggestions, please help me.

Thank you in advance.
With my respects,
Ahmed.

Hello Safa;

Thank you so much for your reply even though this is not what I meant.
What I want to do is:

- Create a variable for each metric (initialised to 0).
- Variables increments throughout the simulation process.
- Nodes will use these created variables to take actions.

In other words, I need these metrics to use them as parameters in my
simulation and not just results (text file).

Best regards,
Ahmed.

Hi,

probably something like the forwarder counters could work:

https://github.com/named-data-ndnSIM/NFD/blob/NFD-0.6.5-ndnSIM/daemon/fw/forwarder.hpp#L293 <https://github.com/named-data-ndnSIM/NFD/blob/NFD-0.6.5-ndnSIM/daemon/fw/forwarder.hpp#L293>

Thanks,
