CISCO ROUTER

I have a Cisco 3600 series router and using this as gateway for nearly 200 machines for the internet. Suppose if want to download or upload into a ftp site it takes more time for that since the bandwidth is being shared by more than 200 machines ata given point of time. Is there any option in the Cisco so that we can set the bandwith for a particular machine so that it gets that dedicated amount of bandwidth.
