INITIALIZATION

• Network Topology

          NUT(Client)
          |           
          |                        
Link0   --+--------+------------------------ 3ffe:501:ffff:100::/64
                   |
                   |          
                   TN(Server) 
   

• Verification Points



 
   RT for each subsequent message transmission is based on the previous 
   value of RT:
     

     RT = 2*RTprev + RAND*RTprev
     

   MRT specifies an upper bound on the value of RT (disregarding the
   randomization added by the use of RAND).  
    

     if (RT > MRT)
       RT = MRT + RAND*MRT

TEST PROCEDURE

        NUT      TN
        |       | 
        |       |Initialize NUT(as a DHCPv6 client)
        |       |
        | ----> |Solicit (1*)
        |       |
        | ----> |Solicit (2*)
        .       .
        .       .until RTprev = MRT + MRT*RAND 
        |       |
        | ----> |Solicit (3*)
        |       |
        |       |	

  

JUDGEMENT

  (3*)PASS: The RT must reach MRT.
