First step of network optimization

[Joe Shen <joe_hznm () yahoo com sg>]

Hi,

this may be a OOO..LD topic which is talked, discussed
or agrued for year. ISP networks may need to be
optimized continuously. But, it seems people have
different view of optimization when they use this word
 at different place; sometimes optimization means
adding more access router, add more link bandwidth or
add more servers; while it could be used  to point the
requirement on removing subareas in OSPF or simplify
network structure. 


Is there a common sense on the target of network
optimization? or is there common startup line of such
work? What should be the model of a optimized ISP
network ( or PoP site) ? 

Is there books on this topic?

Joe
