Subject: [ndnSIM] simulate an IP-overlay network
Message-ID: <4f6ff018.47b.14bd6086a65.Coremail.yunlzy@126.com>

 
Hi:
       I want to simulate an scenario with NDN as an ip-overlay network, which need to send package between ip and ndn nodes(that's the only way i can find to simulate an ip-overlay network). Can ndnSim do this?
       I know in ndnSIM1.0 a class named IpFacesHelper can help me with this problem, but what can i do in ndnSIM2.0?
       Or is there any better idea for me to do a simulation with ip-overlay scenario?
       Thanks very much.
Regards,
Cobb

Hi,

For preventing the buffer overflow, I would like to setup the notification
message, in which the intermediate node generates notification message (on
buffer threshold) to its downstream node.

Any idea on how Intermediate node can generate notification message to its
downstream node, will be appreciated.


Thank you in advance for your help.

Hello,

interesting question...

I think that a convenient way to do so is to define an application that will run on the intermediate nodes and will send notifications to a downstream node based on the desired conditions. At least, this would be the way that I would start implementing it.

Another way to do so (I do not think that it is quite convenient though) is to change the forwarding pipelines of NFD so that to send notifications to a downstream node based on the desired conditions.

Dear Sir,

Thanks for the feedback. i  defined the application that run on
intermediate nodes but the only problem i have , it forwards the
notification to upstream node instead of downstream node.
With Regards,

 Hello,

NDN can run on top of every protocol and ndnSIM implements this primitive.
Therefore, you have to use the implementation of the protocol that you want in your scenario and then run NDN on top of it.

Subject: [ndnSIM] Assert in TypeId::LookupByName: error. Could not find the
	class.
Message-ID: <CAHVD1ibyM+ptu+pg9dwcssnvyUp4B2X10L_DbZbT-2jOfC8esw@mail.gmail.com>

Hi,

When we are using AppHelper to install applications on a ndn Node, which
application classes are supported and how?

For example, in one example code, following few lines installs a Consumer
application on the ndn node.

 86   ndn::AppHelper consumerHelper ("ns3::ndn::ConsumerCbr");
 87   consumerHelper.SetPrefix (prefix);
 89   consumerHelper.Install (consumerNodes);


However, I do not see how the ndn-consumer-cbr.h/.cc files are getting
compiled?

I am trying to add a new type of application by defining its own class. I
think I have coded it right (e.g. TypeId method, and
calling NS_LOG_COMPONENT_DEFINE
("ndn.SampleApp"), NS_OBJECT_ENSURE_REGISTERED (SampleApp); macros.

 28 TypeId
 29 SampleApp::GetTypeId (void)
 30 {
 31   static TypeId tid = TypeId ("ns3::ndn::SampleApp")
 32     .SetGroupName ("Ndn")
 33     .SetParent<App> ()
 34     .AddConstructor<SampleApp> ()
 35   ;
 36   return tid;
 37 }


But I consistently get the below error.

assert failed. cond="uid != 0", msg="Assert in TypeId::LookupByName:
ns3::ndn::SampleApp not found", file=../src/core/model/type-id.cc, line=539
terminate called without an active exception


Do we have include this file into (which?) any of the wscript to be able to
compile it?

/anil.

Subject: [ndnSIM] Question about disabled links coloring faces red
Message-ID: <54F49198.2070001@gmail.com>

First of all hi everyone, being the first message on the mailing list I 
suppose it's the least courtesy for me to say it. ;)

Second, and probably more important, I do have a question about the 
behaviour of ndnSIM on green-yellow-red nodes.

I do have a custom application (which is basically a request n 
sequential packets so not important here I think) installed on a few 
nodes, a few others are producers and they are all randomly placed on a 
grid layout with PointToPoint connections, where all nodes have the 
basic ndn stack installer through the helper.
We are still using (due to it being a long project) ndnSIM 1.0, 
Forwarding strategy is BestRoute, we use the GlobalRoutingHelper and 
invoke its CalculateAllPossibleRoutes before running the simulation, so 
not only the optimal paths are mapped, but all, as confirmed in the 
visualizer in the node's FIB.

Now, we also implemented a Failer class which each n seconds fails all 
node links for m seconds (using the GetFace(x)->SetUp(false/true) 
methods for each face).
The problem is that when the failed node is on the path between the 
consumer and the producer all interests stops at the failed link, 
without going to an alternative (originally suboptimal) path.

Shouldn't the faces going to the interrupted path be marked red instead 
of yellow so the routing can choose the second best one?

Doesn't ndnSIM manages this in some way more or less automatically? Does 
it changes bewtween ndndSIM 1.0 and 2.0?

Am I completely off the road and have totally misunderstood how this 
works, or missed a very obvious part of the documentation? (If so I'm 
sorry for wasting your time, but please explain me how so)

Thank you very much and I'll be waiting for pointers (eh eh, C joke ^^).

Riccardo

Hello,

possible reason for that:

Is the notification expressed as an interest packet? If so, you have to think about its name prefix. If there is a FIB entry to an upstream node for this name prefix, it is normal to be forwarded upstream. In this case, probably you need either to change name prefix and add manually a FIB entry for that name prefix, or manually install a longer prefix match FIB entry for the name prefix of your interest.

Hi Lan,Thank you for your guidance.I want actually connect two clusters (such as two smart grids or two vehicle networks) through NDN. I am trying to get the fundamental understanding to how it is possible to connect two clusters via NDN. for instance, how change the traffic from clusters to the Interest/Data and in reverse.
If there is any useful material, I am very thankful to share with me.

Sincerely,
Armin

Armin,

Do you mean that the traffic in the clusters is not NDN traffic but you want to convert the traffic to NDN at the border routers?  I'm not sure how to do this.  For some applications (e.g., http like traffic), this may be possible.  But it's application specific, not something you can do regardless of the application.

Message-ID: <CANO3Hx1HWktKOh8oXoghW0Feu3WqfntwFxHEjQaYuTVcWx8RrA@mail.gmail.com>

Hello.

I ran ndn-congestion-alt-topo-plugin example with FibHelper.
but it seems the producer doesn't send a data packet.

18 p1 257 appFace:// InData 5.24288e-12 5.4272e-12 0 0
18 p1 257 appFace:// OutData 0 0 0 0

Does anyone know why?

Do I have to designate Fib routing path?

  ndn::FibHelper::AddRoute("c1", "/data", "n1", 1); // link to n1
  ndn::FibHelper::AddRoute("c2", "/data", "n1", 1); // link to n1
  ndn::FibHelper::AddRoute("c3", "/data", "n1", 1); // link to n1
  ndn::FibHelper::AddRoute("c4", "/data", "n1", 1); // link to n1

  //ndn::FibHelper::AddRoute("n1", "/data", "n2", 1);  // link to n2
  ndn::FibHelper::AddRoute("n1", "/data", "n12", 2); // link to n12

  ndn::FibHelper::AddRoute("n12", "/data", "n2", 1); // link to n2

  ndn::FibHelper::AddRoute("n2", "/data/p1", "p1", 1); // link to p1
  //ndn::FibHelper::AddRoute("n2", "/data/p2", "p2", 1); // link to p2
  //ndn::FibHelper::AddRoute("n2", "/data/p3", "p3", 1); // link to p3
  //ndn::FibHelper::AddRoute("n2", "/data/p4", "p4", 1); // link to p4

  ndn::FibHelper::AddRoute("p1", "/data/p1", "n2", 1);
  ndn::FibHelper::AddRoute("n2", "/data", "n12", 1);
  ndn::FibHelper::AddRoute("n12", "/data", "n1", 2);
  ndn::FibHelper::AddRoute("n1", "/data", "c1", 1);

Does anyone know how to forward data packet from p1?

  ndn::FibHelper::AddRoute("p1", "/data/p1/1", "n2", 1);
  ndn::FibHelper::AddRoute("n2", "/data/p1/1", "n12", 1);
  ndn::FibHelper::AddRoute("n12", "/data/p1/1", "n1", 2);
  ndn::FibHelper::AddRoute("n1", "/data/p1/1", "c1", 1);

I am not sure this way is right.

Message-ID: <CADQiFJZecGsY8dappQSE3=ViP5zVvu1=g_-mA2GFxkXt0zEkRA@mail.gmail.com>

Hello,

     My project is about Mitigating the interest flooding attack. Finally I
have to stop the attacker from sending malicious interest packet. For that
, I need to send fake data packet to the attacker. Is it possible to send
fake data packet from intermediate routers.? if so.. how.?

regards,

Ram Dinesh

I'm not aware of any existing guidelines.  But I guess you can run a proxy on one router that converts the HTTP requests to NDN Interests and another proxy on the other router that converts HTTP responses to NDN Data packets.  I don't understand why you want to do this kind of translations though.  It may be much easier to just rewrite the existing applications to NDN applications.

Hi,
Yes, I want to connect two different traffics through the NDN.
You said for some applications such as http, it is possible. Is there guideline?

Armin,

Do you mean that the traffic in the clusters is not NDN traffic but you want to convert the traffic to NDN at the border routers?  I'm not sure how to do this.  For some applications (e.g., http like traffic), this may be possible.  But it's application specific, not something you can do regardless of the application.

Hi Lan,
Thank you for your guidance.
I want actually connect two clusters (such as two smart grids or two vehicle networks) through NDN. I am trying to get the fundamental understanding to how it is possible to connect two clusters via NDN. for instance, how change the traffic from clusters to the Interest/Data and in reverse.

If there is any useful material, I am very thankful to share with me.

Hey Guys,

I just gone through NLSR paper, where they have mentioned that they are
sending status (echo) messages to neighbor to check whether its alive or
not (basically for tracking) which is a kind pf ping utility.

I wonder is there any other mechanism in NDN protocol stack that we can
check or verify weather connected link or neighbor node is reachable or
alive or not?

Thank you guys.

Are you talking about the Hello messages (we call it INFO message in the paper)?  This is something NLSR sends, since it's used to detect whether NLSR is alive or not.  So you can't use something else to replace it.   For example, if there's link layer mechanism to detect link failures, that will help trigger routing calculations faster in this case.  But the link layer failure detection is not going to detect NLSR failure.

That said, NLSR does receive notifications from the local NFD when a face goes down or up.

Hello,

you probably need to code an application and install it on the intermediate routers. This application can send the data packets that you want. However, if your data packets are unsolicited, NFD will drop them for security reasons. In this way, if a ?fake? packet satisfies a PIT entry, the original packet, which will be received later, would be considered as unsolicited and get dropped. If you want to forward both the ?fake? and the original packet, you will have to take care of maintaining the PIT entry after the arrival of the ?fake? packet.

HI Prof. Wang,

Yes, it is "Hello" messages. It was typo ( NLSR sends "info" interest), I
apologies for it. I completely agree on it.  Now I got to know NLSR failure
and detections. Yes, It will help to trigger routing calculation faster,

Thank you for clarifying :)

Regards,
Hitesh

You cannot just forward data packet in NDN. There has to be interest received by p1 producer for the data packet to travel back to the consumer.  FibHelper::AddRoute provide configuration for the interest paths.

I ran ndn-congestion-alt-topo-plugin example
but the consumer couldn't get data packet from p1
that is why I am asking you.

I am still digging to find the reason why consumer couldn't receive data
packet from p1.
If someone knows about this. please let me know.
ndn::FibHelper::AddRoute is only related to interest packet not data packet?

Subject: [ndnSIM] Implementing My Own Cache Policy
Message-ID: <54F96ED9.3040603@inl.ics.keio.ac.jp>

Hello all,

After I have read through documentations of ndnSIM 1.0, especially the 
source codes of the provided basic cache policies, I have some questions 
about them as well as questions about trying to create my own cache 
policy  as follows.

1. Referring to the source code of LRU policy (lru-policy.h), what are 
the roles (functions) of codes from line 39 to line 47? I have crossed 
check with the code of empty policy (empty-policy.h) and I found that 
such codes are not necessary for the case of policy that does not 
implement any algorithm.

2. From line 89 to 96 of the same file (lru-policy.h), the "lookup" 
function is implemented there. Why doesn't it handle the case of cache 
miss? Based on the code, it seems to me that this case is not handled at 
all.

3. It seems to me that the "policy_container" in the code serves as a 
cache storage (list). In that case, how can I check for the list of 
available functions I can call? I wonder if there are functions I can 
use to access specific orders of cached objects in the list. Is there a 
way to set IDE to automatically display a list of possible related 
functions?

4. This question is about the policy I would like to implement. How can 
I make nodes automatically send messages about some of the contents of 
their stored cache objects to next neighbor nodes? Is it better to 
implement this detail in the same cache policy file or different files 
at different levels? Please kindly provide some suggestions.

Thank you for your responses in advance.

I am looking for control commands. How can I generate control commands from
application? what are the steps for it? any references or links would be
helpful.

For instance, I want to add or updated 'routes' or nexthops in FIB using
control command ("/localhost/nfd/fib") from application. I tried to search
in mailing list first, but I wasn't able to find any comments or references
on it.

Also, I think currently, in NFD, its not possible that remote application
can configure destination NFD using control command?  Please correct me if
I am wrong.

I want to send a control message from a node to its neighbor. So, I use an Interest with a new Nack value.
My question is how can I identify a message  sent by the node's application layer or a message received from its neighbor (in OnInterest  method in forwardingstarategy class).

I try to use the following code, but it doesn't work.
TypeId faceType = inFace->GetInstanceTypeId();
 std::string faceType_name = faceType.GetName();
if(faceType_name.compare("ns3::ndn::AppFace") == 0 )
    {
	// from my application
    }
    else
    {
    // from my neighbor
    } 

Can you give me a hint?

I need to do with multiple prefixes, but how can I grab the seq no of 
prefix
so that I can work with prefixes as a list ?
Thanks.

Hi,
I'm using ndnSim 1.0.
Is there a way to disable caching for some data packets?
For example, data packets named with /prefix_10 will not be cached while
all other data packets will be cached normally.

Hi Hisham,

There is no built-in way to do that, but you can always hack in the replacement policy and add something like

in insert method (see model/cs/custom-policies/* as a reference):

      inline bool
      insert (typename parent_trie::iterator item)
      {
        static const Name& prefix("/prefix_10?);
        const Name& name = item->payload ()->GetData ()->GetName ();
        if (prefix.IsPrefixOf(name))
          {
            return false;
          }

         ... whatever existing code in insert method
      }

?

Hi Trade,

I?m not sure I fully understand your question.

Assuming sequence number is at the last component of data name, you can do something like (in ndnSIM 2.0, 1.0 will have slightly different syntax)

data.getName().get(-1).toSeqNo();

Did you mean something else?

?

Hi,

Before running InstallAll method, you would also need to call

  StrategyChoiceHelper::Install<nfd::fw::BestRouteStrategy3>(someNode, prefix);

(this will make sure strategy is available on node ?someNode?).

Hello,

there are some calls of a method ?dispatchToStrategy" in forwarder.cpp. This method will find and call the right forwarding strategy. You can pass your variables as arguments to this method.

Hi,

 

not sure if it is on purpose, but if I do

git clone https://github.com/cawka/ns-3-dev-ndnSIM.git ns-3
<https://github.com/cawka/ns-3-dev-ndnSIM.git%20ns-3> 

I still get the version without the changes for the ndnSIM 2.0 scenario
template.

I had to manually switch to the ndnSIM-v2 branch, else I would get the error
message that the header file "common.hpp" could not be found.

 

Best regards,

Christian

Hi!

Given nanoseconds-to-seconds conversion includes information truncation, you would need to explicitly specify this intention using duration_cast method (you can check more about duration_cast in Boost.Chrono documentation http://www.boost.org/doc/libs/1_57_0/doc/html/chrono/users_guide.html <http://www.boost.org/doc/libs/1_57_0/doc/html/chrono/users_guide.html> or in std::chrono docs http://en.cppreference.com/w/cpp/chrono/duration/duration_cast <http://en.cppreference.com/w/cpp/chrono/duration/duration_cast>):

There is also a small problem with your example. time::steady_clock::now() returns a so called ?time point? (time duration since some fixed epoch).  More correct example would look similar to:

  ::ndn::time::steady_clock::TimePoint now = ::ndn::time::steady_clock::now();
  ::ndn::time::seconds sec = ::ndn::time::duration_cast<::ndn::time::seconds>(now.time_since_epoch());

Message-ID: <CAHVD1ibQNX-5i5cxKadJLjyuRJC=neOgoA_SOQy1HygJmcn49g@mail.gmail.com>

https://github.com/named-data/ndnSIM/blob/master/examples/ndn-custom-apps/custom-app.cpp


In this custom-app.cc code (line: 88), I think it is sending the Interest
on face created by the application (ndn-app). However, how the scenario is
handled where there are more than one faces on given node? How a particular
face is selected to send the Interest on? In my simulation setup, I have
multiple faces on given node.

When Interest/Data is received, a respective handler is called (line: 93 or
116). I believe this handler is called for all Interests/Data messages
received from all interface, correct? It is the application, based on the
Interest name, carries out different processing as per the application
context. Am I correct?

I saw in one of the application code, an ExpressInterest() API, where one
can specify the exact call back to handle Data. However in the above code,
this looks like abstracted out. Is it still possible to use the
ExpressInterest API? To put it other words, I did not understand how
Interest is actually being sent out to the face. How does this works in the
above sample code?

Hello Anil,

I will try to answer your questions:

First of all, the application face is different than the NetDevice Face, which is used for the connection among the simulated nodes. Both of them are realizations of the NFD Face class. The NFD Face class is the base class, which is used during the Interest/Data processing from NFD. For further details, you can take a look at our Technical Report:

http://named-data.net/publications/techreports/ndn-0028-1-ndnsim-v2/

> In this custom-app.cc code (line: 88), I think it is sending the Interest on face created by the application (ndn-app). However, how the scenario is handled where there are more than one faces on given node? How a particular face is selected to send the Interest on? In my simulation setup, I have multiple faces on given node.

Each application, that you will define in a simulation scenario using the AppHelper, will have a face associated with it. In this way, an Interest packet will be sent out of this application face to NFD for further processing and then to other nodes using the netDeviceFace. I do not think that there are any reasons to have multiple faces for the same application instance on a single node. However, you can install multiple application instances on the same node.

> When Interest/Data is received, a respective handler is called (line: 93 or 116). I believe this handler is called for all Interests/Data messages received from all interface, correct? It is the application, based on the Interest name, carries out different processing as per the application context. Am I correct?

What do you mean by ?all interfaces?? Application faces, NFD faces, NetDeviceFaces?

> I saw in one of the application code, an ExpressInterest() API, where one can specify the exact call back to handle Data. However in the above code, this looks like abstracted out. Is it still possible to use the ExpressInterest API? To put it other words, I did not understand how Interest is actually being sent out to the face. How does this works in the above sample code?

An Interest starting from the application face will be send to NFD for further processing. If there is a FIB entry for the expressed name prefix, the interest will be sent to another node.

Hope that this helps.

Hi Spyridon.

Thank you for your comments. They are elaborate! I have added few further
notes.

I am writing a simulation for a protocol where multiple nodes are involved.
In my topology, a given node may be connected to multiple other nodes. I
have written an application (derives from "ns3::ndn::App" class), which is
installed on node. Right now, I am more thinking from this application
perspective, hence my earlier email.

I will read the technical report.

[anil] Ok. "more than one faces on given node" - I was talking about when a
node is connected to more than one remote nodes. So if I understood you
correctly, there will be multiple netDeviceFace(s) depending on how node is
connected to other nodes.
I agree that there is no need to have more than one application faces
between application and NFD. However, if I have to send an Interest to
specific node, can't I use a specific netDeviceFace instead of depending on
NFD and FIB entries? Is that possible?

[anil] I meant the Interest/Data messages received from remote devices. So
it is netDeviceFace. But now, I see that these handlers (OnInterest, and
OnData) are application level handlers (point of entry), and the lower
layer (e.g. NFD) is going to post Interest/Data messages to the application
over application face. Application then handle/process these Interest/Data
depending on the "name"space, correct?

[anill] I was more concerned about the Ingress Interest/Data message. So to
extend my above comment, when application receives Interest/Data message,
the OnInterest/OnData is called by the simulator framework respectively,
and/or we can specify the function to be called back - on receiving
Interest/Data - by using ExpressInterest() API. Is this correct?

Subject: [ndnSIM] Implementing My Own Cache Management Policy
Message-ID: <5512ECD5.5020004@inl.ics.keio.ac.jp>

Hello all,

I am currently using ndnSIM 1.0, and I have been trying to implement my own cache management policy for a while already. However, I have quite a lot of questions to ask as follows.

1. Referring to the source code of LRU policy (lru-policy.h), what are  the roles (functions) of codes from line 39 to line 47? I have crossed  check with the code of empty policy (empty-policy.h) and I found that  such codes are not necessary for the case of policy that does not  implement any algorithm.

2. From line 89 to 96 of the same file (lru-policy.h), the "lookup"  function is implemented there. Why doesn't it handle the case of cache  miss? Based on the code, it seems to me that this case is not handled at  all.

3. It seems to me that the "policy_container" in the code serves as a  cache storage (list). I wonder if there are functions I can  use to access specific orders of cached objects in the list at a particular time. Let's say I would like to get the first 5 contents which are stored in the cache storage. How can I possibly do that?

4. This question is about the policy I would like to implement. How can  I make nodes automatically send messages about some of the contents of  their stored cache objects to next neighbor nodes? Is it better to  implement this detail in the same cache policy file that I am going to create, or in different files  at different levels? Please kindly provide some suggestions.

5. When I simulated the example file "ndn-simple-with-cs-lfu.cc" using the visualizer, I discovered that the request from consumer node still reaches the producer node even after the intermediate router has received the requested content from producer at least once. (The second request from consumer node is sent before the content in the cache of the router expires.) If cache is enabled at the router, why does the later requests (after the first one) still reaches the producer node? Why doesn't the router serve the request with its cache content?

Thank you for your responses in advance.

Kanin Assantachai

Subject: [ndnSIM] Introduce delay
Message-ID: <9a52d4557794c7027525a1386def4312@scss.tcd.ie>

Hello everyone,

I am looking on how I can calculate the cost that a PIT lookup would 
introduce.

I have found a solution where a Schedule Event may be used for it but I 
want this to be called in e.g. my OnInterest or OnData function. 
However, I haven't found a way that I can force the function to "wait" 
until the execution of this event occurs.

In this relevant post
http://www.lists.cs.ucla.edu/pipermail/ndnsim/2013-May/000542.html
I found that additional modules are necessary so as to implement 
something like this. Could someone please advice me on how to proceed?

Thanks in advance,
A.

Hello,

the most convenient way that I can think of right now is to define get/set methods in the forwarder script in order to get/set a ns3::Ptr to the node as a private variable. You will also need to modify a little bit the L3 Protocol class. I have done something like this here:

https://github.com/spirosmastorakis/ndnSIM-development/blob/master/model/ndn-l3-protocol.cc#L97
https://github.com/spirosmastorakis/ndnSIM-development/blob/master/NFD/daemon/fw/forwarder.cpp#L59

Hello Alex and Spyridon,

It's been more than a day since I sent an email about this set of 
questions already, but I have not received any response yet. I 
understand that I have asked quite a lot of questions, so it may take a 
while to completely answer all of them. May I ask if you are working on 
replying to my questions? Have I done anything wrong in my previous 
email? I truly need help from you.

Hello everyone,

I am currently using ndnSIM 1.0, and I have been trying to evaluate by a
metric like path stretch factor, but while including the hearer
"weights-path-stretch-tag.h", I get the {fatal error:
weights-path-stretch-tag.h: No such file or directory}!
When I searched, I understood that this header file is in a folder named:
tracers-broken! Is there any problem with these or my problem is somewhere
else? Is there any sample?

Thanks in advance
