  1. Mobility and the Future of Integrated Communication Strategies Mike Staman – Macon State Jim Jokl – University of Virginia EDUCAUSE 2003

  2. What are Integrated Communication Services (ICS)? • Many definitions over the years • Financial perspective • Lets run our telephone system over the data network • Voice over IP (VoIP) • Can’t we also run video over the data network? • H.323, MPEG, Real Networks, Quicktime, etc • Services perspective • Can we link our voice mail and email? • Unified Messaging products • Can videoconferencing enhance productivity / avoid travel? • What are the new “killer applications”?

  3. What are Integrated Communication Services (ICS)? • Technology perspective • What services should we deploy for our users? • How do I keep my school from falling behind? • “They” are doing wireless, so we should be too • Should we deploy Skinny or SIP or H.323 for VoIP? • What are the implications for the campus network? • Basic question • How do we keep up with growing user expectations? • Especially hard in the current fiscal environment

  4. User Expectation Trends • Access many services from one workstation • Access the same services from many devices • Location independence • Wired office network connection • At a wired network café • On the wireless LAN • In a home office • Out of town

  5. A refined vision for ICS: Support for Nomadic Computing • Access to voice, data, and video communications applications via device, location, transport, and media independent mechanisms • Implies services such as locating a person via one of many devices, at any location, originating ID portability, integrated or find-me messaging, authentication and privacy, etc

  6. Today’s Agenda • We’ll discuss some of the implications of meeting these user expectations • Technical issues • Financial model changes • Policy and organizational aspects • Service examples and planned projects

  7. Technical Implicationsfor the wired campus network • A stable cable plant and database • 10/100 switched Ethernet • A high-capacity network backbone • Provisions for end-to-end management • QoS support • Multicast support • A wiring closet UPS infrastructure • Backup power is for more than just E-911

  8. Technical Implications for the wireless campus network • Existing applications use 802.11b • Insufficient even for the near term • Performance inadequate – 11 Mbps best case • Shared network • Security issues • Poor access control • Lack of available channels (spectrum) • 802.11G helps - compatible with 802.11b • Up to 54 Mbps • Still a shared network in same 2.4 GHz band

  9. Technical Implications for the wireless campus network • Fortunately wireless equipment also takes advantage of Moore’s Law • 802.11n • 100+ Mbps in the 2005/06 time frame • Wireless PANs • Bluetooth: 30 feet, 64 kbps to 1 Mbps • 802.15.3: up to 55 Mbps, multimedia capable • Coexist with 802.11b/g in 2.4 GHz band

  10. Technical Implications for the wireless campus network • Wireless VLANs & QoS • Traffic isolation, support for voice applications • What about 802.11a • Many channels – operates in 5.8 GHz band • Cost coming down; support for b/a/g cards • Vivato-type technology • Phased-array antenna directs radio energy where it is needed

  11. Technical Implicationsfor remote network access • How do we enable the nomadic concept for off-campus students and faculty? • Is this really just plain old telecommuting? • Many campuses have been successful implementing network peering relationships with ISPs • Lease copper and install private DSL? • Leverage next generation of wireless technology?

  12. Technical Implicationsfor Wireless Metro Area Networks • 802.16a WiMAX • The next big thing in wireless space? • Licensed and unlicensed operation • Unlicensed in the 5.2 GHz and 5.8 GHz bands • Near line of sight • Up to 30 miles and 70 Mbps • Will perform well with wide range of packet sizes • Large investments by Intel, others • Mid-2004 for products

  13. Technical Implications for Cellular Device Integration • User’s desire • Voicemail, paging, and messaging integration • Desk phone calls to reach their mobile device • “Wireless Office” functionality • Feature transparency & integration • No per-minute charges for on-campus use • Wide area coverage • Personal use enabled • Two numbers, call tagging, etc?

  14. Technical Implications for Cellular Device Integration • Integration with campus WLAN • Some new cell phones support 802.11b VoIP • Relationships with carriers essential • Colorado State, Virginia, others working on procurements in this area • Integration with campus LAN • Bluetooth phones for remote data network access

  15. An Interesting Wireless Integrated Solution: Vocera • 802.11b WLAN badge • Voice recognition activated • Integrated services • Voice over WLAN • 2-way telephony integration • Voicemail • Audio email • Text messaging • Group broadcast • User location feature

  16. Wireless Impediment: Security • Security problems can devastate a campus wireless LAN • Wireless has low capacity and is a shared media • Wireless QoS is in its infancy • You often can’t shut down an offending computer • Rogue access points • Ad-hoc mode • Poor vendor security architectures • Need a security model that spans network transport

  17. Wireless Access Control and Data Privacy • Common mechanisms • VPN, LEAP, EAP-TLS, PEAP, etc • Vernier, Bluesocket, etc • Remember limitations of special devices • PDAs, cell phones, VoIP phones, Vocera badges • Design infrastructure to support many mechanisms

  18. Will we do a lot of planning only to be overtaken by events? • In which multimedia transport should you invest? • Cisco’s skinny VoIP protocol • H.323 • Wait for SIP to be deployable on a large scale? • What about Skype?

  19. Skype • A peer-to-peer system for Internet telephony • From the people who developed KaZaA • Designed to work in the presence of firewalls, NAT, PAT • All traffic is encrypted and better voice quality • Technical implications • Network infrastructure needs are similar • but P2P applications are harder to support

  20. Some Financial, Organizational and Policy Implications to Consider • A fundamental change in user relationships? • We already consider the whole student experience • Can we strengthen it further with new technology? • Retain their interest better after graduation? • Is the technology about to make this possible for faculty and staff? • How are you organized? • Voice, data, video integrated? • Cell phones in purchasing? • Support as network complexity continues to grow

  21. Some Financial, Organizational and Policy Implications to Consider • Do you recover costs for the right services? • Typical schools charge for items such as • Telephone • Network jack • Backbone • Internet capacity • Monthly cell phone and airtime minutes • Wireless LAN service • Remote access • Cable television

  22. Some Financial, Organizational and Policy Implications to Consider • Do voice recoveries help pay for LAN or wireless • What about Skype or Windows messenger? • Current cost recovery practices are often a disincentive for Nomadic Computing • We want users to have their phone number everywhere • Wireless devices, cell phones, desk phones, soft phones, telecommuting, etc • Enabling personal use should be a goal • Money can be saved by both the school and the individual

  23. Some Financial, Organizational and Policy Implications to Consider • An alternate financial model: might per-person cost recovery work? • Fund a basket of basic infrastructure services • Automatically scales like per-device charges • No disincentives for multi-device nomadic users • Use financial motivators to limit excess consumption • One-time charges for expensive phones, software licenses, items such as Vocera badges, etc? • Normal billing for excess needs such as large numbers of network jacks, high Internet capacity, etc?

  24. Some Financial, Organizational and Policy Implications to Consider • Many possible financial alternatives • Focus on overhead-type funding? • Per-user instead of per-device charges? • Continue with per-device charges? • Ensure that charges reflect the true cost of a service • Avoids providing a financial incentive for users to do the wrong thing over the long run

  25. Coming Events • What is next for the ICS Group • ECAR Project • Research report on Integrated Communications in Higher Education • Future Meetings • Changes in standard meeting schedules

  26. Is your campus working in these areas or is it an interest of yours? • Consider joining the ICS working group • http://www.educause.edu/netatedu/groups/ics • Next meeting – Tempe AZ - February • Topic
