Classifier and Routing?

[K Sun <ksun@essex.ac.uk>]

Hello,
     I am still confused with the relation between Classifier and 
Routing operation of ns, especially the operation of setting "slot" 
arrry.
     Actually, I have carefully read the chapter about Unicast Routing, 
but I do not find where a function of routing fills the suitable 
handlers of links (or connectors) in the "slot[]" array. 
     I have not known the function classify well. 
As my understanding, the number of elements of slot[] array ( at 
least in Address Classifier according to Figure 5.1 on page 35) should 
be one more than the number of links which are attached to this node. I 
am not sure whether my understanding is right.
     However, according to the code on page 40 and page 38, it seems 
the number of elements of "slot" arrary has should be the same as the 
number of nodes in topo because the classify function only shifts and 
masks the whole address (including node id and agent id). 

     Hope somebody may give me more implication on understanding 
classifier and routing!

     Thanks in advance,
