There is another question regarding in which latency you're interested: just Interest-Data or first Interest for sequence number and reception of Data (which includes all the retransmission delays). Currently in ndn::Consumer-based apps, there is tracking of just Interest-Data packets (i.e., without retransmission delays) within RTT estimator variable (Ptr m_rtt) and in timeout container (SeqTimeoutsContainer m_seqTimeouts). If you want/need the other delay, including all retransmission timeouts, then it should be straightforward to implement, for example, using SeqTimeoutsContainer structure (similarly how m_seqLifetimes in ndn::Consumer). I think, and would do it when I can get time for that, it is a good idea to export both delay parameters as a trace sources in ndn::Consumer class, as well as write a simple metric helper. --- Alex On Jan 16, 2013, at 5:36 AM, Xiaoke Jiang wrote: > Hi All, > How to trace the latency of request, duration from sending the Interest to receiving corresponding Data. > > Is there anyone can give some hint?

Now it should be more consistent. In case that would be helpful, I also have added number of Interest retransmissions for FullDelay parameter. In addition to that, I've did a little bit of implementation regarding your request for Interest/Data forwarding hop counting. I've added this parameter to the same trace helper. There are a couple tricks for new HopCount field: - HopCount is increased anytime somebody calls Send method on a face, including delivery of Interest/Data to application via an AppFace (but not from application to ndn::L3Protocol!). - Interests satisfied by an app will have even hop count (min hop count = 2) - Interests satisfied from caches will have off hop count (min hop count = 1) --- Alex On Jan 19, 2013, at 5:21 AM, Xiaoke Jiang wrote: > Hi Alex, > I tried many case today and I think there is a logic problem during retransmission. > > for example: > 1. nodeN send seqQ, > 2. seqQ timeout and then m_seqTimeouts(seqQ) is erased and seqQ is add to m_retxSeqs container > 3. m_retxSeqs is waiting ? > 4. during the waiting, Data for seqQ comes, and it removes m_retxSeqs(seqQ), which cancel retransimssion > > In the above scenario, for latency trace will only have FullDelay but without LastDelay and some other logic problem (if you check more logs). > > solution is to modify code in ndn-consumer.cc:OnContentObject, add a "return statement" if no entry in m_seqTimeouts when content object comes > > > SeqTimeoutsContainer::iterator entry = m_seqTimeouts.find (seq); > if (entry != m_seqTimeouts.end ()) > { > m_lastRetransmittedInterestDataDelay (this, seq, Simulator::Now () - entry->time); > } else{ > NS_LOG_DEBUG("error:seq "<GetId()); > return; > } > > > thanks > > My Regards, > Xiaoke Jiang ????? > > Ph.D Candidate, > Dept. of Computer Science and Technology, > Tsinghua University, P.
