2. WatITis | Making the Future | December 2, 2008 | ResNet Enhancements and Directions 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.

3. WatITis | Making the Future | December 2, 2008 | ResNet Enhancements and Directions 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

4. WatITis | Making the Future | December 2, 2008 | ResNet Enhancements and Directions Early Enhancements Wired experience Improvements to bandwidth Housings 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.

5. WatITis | Making the Future | December 2, 2008 | ResNet Enhancements and Directions 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

7. 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 on- site 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 WatITis | Making the Future | December 2, 2008 | ResNet Enhancements and Directions

8. 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 WatITis | Making the Future | December 2, 2008 | ResNet Enhancements and Directions

9. 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 WatITis | Making the Future | December 2, 2008 | ResNet Enhancements and Directions

10. Sandvine Pilot at UW Received trial hardware from Sandvine Trial hardware on site for three months Stage 1 of the pilot started November 21 st, 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

11. 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

12. 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 WatITis | Making the Future | December 2, 2008 | ResNet Enhancements and Directions

13. Pilot Stage 1 WatITis | Making the Future | December 2, 2008 | ResNet Enhancements and Directions

14. 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 WatITis | Making the Future | December 2, 2008 | ResNet Enhancements and Directions

15. Pilot Stage 2 WatITis | Making the Future | December 2, 2008 | ResNet Enhancements and Directions

16. 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 WatITis | Making the Future | December 2, 2008 | ResNet Enhancements and Directions

17. Pilot Stage 3 WatITis | Making the Future | December 2, 2008 | ResNet Enhancements and Directions

18. 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 WatITis | Making the Future | December 2, 2008 | ResNet Enhancements and Directions

19. 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 WatITis | Making the Future | December 2, 2008 | ResNet Enhancements and Directions
