Resnet Enhancements and Directions
Part 2, Bill Baer, Housing & Residences - Information Systems
Overview
 The challenge - delivering Internet access to 5,000
clients ... and keeping in mind it is their “home”.
 ResNet Daily Fuel Tank Quota increases.
 500MB/day ---> 1GB/day ---> 2GB/day
 Introduction of Wireless Infrastructure.
 Pros and cons of introduction
 Bandwidth Traffic Optimization.
 Replacing aged ACL & “Bad Boys” List
 Future directions and projects.

The Goals & Challenges
 Overall goals of the ResNet Infrastructure.





Understand our clients needs, expectations and deliver!
Introduce a feedback-loop to improve services
Provide Internet experience similar to or better then home
Enhance clients Internet experience with Wi-Fi
Ensure all VoIP options are available to our clients
 Challenges (yet to be achieved)
 Track client usage across Wired & Wireless infrastructures
 Provide equal quota on Wired & Wireless infrastructures
 Develop an alternative for “top talkers”

Early Enhancements
Wired experience
 Improvements to bandwidth




Housing’s 40% contribution & 200Mbps - 400Mbps access
August 2008 doubled to 1GB/day per client
Increased “Bad Boy” bandwidth portion to 10Mbps
October 2008 doubled again to 2GB/day per client
 First survey released, with prizes to stimulate
results. Early results of 650 (13%) respondents





98% are satisfied with connection speed
82% are satisfied with current limits
Only 1.5% have alternate Internet provider
52% watch TV (CDN & Alt. broadcasters) via WebTV
10% have Rogers Cable TV connected to their room.

Early Enhancements
Wireless experience
 As earlier indicated installed nearly 500 APs, in less
then 3 months, with co-op student wiring crew.
 Nearly 60% were AP-70s to eliminate conduit; introduced
two MAC address per port; 10% of those clients
experienced connectivity issues, due to PC configurations
 Early survey results
 84% satisfied with wireless connectivity
 77% use both wireless and wired infrastructures; thus
effectively much more then 5000 clients
 Survey results will be used to fill ‘holes’ in Wi-Fi;
200+ APs ready to be deployed

Why Introduce Bandwidth
Traffic Optimization?
 Some of the reasons to change…
 Previous slide indicates significant growth in usage
 Main router (RN-RT-MC) for ResNet getting older; no onsite spare and have discontinued Cisco support
 CPU load approaching 70% and continues to growth
 Current fuel tank shaper no longer supported by IST
 Fuel tank shaper not very graceful
 Does not allow for different levels of service or protocols
 “Bad Boys” List bandwidth is STATIC

Investigation of New Traffic
Management
 Research started in Fall 2008
 Already in use in many universities, mostly
Packeteer (recently acquired by Blue Coat)
 Most shapers deployed in universities/colleges
target specific protocols (i.e. Peer-to-Peer)
 Many different vendors

Sandvine Networks
 Company headquartered in Waterloo at 408 Albert
Street (300+ employees worldwide)
 Primarily deployed in large carrier networks in the
United States & Canada (i.e. Rogers)
 Manufacturing/Support takes place in Waterloo
 UW is the FIRST educational institution to use
Sandvine equipment, others interested in pilot
 Sandvine traffic shaper programming similar to UW
developed NAA (Toilet Tank) traffic shaper

Sandvine Pilot at UW




Received trial hardware from Sandvine
Trial hardware on site for three months
Stage 1 of the pilot started November 21st, 2008
3 stage pilot
 Stage 1 – Port mirror of Village 1
 Stage 2 – Village 1 installation (starts tomorrow)
 Stage 3 – Remainder of residences added
 Pilot Hardware consists of two devices
 PTS 8210 & SRP 3000
WatITis | Making the Future | December 2, 2008 | ResNet Enhancements and Directions
PTS 8210
Traffic Management Switch
 1U appliances
 Core of unit is BSD Unix
 Sits “in-line” and monitors all inbound and
outbound traffic
 Performs Deep Packet Inspection on all traffic
 Capable of performing 1 GB/Sec of DPI
 Services such as Don VoIP Phones and switch
management exempted from inspection
PTS 8210
Policy Traffic Switch
WatITis | Making the Future | December 2, 2008 | ResNet Enhancements and Directions
SRP 3000
Reporting Platform
 3U Server
 Configured with 2TB or 4TB of disk space
 Collects statistics from PTS 8210 about subscriber
behaviour
 Allows for identification of all protocols being used
on the network
 Web based administration allows for reports to be
created “ad hoc” or run on a schedule
SRP 3000
reporting platform

Pilot Stage 1
WatITis | Making the Future | December 2, 2008 | ResNet Enhancements and Directions
Stage 1 Details
PTS is configured in “off-line” mode
Traffic from Village 1 is analyzed but not shaped
Allows for “what if” scenarios
Data is collected to give network team a view of
what is happening on the network
 Ensure devices do not fail

Pilot Stage 2
WatITis | Making the Future | December 2, 2008 | ResNet Enhancements and Directions
Stage 2 Details
 1 subnet of Village 1 wired traffic is shaped initially
 If PTS performs as expected all of Village 1 wired
traffic will be shaped

Pilot Stage 3
WatITis | Making the Future | December 2, 2008 | ResNet Enhancements and Directions
Stage 3 Details
 Slowly start moving of rest of residence complexes
 Plan is to have stage 3 up and running before end
of exams to “stress test” equipment

Network Demographics
 The SRP reporting platform allows for network
administrators to determine what is happening on
the network
 Large amount of reports to run, could be a full
time job for someone just to analyze data
 All data in the following slides is from Village 1

Future Directions and Projects
 Investigate options to provide “ultimate”
bandwidth packages for ResNet clients, for the
18% not satisfied with current standards
 Wi-Fi access for gaming consoles
 Aruba Networks License testing
 Voice Services, Remote AP & Wireless Intrusion Protection
 SwitchVox (VoIP) Pilot for Winter 2009
 HP Procurve Manager Pilot for Winter 2009
 NAP (health check) is currently under investigation
