How are you expecting to know PIT sizes, and which PIT sizes are you thinking about? On the consumer node (kind of possible, but requires communicating between app and ndn::L3Protocol)? If you want something more, you will need to implement some additional protocol to exchange PIT sizes and communicate them back to the consumer, but I'm not sure how can that be implemented. Of course, in the simulator you can cheat in many ways and get hold of any node from any other node, but it still would require some deep hacking.</div><div><br></div><div>As for changing interest lifetime, there is a call GetInterestLifetime and SetInterestLifetime in ndn::Interest class. You can use them to get/set lifetime of a specific interest. </div><div><br></div><div>---</div><div>Alex</div><br><div><div>On Apr 27, 2013, at 6:06 PM, "Xee" <1839750381@<a href="http://qq.com">qq.com</a>> wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div>Hi Alex</div><div><br></div><div>Thanks for your email, I want to change the lifetime of Interest packets both at the consumer and producer side.
