<div dir="ltr">Hi All,<div> I'm trying to create a new ndn application that sends interest packet for a content as follow:</div><div>- Each content consists of more than one segment.</div><div>- When a node wants to retrieve a content, it sends interest packets for each segment of that content (ex: if content /prefix/file01 has 2 segments the app should send 2 interest packets</div><div>/prefix/file01/01 and /prefix/file01/02)</div><div><br></div><div>My trials to do so are:</div><div>1.
