[Ndn-interest] Data not received from NDN traffic generator

[Junxiao Shi]

Hi Navdeep

I'm looking at the last few lines of the log file.
It appears that there's some loop going on in the network. It's
particularly strange that face 262 receives an Interest with duplicate
Nonce within 0.2ms of sending it.
InterestLifetime is set to 200ms, but the producer spends 500ms to generate
Data. A longer InterestLifetime is needed; the consumer needs to send
Interests at a slower rate; the producer needs to generate Data faster (eg.
set digest signing instead of RSA).
Also, you mentioned there are 2500 Interests, but I only see a small number
of distinct names.
