7. VOIP Background and Drivers
Significant amount of campus construction and renovation providing green field opportunities.
Multiyear open source never got out of lab
Successful pilot with Cisco UCM 6.x
Timing of West Campus driving us to make decision to invest more in TDM or migrate to production VOIP

8. VOIP Decision to move forward with CUCM with existing Nupoint VM
1st large scale production use in renovated 700 person ITS/Finance and Administration building go-live 10/08
~5000 potential voip sets identified over next 5 years

9. VOIP VOIP at Yale is at least two Projects Technology:
How big is the IP-PBX ie. servers?
How fast does the network need to be?
How do we integrate it with existing systems?
How do we make it highly availably?
Business Process
How do we install this new service?
How do we move this services?
How do we trouble shoot problems?
How do we bill for our services?

10. VOIP Interesting Challenges:
The phones must remain active for xx minutes during a power failure.
Power for phones now comes from network closet rather than central telephone switch room. How can I provide emergency power in every network closet?
The quality of the phone call can not be affected by other network conditions
Voice and Data are now running on one converged network. How can I ensure the voice traffic is given the appropriate priority level on the network?

11. VOIP Interesting Challenges:
Every physical phone has a unique identifier that is administratively tied to a phone number/person. Traditional phones are administratively tied to a cable pair/location.
Current phone add process
Need to define and optimize new process

12. VOIP Interesting Challenges:
Required by law to provide phone location for purpose of emergency calls. E911 services are currently managed by manually maintaining a database that maps phone numbers to locations.
Current process requires a technician to move phone and also allows for E911 database maintenance.
Need to define and optimize new process or technical solution.

13. VOIP Rethinking the Edge Currently using HP Procurve at edge
10gb to the closet
High density POE
Traffic Management
Edge Security: Positioned for NAC
Switch and Device communications (ie. CDP)
Fine power management

14. Backbone Network Upgrade
Today’s Backbone
Composed of Cisco 65xx series Catalyst Switches running at Layer 2.
Older switches with only 64mbps backplane
1 Gbps connections to campus routers and internet gateways.
Design provides only manual failover for link failures
Firewalls are externally connected with maximum total throughput of 330Mbps-1.7Gbps

15. Backbone Network Upgrade
Future Backbone
Meeting with stakeholders to define requirements and Investigating Alternatives
General themes in requirements
Faster: More Bandwidth
Higher Availability
Integrated Security
Evaluating HP and Cisco designs

16. Backbone Network Upgrade
Future Backbone
Sample Potential Design
Cisco 65xx series Catalyst Switches running at Layer 3.
10Gbps connections to campus routers and internet gateways.
Design provides only automatic failover for link failures
Firewalls are could be imbedded with maximum total throughput of at least 5Gbps
