[ndnSIM] A problem about the protocol header in packets

[刘总真]

Hi Alex,


Thank you very much for your reply! In my scenario, there are several NDN nodes, two AP nodes and one mobile Sta node. The Sta node handover between the two AP nodes. Firstly I use ndn::GlobleRoutingHelper to calculate the routes before simulation. When the Sta node connect to the first AP and to the corresponding NDN node with TCP connection. All are right.  But when the Sta node walks and connects to the second AP node and fetch contents, in the pcap file from the Sta node, the type of the packets is LLC  , instead TCP. In addition, I find if I use  ndn::GlobleRoutingHelper to calculate the routes, the hop of shortest path between two NDN nodes, the algorithm also consider the wifi path, not just the p2p path.


Looking forward to your response. Thank you very much for your help!
