      • Overview
      • Update on Email
      • Update on IM
      • Update on Voice over IP
    • Communicating Today
      • We accept artificial barriers in our communication. Oddly, we think of it as natural.
        • Faxes are sent between two people, each with a fax machine.
        • Telephone calls are made between two people using telephones.
        • Email is sent from one person on a computer to another.
      • We even spend time communicating about communicating
        • Calling each other to arrange to send a fax
        • Sending email to set up a conference call
        • Instant messaging to set up a phone call, etc.
    • Unified Communications
      • Unified Communications is the idea that the dividing lines may fade and even disappear.
      • By bringing together many forms of communication, we can communicate naturally and efficiently
      • Unified communications allows us to
        • Send email to another person’s fax machine
        • Have phone calls using PDAs or laptop computers
        • Move a conversation seamlessly from Instant Messaging to a phone call to a video conference on personal computers or high function handhelds
    • Many communications media Email Phone Vid Conf & Other Fax IM
    • Communications Unified Email Voice Vid Conf & Other Fax IM Presence Communications tools linked to each other, and influenced by “Presence”.

        • AirPennNet-Guest Network Operational July 1, 2008
          • Still designing and planning subnet IP ranges to provide scalability and management
          • NOC will work with LSP’s to set IP ranges for AirPennNet and AirPennNet-Guest Networks
        • Consolidation of all Wireless Networks
          • AirPennNet expansion (SAS and SEAS buildings)
            • SAS work is complete for both AirPennNet and AirPennNet-Guest; AirSAS SSID retirement week of 08/18/2008
            • SEAS has AirPennNet configured but still need to add AirPennNet-Guest (by end of August)
        • Total AP Count in Production: about 1300
        • Recent Wireless Expansion Projects (Vet, NEB & Dental)
          • VET – AirPennNet-Guest has been added to NBC as of 08/04/2008
          • Dental Wireless covers 100% of their complex (space planned for renovations)
          • Nursing at 50% with 90+% intended coverage once renovations are completed within their construction schedule.
    • Wireless Update
      • Short Term Strategy
          • Enhance AirPennNet website to provide more information about the service
            • Coverage maps, FAQ, Technical information
          • Normal/standard operating mode in FY2009
          • Continue with wireless expansion per customer demand
          • Make no major changes or hardware upgrades to the current wireless infrastructure
        • Project to Evaluate Next Generation WLAN
          • Testing new controller-based architecture, 802.11n, and capabilities for real time applications over wireless.
          • RFP drafted and submitted to 3 vendors (Cisco, Meru, Aruba)
          • Review Responses in Early Fall
          • Evaluations ending by end fall.
          • Vendor selection by 01/2009
          • Small Pilot (entire building) by 3Q FY2009
          • Purchase by end FY2009 for FY2010 deployment
        • Design of Campus User Rapid/Self Service to Enable Guest Access
          • Early stages of discussion
          • Targeting end of FY2009 Pilot
    • Next Generation 802.11 Wireless
      • 802.11b – first deployed at Penn in 2000-2001
          • 11 Mb/sec data rate, 2.4 GHz spectrum
      • 802.11a – first deployed at Penn in 2004-2005
          • 54 Mb/sec data rate, alternate radio spectrum
      • 802.11g – first deployed at Penn in 2004-2005
          • 54 Mb/sec data rate, 2.4 GHz spectrum
          • “ backwards compatible” with 802.11b
      • 802.11n to be deployed at Penn in 2009
          • Higher data rates
            • over 100 Mb/sec possible in 2.4 GHz
            • over 300 Mb/sec possible in 5 GHz
          • Much improved multi path handling
    • Wireless Authentication Evolution Timeline Wireless Security 2000 MAC address offline registration. No security measures – didn’t scale, long delays and turn around. 2002 Bluesocket Gateway - https redirect page for authentication. Login secure, but all other data vulnerable, single point of failure. 2005 802.1X AirPennNet authentication using EAP authentication with WEP. 2008 AirPennNet additionally supports WPA Enterprise authentication. Added AirPennNet-Guest for legacy & guest use. Future WPA2 – full 802.11i standard. Full session strong encryption. Greatly reduced vulnerability to a range of attacks (authentication , foraging, replay, key collision, weak keys, packet foraging, brute-force/dictionary attacks)
    • New Wireless Architectures
      • Possible controller based solution:
        • Streamline management – installations, configurations, radio & power management
        • Cell based architectures may help with client roaming decisions (less dropped connections)
        • Secure fast roaming (roaming from one AP to another is handled per building and not autonomously)
        • May also help with real time application performance
    • Proposed Wireless Guest IP Funding Model
      • Goal : To enable proper IP ranges for AirPennNet and AirPennNet-Guest, and to ensure use of AirPennNet as primary wireless network
      • Key Concepts:
        • AirPennNet is strongly recommended as primary wireless network for Penn faculty, staff, and students (security, speed, and availability)
        • AirPennNet-Guest was designed for visitors and for devices incapable of supporting 802.1x. (network has restrictions and is less secure)
      • Policy: Previous Wireless-PennNet policies allowed for some centrally subsidized IP addresses for public areas. AirPennNet-Guest allows for visitors to roam to all areas of campus. Two ranges of IP addresses for AirPennNet & AirPennNet-Guest make it difficult to manage the IP ranges (i.e. costs) to a minimum.
      • Propose that 10% of IP range for AirPennNet networks be subsidized for IP range in AirPennNet-Guest networks. Schools or centers will pay for IP costs greater than 10% of AirPennNet IP range.
    • Proposed Wireless Guest IP Funding Model
      • Cost impact to CSF FY’09
        • 4041 IP’s assigned for Wireless-PennNet in FY’08.
        • 10% cost of those IP’s equals 404 * $4.29  * 12 = $20,798 per year.
        • Costs would be absorbed by ISC in FY’09
      • Potential cost impact to CSF FY’10
        • 8000 IP’s assigned for AirPennNet projected
        • 10% cost of those IP’s equals 800 * $1.67  * 12 = $16,032 per year.
        • This cost could be added to the CSF for FY’10.
