How to configure squid delay Pools with Per User, Per IP, Browser, Window based Restriction, bandwidth Management, YouTube Streaming, Upload, Bucket<\/p>\n

\n

Squid delay pools Configuration Examples
\n<\/b><\/u><\/h2>\n

User based bandwidth Restriction, browser window based limit Examples.<\/p>\n

Delay pools are used for limiting the bandwidth of web traffic. We can restrict bandwidth based on source ip address, destination ip address, source domain, and destination domain.<\/p>\n

1) URL, keyword based bandwidth restriction <\/b><\/u><\/h3>\n

This will limit the bandwidth for the following keywords video.domain.com mail cricket<\/p>\n

acl group1 url_regex -i video.domain.com mail cricke<\/b><\/div>\n
delay_pools 1
\ndelay_class 1 1<\/b>
\n# 256 Kbit\/s fill rate, 1024 Kbit\/s reserve
\ndelay_parameters 1 32000\/128000
\ndelay_access 1 allow group1<\/b><\/div>\n

2) IP Based Restriction<\/b><\/u><\/h3>\n

Below configuration will restrict bandwidth for the ip range 10.5.1.1-10.5.1.255 and allow full bandwidth for the rest of all
\n<\/b><\/p>\n

acl ipgroup src 10.5.1.1-10.5.1.255\/32<\/b><\/div>\n
delay_pools 1
\ndelay_class 1 1<\/b>
\n<\/b># 256 Kbit\/s fill rate, 1024 Kbit\/s reserve
\ndelay_parameters 1 32000\/128000
\ndelay_access 1 allow ipgroup<\/b><\/div>\n
delay_access 1 deny all<\/b><\/div>\n

3) User group based restriction<\/b><\/u><\/h3>\n

Restrict bandwidth for user1,2,3
\n<\/b><\/p>\n

acl restuser proxy_auth user1 user2 user2<\/b><\/div>\n
delay_pools 1
\ndelay_class 1 1<\/b>
\n<\/b># 256 Kbit\/s fill rate, 1024 Kbit\/s reserve
\ndelay_parameters 1 32000\/128000
\ndelay_access 1 allow<\/b> restuser <\/b>\u00a0<\/b><\/div>\n
delay_access 1 deny all<\/b><\/div>\n

4)time based bandwidth limit<\/b><\/u><\/h3>\n

For time based bandwidth limiting, use the below acl
\nacl Night_time time SMTWHFA 20:00-24:00
\nacl Morning_time time SMTWHFA 00:00-08:30<\/p>\n

Delay Class<\/b><\/u><\/h3>\n

Class of the delay pool used is defined using this tag. There must be exactly one delay_class line for each delay pool. There are five categories of delay classes.<\/p>\n

class 1\u00a0\u00a0 \u00a0 <\/b>Everything is limited by a single aggregate bucket.
\nclass 2\u00a0\u00a0 \u00a0 <\/b>Everything is limited by a single aggregate bucket as well as an “individual” bucket chosen from bits 25 through 32 of the IP address.
\nclass 3\u00a0 <\/b>Everything is limited by a single aggregate bucket as well as a “network” bucket chosen from bits 17 through 24 of the IP address and a “individual” bucket chosen from bits 17 through 32 of the IP address.
\nclass 4<\/b>\u00a0 Everything in a class 3 delay pool, with an additional limit on a per user basis. This only takes effect if the username is established in advance – by forcing authentication in your http_access rules.
\nclass 5<\/b>\u00a0 Requests are grouped according their tag<\/p>\n

5) Limiting bandwidth usage both overall and per-user <\/b><\/u><\/h3>\n
acl all src all
\ndelay_pool_count 1
\ndelay_class 1 2 # delay class2<\/b><\/div>\n

#overall speed(1MB=1000\/8*1000=125000) and the per-IP speed(25k)
\ndelay_parameters 1 125000\/125000 25000\/25000
\ndelay_access 1 allow all<\/b><\/p>\n
