<div dir="ltr">Hi Alex,<br><br>Thank you for your answer. I've tried ncc, acces, client control, multicast, and broadcast strategy, but the result is not like my expectation.

<br>
The behavior you're seeing is because of the simple strategy (BestRoute) you're using. This strategy has no intelligence driven by the data plane performance and only uses input from the routing plane (e.g., manual route configuration).<br>
<br>
If you select NCC strategy, for example, you should be able to see different behavior:<br>
<br>
...<br>
ndn::StrategyChoiceHelper::InstallAll("/prefix/sub", "ndn:/localhost/nfd/strategy/ncc");<br>
...<br>

Everytime I run the program, packet interest that's been sent always pass through the nodes that affected by hijack(R3-H), although in the topology that I made there are other path that aren't affected by hijack(R2). Could you tell me how to make the packet interest choose another path that aren't affect by the hijacker(change to R2 when first attempt was hijacked by R3-H)? Is it possible to do that?<br>
