<div>Hi sir :<br> I find out that my last
email is incomplete in maillist, so I finish it and send
again. </div>
<div> I am trying to add hop information in
Interest recently on <strong>ndnSIM 2.2</strong>. Here is my code.</div>
<div>1). I add a private member variable which is named
hop in ndnSIM/ndn-cxx/src/interest.h </div>
<div>
private:</div>
<div>
Name m_name;</div>
<div>
......</div>
<div>
mutable Block m_wire;</div>
<div>
<span style="FONT-SIZE: 16pt"><strong><span style="FONT-SIZE: 14pt"><span style="FONT-SIZE: 16pt"><span style="FONT-SIZE: 16pt">int
hop;</span></span></span></strong> </span>
// a new private member
variable </div>
<div> </div>
<div>2). I increace the value of hop in the
nfd::Forwarder::onOutgoingInterest(shared_ptr<pit::Entry> pitEntry,
Face& outFace,<span style="COLOR: rgb(96,64,32)" class="keywordtype">bool </span>wantNewNonce),so as to caculate the hop
.</div>
<div> </div>
<div style="FONT-SIZE: 16pt"> <span style="FONT-SIZE: 10.5pt"><strong><span style="FONT-SIZE: 16pt"> int
tmpHop=interest->getHop();</span></strong></span></div>
<div style="FONT-SIZE: 10.5pt"><strong><span style="FONT-SIZE: 16pt">
tmpHop++;</span></strong></div>
<div style="FONT-SIZE: 16pt"><span style="FONT-SIZE: 10.5pt"><span style="FONT-SIZE: 16pt"><strong><span style="FONT-SIZE: 16pt">
interest->setHop(tmpHop);</span></strong> </span> </span>
</div>
<div align="center"> </div>
<div align="left">Here is my problem,It seems that the hop value is always 0 no
matter how many nodes it is forwarded.How to solve the problem? I know there is
a <span style="WIDOWS: 2; TEXT-TRANSFORM: none; BACKGROUND-COLOR: rgb(232,232,232); FONT-STYLE: normal; TEXT-INDENT: 0px; DISPLAY: inline !important; FONT-FAMILY: 'Lucida Grande', Verdana, Geneva, Arial, sans-serif; WHITE-SPACE: normal; ORPHANS: 2; FLOAT: none; LETTER-SPACING: normal; COLOR: rgb(50,50,50); FONT-SIZE: 13px; FONT-WEIGHT: bold; WORD-SPACING: 0px; font-variant-ligatures: normal; font-variant-caps: normal; -webkit-text-stroke-width: 0px">ns3::ndn::FwHopCountTag
</span>a to caculate the hop in <span style="WIDOWS: 2; TEXT-TRANSFORM: none; BACKGROUND-COLOR: rgb(232,232,232); FONT-STYLE: normal; TEXT-INDENT: 0px; DISPLAY: inline !important; FONT-FAMILY: 'Lucida Grande', Verdana, Geneva, Arial, sans-serif; WHITE-SPACE: normal; ORPHANS: 2; FLOAT: none; LETTER-SPACING: normal; COLOR: rgb(50,50,50); FONT-SIZE: 13px; FONT-WEIGHT: bold; WORD-SPACING: 0px; font-variant-ligatures: normal; font-variant-caps: normal; -webkit-text-stroke-width: 0px">ns3::ndn::NetDeviceLinkService</span> ,But
I want to caculate the hop value directly in Interest. If it works ,I
can add other member variable in Interest which is quite important
for my research.Thank you very much .</div>
