Who Is Pacific? 2100 full time undergraduate and graduate level students, 600 faculty and staff Campus locations in Forest Grove, Portland, and Eugene Oregon 14 IT staff members
Just Give Them Bandwidth
Finding The Solution 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 Campus NetworkPacketShaperFirewallInternet
Getting It Under Control Before After
Getting It Under Control With Control Without Control
Packeteer’s 4-Step Process
Layer 7 Classification Physical Network Data Link Transport Session Presentation Application PacketShaper Routers Switches Firewalls 1 7 6 5 4 3 2 PacketShaper automatically discovers and classifies hundreds of different traffic types Precise Classification by: Application Port URL Protocol IP Address MAC Address IP Precedence Napster, Gnutella, imesh, Scour, etc.
The New Fall Line Napster’s Replacements
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
P2P Ratios Plugs to the Pillow 1/1 Pipes to People 1/4 Policy to Pain 1/1
Recommendations Know what is using your bandwidth Identify Mission Critical Applications Start the political processes for applying policies Implement a bandwidth management solution like the PacketShaper Add bandwidth only when needed to support policies
