Not really. There existed distributed fastswitching before DCEF came 
along. It might still exist. CEF was developed to address the issue of 
route cache insertion and purging. The unneccessarily painful 60 second 
interval new destination stall was widely documented before CEF got 
widespread use. The "fast switching" approach was also particularly 
painful when DDOS attacks occurred.
