Hi Sabet

It?s unintentional. NFD 0.4 introduced major changes in face system, which requires significant work on ndnSIM side to keep up. You may watch https://redmine.named-data.net/issues/3560 for progress on this upgrade.
I heard Spyros, Xuxiang Tian <xuxiangtian at ucla.edu>, and Klaus all attempted to do this upgrade, but none of them has completed. If you want to work on the upgrade, I recommend you to talk to these three developers.

Yours, Junxiao

Spyridon, Alex,

Junxiao is right. Handling Link objects in forwarding has been set in Forwarder::lookupFib in NFD. The case is that ndnSIM's NFD is different with the actual one and doesn't have such handlings. The question is: What is the reason? Is it intentional? Keeping in mind that?- as far as I've found - there is no RegionTable in ndnSIM, how do you suggest me to import Link handling in ndnSIM forwarding logic.

Regards,
Sabet

Hi Fatemeh,

I suspect that you have defined PccApp in a separate .hpp/.cpp file.  Don't forget to include .cpp file to be compiled together with your simulation scenario.  If you're using scenario template, this should happen automatically though.

dont know whether anyone replied to this already: I dont think OSPFN was coded into ndnSIM, nor do we have such a plan.
One should understand that OSPFN was simply a quick hack to get NDN testbed started, not so much of a research result.

Subject: [ndnSIM] Where to Initialize network-region-table ?
Message-ID: <CADQ0MFa38VZuPvNVuch4LLDKv8stZoOSZMwVOkMrT-wY65NVoA@mail.gmail.com>

?Hi there,

I've been trying to import Feature #3034
<https://redmine.named-data.net/issues/3034/> and #3159
<https://redmine.named-data.net/issues/3159/> to ndnSIM 2.1. I've done with
network-region-table definition(NFD/daemon/table/) and modifying
onContentStoreMiss(NFD/daemon/fw/forwarder.cpp)*, which was successful. But
trying to set config section (NFD/mgmt/tables-config-section) I have
failed. I have modified *InitializeManagement()* and *reloadConfigFile()*
in ndnSIM/model/ndn-l3-protocol.cpp to set
m_forwarder->getNetworkRegionTable();

but at the end compiler gives me:

Compiling src/ndnSIM/NFD/daemon/mgmt/tables-config-section.cpp
../src/ndnSIM/NFD/daemon/mgmt/tables-config-section.cpp: In constructor
?nfd::TablesConfigSection::TablesConfigSection(nfd::cs::Cs&, nfd::Pit&,
nfd::Fib&, nfd::StrategyChoice&, nfd::Measurements&,
nfd::NetworkRegionTable&)?:
../src/ndnSIM/NFD/daemon/mgmt/tables-config-section.cpp:38:1: error:
uninitialized reference member
?nfd::TablesConfigSection::m_networkRegionTable? [-fpermissive]
 TablesConfigSection::TablesConfigSection(Cs& cs,

 ^


Could anyone please guide me where to initialize the table?

*Since the documentation has not been updated for latest version of NFD, I
preferred to go with the way NFD 0.4.0 was working. And yes! Moving Link
handling parts to strategy seems to be a good pick, because there are some
unnecessary calls for *onContentStoreMiss*(at least 3 per one ndn stack).

Thanks,
Sabet

Message-ID: <CA+fa2mUkxPv9Pz7qB83n9+cw-zg+-VrLHkXp9hOrDz4XKXEQtw@mail.gmail.com>

Hi all,

I'm updating ndnSIM.

In boost-graph-ndn-global-routing-helper.hpp of NFD 0.3.4, there is

inline property_traits<EdgeWeights>::reference
get(const boost::EdgeWeights&, ns3::ndn::GlobalRouter::Incidency& edge)
{
  if (std::get<1>(edge) == 0)
    return property_traits<EdgeWeights>::reference(nullptr, 0, 0.0);
  else {
    return property_traits<EdgeWeights>::reference(std::get<1>(edge),
                                                   static_cast<uint16_t>(

 std::get<1>(edge)->getMetric()),
                                                   0.0);
  }
}

where getMetric() returns m_metric, which seems is either 1 or 0 and is no
longer exists in NFD 0.4.2.
Could you please tell me what m_metric works for

Hi Xuxiang

GlobalRoutingHelper is not part of NFD 0.3.4, either.
It's an addition of ndnSIM and it's similar to ns3 IP global routing helper,

Hi Junxiao,

Thank you for your kind reply.
I see it, sorry for making you misunderstand, What I was trying to say is
that m_metric is part of custom version of NFD 0.3.4 or ndn-cxx 0.3.4 for
ndnSIM, but no longer exists in the current NFD or ndn-cxx. I'm wondering
what m_metric is for so that I can determine if I should re-add them in the
current version of NFD or replace with other methods.
I have solved the problem by re-adding them, suggested by Alex.
Thank you again.

Hi Xuxiang

It's great you figured out the semantics of m_metrics.
To preserve this knowledge, you can add a Doxygen comment on this variable,
so that others can understand it easier.

Yours, Junxiao

Subject: [ndnSIM] ndnSIM: Modifying Interest Packet
Message-ID: <CAJzTGNUbrnMC0Dib23m=76aALAdr5-JfpXUy_FZcWMCbDPLyFw@mail.gmail.com>

Hi Alex,

I am trying to modify Interest packet for my custom forwarding strategy in
ndnSIM 1.0. I observed that once the Interest packet (header + payload) is
serialized to the network, it cannot be modified by intermediate nodes
(e.g., in the forwarding strategy). The packet is only deserialized by
relay (or intermediate) nodes and cannot be written (or modified) by them.
I checked the source file ndnSIM/model/wire/ndnsim.cc, Serialize() and
Deserialize() functions for the same.

Is my understanding correct? Or, is there some way to write to buffer while
the packet is in network?

For e.g., FwHopCountTag is the by given as example how to add information
in payload. If one want to increment the hop count and re-write to payload
as follows:-

FwHopCountTag hopCount;
bool tagExists = packet->RemovePacketTag (hopCount);

if (tagExists)
{
    hopCount.Increment ();
packet->AddPacketTag (hopCount);
        }

This tries to increment the hopCount, but it doesn't actually increment if
I print the value. This means even though I re-write to the payload, it
doesn't update the packet.

Please let me know.

Hi Pratyush,

You're correct.  I would only restate is a little bit more general and say that NS3's Packet data structure cannot be modified by the routers.  What you can do is to make a copy of the packet and modify the copy.

I think the same applies to the tags with some exceptions that I cannot remember right now.

I observed that once the Interest packet (header + payload) is serialized to the network, it cannot be modified by intermediate nodes (e.g., in the forwarding strategy). The packet is only deserialized by relay (or intermediate) nodes and cannot be written (or modified) by them. I checked the source file ndnSIM/model/wire/ndnsim.cc, Serialize() and Deserialize() functions for the same.

Subject: [ndnSIM] Error while calling applications public member functions
 from scenario
Message-ID: <CADQ0MFYG7aMXPwEWeOCd79peDDiw4Umx5scQVjhBKmVL00N1DQ@mail.gmail.com>

Hi,

I have a custom application *"CustomApp". *I have put SendInterest() in
public so I can call it from scenario, for testing purposes. With this snap:

  ndn::AppHelper app1("CustomApp");

I'm getting:

Command ['.../ns-3/build/scratch/simple-custom-app'] terminated with signal

which buy following gdb(insight) I end up :

 It is from:
https://github.com/named-data-ndnSIM/ndn-cxx/blob/master/src/util/signal-signal.hpp:224
Branch: ndn-cxx.0.3.4-ndnSIM

I have tested app1ptr with some sample doing-nothing-but-LOG member
function and it worked.

I appreciate it if you could help me on what is wrong.

Thanks,
Sabet

Hi,

pitEntry.getInterest.getLink() compiler says:


> class std::shared_ptr<nfd::pit::Entry> has no member named 'getName'

Similar to what compiler says about getInterest. Well

What is it I've missed?

Hi Sabet

This usually occurs when you are trying to send a packet when processing a
packet. You need a io.post in real application or
ns3::Simulator::ScheduleNow in simulated application *somewhere*.

Yours, Junxiao

As Junxiao already pointed out, you cannot do this.  One of the reasons is that this code in main() function merely sets up the simulation.  The installed applications is "logically" installed on the node, and it doesn't necessarily has to start at the beginning of the simulation (it is just an accident that in your simulation it does, as you used the default start/stop times).

I would recommend checking the example applications, e.g., http://ndnsim.net/2.1/applications.html#customer-example <http://ndnsim.net/2.1/applications.html#customer-example>. You need two things,
- initiate application tasks only after StartApplication is called
- schedule send interest operation, not invoke it directly

std::shared_ptr<nfd::pit::Entry> doesn't have getName, as by .getName() you're trying to get a method of the shared pointer.  Try using ->getInterest and ->getName() instead.

Hi Xuxiang,

For common and logger, go on with:

#include "core/logger.hpp"
#include "common.hpp"

It should do it.

I guess you are missing NS_LOG_COMPONENT_DEFINE.
See

Alex,

How about setDelegation for LINKS? In ndnSIM 2.1 Interest packet is
modified(using setSelectedDelegation) under circumstances and a LOGIC log
is generated. How is that happening? buffe::reset()(which I couldn't find
it in doxygen) copies an interest and replace it with the first one?

Thanks,
Sabet

Subject: [ndnSIM] List of faces as a packet field
Message-ID: <f6d965de5f7d9023cb4de01bac996cd0@scss.tcd.ie>

Hello everyone,

I am looking to have an extra field in my packet - both Interest & 
ContentObject - that would allow me to keep a list of faces for further 
use.

This field may need to be updated at the Consumer and the Forwarding 
strategy - exclude the security logic here, please.

So, I have updated my Interest & ContentObject classes accordingly as 
well as the ndnsim.cc file. I have also included some related stuff in 
the Consumer and Forwarding strategy to be able to update the list along 
the way. I am trying to have this field as another Name type. However, I 
do get an error message when I run the simulation: i.e.
terminate called after throwing an instance of 
'boost::exception_detail::clone_impl<ns3::ndn::error::Name>'
   what():  std::exception

Eventhough, I have tried to include everything that involves the 
creation of naming into a try{..}catch{..} case, I still get that 
message which does not help me finding what am I doing wrong. I have 
also used gdb to debug and I get no related messages.

Any ideas/help/direction on what I am be doing wrong or how to proceed 
with this?

p.s. I am using the v.1 of the ndnSIM code.

Thanks anyways,
Andriana.

Hi,

I figured out that the optimized mode (./waf configure -d optimized) is causing this issue.

Message-ID: <128841FE-36EE-4D40-9193-5E5BCDDFC1A4@gmail.com>

To all,

I involve this field (ndn/ndnSIM) first time, so I confuse on some problems. As following:
1. How can I add fields in the interest packet? (May you teach me the steps?)
2. And if I add the fields, what things should I pay attention?
