[ndnSIM] Implementing Router Queues in ndnSIM

[Spyridon (Spyros) Mastorakis]

Hi,

I am not sure to which “buffer” you are referring to, but an easy way to do that (so that you have easy access too) is to create a custom application that you will install on all the routers. This app will receive Interests, record them and then simply further forward them. Once the data packet is received, you can delete the Interest from your queue. 

Another way to do that (with less flexible access probably) is to hack NFD directly and add an std::vector object or something as an attribute to the Forwarder class:

https://github.com/named-data-ndnSIM/NFD/blob/NFD-0.6.0-ndnSIM/daemon/fw/forwarder.cpp <https://github.com/named-data-ndnSIM/NFD/blob/NFD-0.6.0-ndnSIM/daemon/fw/forwarder.cpp>
https://github.com/named-data-ndnSIM/NFD/blob/NFD-0.6.0-ndnSIM/daemon/fw/forwarder.hpp <https://github.com/named-data-ndnSIM/NFD/blob/NFD-0.6.0-ndnSIM/daemon/fw/forwarder.hpp>

Hope that this helps,
