  1. Resnet Enhancements and Directions Part 2, Bill Baer, Housing & Residences - Information Systems

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

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

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

  6. Monthly AverageExternal Bandwidth (Mbps) WatITis | Making the Future | December 2, 2008 | ResNet Enhancements and Directions

  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 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

  11. PTS 8210Policy Traffic Switch PTS 8210Traffic 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 WatITis | Making the Future | December 2, 2008 | ResNet Enhancements and Directions

  12. SRP 3000 reporting platform SRP 3000Reporting 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 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

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

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

  22. VoIP Calls by Provider WatITis | Making the Future | December 2, 2008 | ResNet Enhancements and Directions

  23. Average Call Duration WatITis | Making the Future | December 2, 2008 | ResNet Enhancements and Directions

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