[ns] hier address used in wireless

["ncs" <ncs@hbhs.buaa.edu.cn>]

hi all,
I am not clear about the domain and cluster setting.
eg:                           5 
   0----1----2----3----4      6 mn
   s    e1  core  e2   bs     7
If i set domain_num_=3, cluster_num=1 1 1, eilastlevel=1 3 4
or domain_num_=3, cluster_num=1 3 1, eilastlevel=1 1 1 1 4

what's the difference between the two cases?
Can they both function correctly, or which is the better?

If I simulate diffserv in wireless, Can this topo achieve it?

thanks in advance.
