1. Converged Service A Dartmouth Perspective Bob Johnson

2. Background Campus roughly one mile square User population is about 10,000 Over 200 buildings/structures Campus is completely wired Currently 970 APs deployed

3. Convergence Vision Applications are converging –Collaboration & multimedia The economics finally make sense –Focus resources to support one network Must deliver a communications utility –Wireless IP Phones –Speech Activated communications –Streaming Video

4. The Wireless Decision-2001 Dartmouth has a history of investing in technology Computing is pervasive –Mandated for students “Put wireless everywhere and see what happens”

5. First Generation Deployment Cisco Aironet 350 series (802.11b) Over 500 APs installed –Every AP tied to the backbone –Deployed over 18 months Coverage is ubiquitous Approximately 2200 active users per day Traffic types – File sharing, web, email No authentication – “Wireless Frontier” –Standards not set –Could not mandate client

6. Evolving Wireless Vision Must deliver converged services –Same as wired –Support for emerging services Mobility is a given Deliver support for latency sensitive services Wireless Network must act as a “system” with other computing resources

7. Third Generation Wireless Develop two wireless layers –Expand 1 st layer for general purpose bandwidth Low bandwidth access (802.11b  g) to higher bandwidth –Develop 2 nd layer for high bandwidth latency sensitive services (802.11a) (i.e. video, next generation voice) Increase AP density and thus bandwidth –Power control Built-in site survey, auto config –Load balance associations –Reduce or eliminate weak client pulling down others Build for mobility Provide transparent authentication/remediation for access to both wired and wireless network

8. So….What’s been Converged VOIP –Cisco Call Mgr’s supporting hardwired, soft and handheld devices –Vocera Speech Activated communications system Video over IP –Video Furnace encoding 62 channels, Multicast –VOD pilot to support 50 meg, concurrent- Unicast

9. Converged Device Opportunities Handheld converged devices provide opportunity for partnerships within campus –Opportunity to solve problems for other departments –ROI often not directly realized by Computing Services –Projects require not only diverse visionary support, but fiscal as well

11. Mobilizing Dartmouth Where we are going Wired and Wireless security monitoring system 4 Campus wide access for students 1 Wireless VoIP for faculty and staff 2 802.1x security keeps systems secure 6 Real-time people locator for faculty and staff 3 Wireless Video enhances teaching 7 Secure wireless access in lecture halls 5

12. Remote Dartmouth Wireless –Anywhere you have internet access APs “Phone Home” through secure VPN tunnel All remote APs have same credentials –Secure, authenticated access to converged communications resources –VOIP, Video, traditional data –Virtual Office(your campus office in your home) –Traveling Faculty, Staff, Students

13. Automatic Real-time Location Tracking RSSI = X RSSI = Y RSSI = Z The device/user is located  Multi-point triangulation enables fine granularity (within 3 ft)  Real-time location service tracks radio source as it moves  Eliminates manual walkabout to fingerprint RF propagation  Independent of the radio device and drivers

14. Traffic aware I am Matt Green with a laptop using a soft phone Identity aware I am Matt Green, the employee Device aware I am Matt Green with a laptop with no viruses or worms Location aware I am Matt Green with a laptop using a soft phone at 1:40 p.m. in the clinic Policy-based Network Access Service Delivery Based on Who, What, When, Where and How Time aware I am Matt Green with a laptop using a soft phone at 1:40 pm

15. Virtual Attendants Use location dependent services to “push” content to users –Concept of who/where/when –First implementation is campus tour with Vocera Badges Working with Library to provide stack attendant services in un-staffed locations. Other possibilities are campus tours, security/escort services

16. Conclusion While it is the responsibility of Computing Services to provide platforms to provide layered services, the entire enterprise stands to gain from all that convergence to offer. For these convergence efforts to be truly successful, a true partnership needs to develop between CS and the community at large.
