[squid-users] Volume quota management availablity

[Anoop Sreedharan]

Dear Team,
We have an IT environment catering to educational institute wherein we have
approx more than 1000 users accessing the internet.

having a volume based internet subscription, we are in need to have a
solution wherein i need to restrict users to a certain volume of quota per
month and upon crossing that threshold, need to either stop their access or
throttle their bandwidth speed.

following is the scenario. having an internet link of 50Mbps in my campus

1. users have to be authenticated via Active Directory  -- i.e. users in a
certain AD group should only get access to internet
2. should be able to define a volume threshold ( e.g 100GB per group/per
user)
3. upon exhaustion of the volume the user bandwidth should b throttled to,
say, 256Kbps. OR block internet access to that user completely.
4. this volume calculation should be done for both HTTP and HTTPS based
session.
5. should be able to generate a monthly report showcasing the volume
consumed by specific user during a specific time-frame by showing the
spread of the volume distributed within websites visited/downloaded from.

Kindly help to suggest this could be possible with Squid.
I am open to using some log analytics mechanism like sarg or anything
similar for reporting.
