[ndnSIM] An error when modifying the "forwarder.cpp"

[Spyridon Mastorakis]

Hi,

I do not believe this specific error comes due to this modification. Unless, there is something that I am actually missing.

Thanks,

Hi,

I tried to reduce the frequency of forwarding interest packets by half. I only modified the code in forwarder.cpp in NS3, and an error occurred later.
Does anyone know how to solve this problem

The modified code is as follows（in forwarder.cpp）：

void Forwarder::onOutgoingInterest(const shared_ptr<pit::Entry>& pitEntry,
                Face& outFace, const Interest& interest) {
        NFD_LOG_DEBUG(
                        "onOutgoingInterest face=" << outFace.getId() << " interest=" << pitEntry->getName());


        pitEntry->insertOrUpdateOutRecord(outFace, interest);


//begin
        std::default_random_engine e;
        std::bernoulli_distribution u;
        if (interest.getName().toUri().find(std::string("manifest")) == std::string::npos && u(e)) return;
//end modify by tian 2020/10/24
        outFace.sendInterest(interest);
        ++m_counters.nOutInterests;
}

The error message is as follows：

terminate called after throwing an instance of 'boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<nfd::rib::RibManager::Error> >'
  what():  Error in setting interest filter (/localhost/nfd): request timed out




Thank you very much for your help.

Sincerely,
Gordon
