Hello, In the NS routing scheme, there MUST be a classifier in the node whose slot entry (assuming the dest in NOT the same node) points to the link (link head_), on which the packet will be sent out. Isn't it ? If so, is it the address classifier ? I am trying to determine the node and the next hop node in the classifier and am having hard time at that. Can someone give me a clue? thanks, Prasad.
