[ndnSIM] Addtional metadata in Interest and data packet

[황인찬]

Dear NDN Sim users,



I have been trying to add an additional property to an Interest packet.

In NDN-cxx, there is Interest.cpp file that defines Interest encoding in
Interest::wireEncode(EncodingImpl<TAG>& encoder)



// Interest ::= INTEREST-TYPE TLV-LENGTH

  //                Name

  //                Selectors?

  //                Nonce

  //                InterestLifetime?

  //                Link?

  //                SelectedDelegation?



  //                ProducerUid? à ....................... I added it.



// (reverse encoding)



There is also a decoding scheme for it, Interest::wireDecode(const Block&
wire) in the file.



Although I added additional variables and its getter and setters to the
Interest packet,

There is an error "Requested decoding of ControlResponse, but Block is of
different type"

when I run it with after I add //totalLength +=
getProducerUid().wireEncode(encoder); for wireEncode

//m_ProducerUid.wireDecode(m_wire.get(tlv::Name)); for wireDecode.



I am now trying to match block types equal, But I am stuck. Does anyone of
you know about adding a new property to the Interest and data packet?

Any comment will help


Here is the current code I have been working on is in "
https://github.com/NDNUtils/NDNSIM"



Best wishes,
