Campus Network Advisory Group (CNAG)

• Meets once per month• Membership from IST, Faculties, Library,

Housing• Webpage at http://ist.uwaterloo.ca/CNAG– Meeting minutes– Member reports

• E-mail list cnag@lists.uwaterloo.ca

Wireless• Upgrade to Aruba

– 850 APs on main campus– 535 in Housing residences– Will be installing 802.11n in new buildings

• Coming– Eduroam– Traffic shaping– Network Address Translation (NAT)– Additional APs in high use areas (DC, LIB, SLC)

• Note existing coverage in most lecture rooms designed for light usage only.– Full coverage in lecture rooms average $50 per seat (802.11a/b/g/n AP,

cabling, conduit, etc)

Network Standards

• Discussed at CNAG and CTAG• For campus consistency• Telecommunications Room (TR) standards for

new buildings• Device naming• 1-to-1 patch cabling• POE switches• Routed (layer 3) connections to new buildings

Power over Ethernet (POE) and 1-to-1 patch cabling

• All new buildings, additions, and major renovations use:– POE switches– All jacks live

Application Vendor Approximate Assets

Wired (switches and routers) HP Procurve (90%) $2,000,000

Core and border routers,Server load balancers

Cisco $200,000

Wireless Aruba $800,000

Machine Room Firewall Juniper $100,000

•Multiple vendor•Standards based

Gartner “magic quadrants” for Enterprise LAN, Wireless, Firewalls…

Voice over IP (VoIP)

• Requires Power over Ethernet (POE) switches• Used in all new buildings (e.g. RAC, Pharmacy)• approximately 500 VoIP phones installed to

date• Hoping to offer zero/low cost self serve VoIP

phone moves in areas with all jacks live POE (new buildings)– Requires some development to track locations for

E911.

Network Upgrades• Vendor end of support network gear upgraded

across campus over past 3 years. Central and Faculty funds.

• Academic support buildings upgrading to Power over Ethernet, all jacks live. – approximately $225,000 over 3 years.

Procurve 2610-48-PWR - 48 port 10/100 POE switch $1976.00

Network Service Provisioning

• Project underway to review how wired service is offered.

• Recognition that wireless is self serve and convenient.

• Client request and manual steps required to enable wired service.
