Re: Streaming Video and Internet Capacity

["Scholz, Greg" <gscholz () KEENE EDU>]

Similar here except we use Packetshaper's dynamic partitioning.

We have 90Mb and 2800 on campus students.

It seemed to help us out a lot. We let each student burst up to 3Mb.
They often don't get that much since the 90Mb cap. But we don't hear
much for complaints.

I think the worst problem we had was the students that did not
understand that all the P2P traffic their computer was serving to the
Internet affected their capacity more so then their own web surfing.

We blocked P2P last year...completely. We don't hear much for bandwidth
complaints anymore.

 

 

BTW - unless Allot figured out something that Packeteer did not, much of
the encrypted P2P (ArezWares being a big one) falls into the
unclassified traffic and therefore is not regulated by the P2P controls.

 

 

In any case, I highly advocate for dynamic partitions per user whether
you can block P2P or not.

Anne,

 

  We have heard constantly from our users "my bandwidth is better at
home - I get XMbps or YMbps or ZMbps from my cable/DSL/Whatever
provider."

 

  We are using an Allot NetEnforcer.  We have created partitions for
every student IP address.  The partition definition gives each them a
max of 5Mbps.  They can do what they will with the 5M - well we do put
restraints on P2P (750Kbps down, 56Kbps up).  

 

  This implementation has worked well for us.  Obviously we don't have
10G of bandwidth (2000 students x 5M), but the student newspaper
reported that every student gets 5M of bandwidth and we haven't heard a
complaint since (knock on wood).  This has been in place for a little
over a year.

Good Morning,

We are struggling with Internet bandwidth due mostly to the large
increase in online videos and programming (YouTube, ESPN, Netflix, etc).
We are a small liberal arts school with approximately 1400 students who
live mostly on campus.  We do shape the Internet pipe using a
Packetshaper, but only at an application level (not per person,
connection, or site).  We have been working with a 45 Mbps link since
last March and are trying to figure out what other schools have done to
deal with the increase in demand from residential students and if those
changes are working.

Thank you in advance for your help.
