TEST PROCEDURE

  This test check following.
  
  *1: A router periodically [Query Interval] (125s) transmit

   interest on that link.
   -- in RFC2710 page 5 --

  -Test flow 
  
  1. Check Periodic General Query
     1.1. Wait General Query message from NUT on Link0,Link1
     1.2. Wait General Query message from NUT on Link0,Link1
     1.3. Wait General Query message from NUT on Link0,Link1
     1.3. Check interval of message(1.1) to message(1.2). (interval = 125s(+-2s) or not)
     1.4. Check interval of message(1.2) to message(1.3). (interval = 125s(+-2s) or not)
