I just want to make sure that you may need to:</div><div>1) If you plan to run your custom app on >1 nodes, you may need to create and install <i>channels</i> between two faces on two different nodes. </div><div>2) Add routes to the correct face.</div><div>If face_1 is on node_1 and face_2 is on node_2. You need to do AddRoute(node_1, prefix, face_1, xx) and AddRoute(node_2, prefix, face_2, yy). This will tell node_1 to forward the given prefix to face_1. Then, <i>Channels </i>will forward them to the other end.</div><br><div>Usually when we run simulations on NDN, we do not install the route (AddRoute) inside the application. Instead, we create a consumer, a producer, a channel between them, and add routes between two nodes.</div><div>
<div>AddRoute has an overloaded function that takes two nodes as parameters. </div><div><a href="https://nam10.safelinks.protection.outlook.com/?url=https%3A%2F%2Fndnsim.net%2Fcurrent%2Fdoxygen%2Fndn-fib-helper_8cpp_source.html%23l00085&data=05%7C01%7Cpfang%40umass.edu%7Ca390ac0861af429adeb908db30d92f2d%7C7bd08b0b33954dc194bbd0b2e56a497f%7C0%7C0%7C638157481592274078%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=gPK9R96BIEig6SJR0mlau5uCVtRBtiSNF2T7NujsCH0%3D&reserved=0" rel="noreferrer noreferrer noreferrer noreferrer noreferrer noreferrer noreferrer noreferrer noreferrer noreferrer noreferrer noreferrer noreferrer noreferrer" target="_blank">https://ndnsim.net/current/doxygen/ndn-fib-helper_8cpp_source.html#l00085</a></div><div>For example, you can alternatively do AddRoute(node_1, prefix, node_2, xx) outside your application classes. This helper function will look up the other end of its installed channel to find the outgoing face.</div><div><br></div><div>In an ideal case, if you want a node to act as both consumer and producer, you may want to create two different applications and install them on the same node. I personally did not try creating an application that acts as both, but it technically <i>should</i> work.<br></div><div dir="auto"><br></div><div dir="auto">Note that in the ndnSIM examples on custom apps: <span style="font-family:"lucida grande",verdana,geneva,arial,sans-serif;font-size:14.6667px;text-align:justify;background-color:rgb(255,255,255)">(</span><code style="text-align:justify;background-color:rgb(255,255,255)">ndn-simple-with-custom-app.cpp</code><span style="font-family:"lucida grande",verdana,geneva,arial,sans-serif;font-size:14.6667px;text-align:justify;background-color:rgb(255,255,255)">).</span> Only one node is installed--so no channels--and Interest is sent to the same node.

am currently working with ndnsim and have a query regarding the
handling of Interest and Data packets. While attempting to implement
certain operations upon the arrival of these packets, I have noticed
that while the "App::OnInterest(Interest)" function works as expected,
the "App::OnData(Data)" function does not seem to be called when the
Data packet arrives. My intention is to log some information upon the
arrival of Data packets.</p><p>I can confirm that the Data packets are
indeed arriving at the node and being forwarded correctly. Could you
please advise me on what could be causing this issue?</p><p>Thank you for your time and assistance.</p><p>Best,
