Finding The Solution
Campus Network
PacketShaper
Firewall
Internet
 25% to 30% of bandwidth to outside
P2P users
 Just a few internal P2P users using the
rest
 Critical applications timed out due to the
bursty traffic

PacketShaper automatically
discovers and classifies hundreds
of different traffic types
Napster, Gnutella,
imesh, Scour, etc.
Precise Classification by:
• Application
• Port
• URL
• Protocol
• IP Address
• MAC Address
• IP Precedence

Analysis Made Easy – Top Ten
 What’s competing for the
bandwidth?
 Top Talkers & Listeners
 Traffic Distribution
Control
 Set policies to control performance
 Per-application
minimum/maximum bandwidth
policies
 Per-user minimum/maximum
bandwidth policies
 Priority-based policies
 More
When Bandwidth is Needed
 Band Together in your Region Oregon Independent Colleges
Association
 Portland Regional Education Network
 Northwest Access Exchange
 Find New Transport Cable Companies
 Power Companies
 Wireless/Optical

Recommendations
 Know what is using your bandwidth
 Identify Mission Critical Applications
 Start the political processes for applying
policies
 Implement a bandwidth management
