[ndnSIM] [EXT] [ndnSim] How to change the default values from NFD configuration fil

[Leandro Alves]

Hi Junxiao,

I’m new to ndnSIM, so, maybe this is a dumb question, but how and when call ns3::ndn::NetDeviceTransport constructor. And I need to call the constructor for every node that my scenario has?

Hi Leandro

NFD's UDP transport is not compiled into ndnSIM:
https://github.com/named-data-ndnSIM/ndnSIM/blob/28da73c868ad7444dba7a754fb77a41f6ca7cb07/wscript#L136
Consequently, the face_system.udp section is unrecognized.

You can set the link type when calling ns3::ndn::NetDeviceTransport constructor.

Yours, Junxiao

Hello all,

I’m currently trying to make a custom forwarding strategy for vehicular adhoc network and I started to using multicast strategy but all link types are point-to-point by default. So I change the current configuration at ndn-l3-protocol.cpp<https://github.com/named-data-ndnSIM/ndnSIM/blob/master/model/ndn-l3-protocol.cpp#L117> in section face_system to support multicast adhoc.. However, when I compile my scenario I get the following error: unrecognized option face_system.udp.

So, my configuration looks like this:
/*rest of the code*/
"\n"
"face_system\n"
"{\n"
"  udp\n"
"  {\n"
"    mcast_ad_hoc yes\n"
"  }\n"
"}\n"
"\n"
/*rest of the code*/

I’m doing something wrong or I’m missing some important step?

Thanks in advance,
Leandro Alves
