Internet Bandwidth Shaping
In order to help ensure that the University's Internet connection continues to effectively
meet instructional needs and the University's academic mission, the University uses
bandwidth shaping (aka" traffic shaping") to manage its Internet data traffic. Bandwidth
shaping assigns priorities to data traveling to and from the Internet. Bandwidth shaping
helps us better manage our Internet connection, and provide more reliable Internet
services to our campus community.
What it is
The device the University uses to shape Interent traffic is a single purpose hardware
and software solution. Our "bandwidth shaper" is located between the campus network
and our campus firewall.
What it does
The bandwidth shaper does two things: network monitoring and bandwidth shaping. We
can monitor our campus Internet connection for types of traffic using our network
bandwidth. We can also see the computers using the most bandwidth. Traffic shaping
lets us set rules for how we want to use our Internet connection. For example, we
can say that web traffic from instructional areas get the highest priority on our
What it doesn't do
The bandwidth shaper does not affect data traffic within our campus network. Data
traffic to and from Illinois Wesleyan computers on campus for the registration system,
network neighborhood and other campus resources are not affected by traffic shaping.
We only prioritize traffic going to and from the Internet.
How it prioritizes Illinois Wesleyan Internet traffic
We can shape Internet bandwidth by virtual channels and by individual connections.
We organize by the type of Internet application being run. Our intent is to place
instructional needs first. Web traffic gets highest priority. Peer-to-peer traffic
is limited, and prioritized based on bandwidth available.
