Limiting bandwidth to intranet

guys,
        in my squid.conf file , i have this entry :

acl all src 192.168.0.0/255.255.255.224 199.108.222.160/255.255.255.224
    192.168.0.240/255.255.255.240 202.58.117.0/255.255.255.240
    202.58.117.192/255.255.255.240 202.58.117.240/255.255.255.240
acl manager proto cache_object
acl localhost src 127.0.0.1/255.255.255.255
acl SSL_ports port 443 563
acl Safe_ports port 80 81 21 443 563 70 210 1025-65535
acl Dangerous_ports port 7 9 19 22 23 25 53 109 110 119
acl CONNECT method CONNECT

acl fullspeed dst all
acl intranet src 192.168.0.0/255.255.255.224
delay_pools 2
delay_class 1 1
delay_class 2 1
delay_access 1 allow intranet
delay_access 1 deny all
delay_access 2 allow intranet
delay_access 2 allow fullspeed
delay_access 2 deny all
delay_parameters 1 4000/4000
delay_parameters 2 -1/-1

---------
my purpose of the delay_pools feature is to limit our intranet bandwidth
consumption to 32kbits/s for the internet and fullspeed for local
networks.
are my entries correct ? please comment out

:) TIA
