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.


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 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.


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

ResNet

Non-ResNet

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


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


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

PTS 8210Policy Traffic

Switch


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

SRP 3000 reporting platform


Pilot Stage 1


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


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


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
