Hi Jin,

Highest rank currently is defined as a face in FIB with smallest routing metric.  You can control this parameter either when you directly insert entries into FIB (http://ndnsim.net/doxygen/classns3_1_1ndn_1_1_fib.html#a62d58066a4e5f497513b795031100c91), or if you're using ndn::GlobalRoutingController, this metric will be a sum of face metrics configured in the topology.

Actually, I want to know how could you find the "Highest-Rank" GREEN or YELLOW? I can't find the define of "Highest-Rank". Maybe it just means the face which gets into the FIB earliest? Or something else?
