    Unified Communications Update bringing many modes of communications together 4

    Slide 5:Agenda

    Overview Update on Email Update on IM Update on Voice over IP 5

    Slide 6: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. 6

    Slide 7: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 persons 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 7

    Slide 8:Many communications media

    Slide 16:Update on Voice over IP

    VoIP overview Verizon HIPC evaluation Current PennNet Phone Deployments Recent developments with PennNet Phone Future PennNet Phone development plans 16

    Slide 17:VoIP Overview

    VoIP in worldwide communications Major player in Long Distance / IXC service Retail services like Vonage SIP trunking services to enterprises Enterprise VoIP options Cisco Call Manager Avaya and other vendor solutions IP Centrex (such as Verizon HIPC) Open source VoIP 17

    Slide 18:Verizon Hosted IP Centrex

    Hosted (not managed) service in Verizon Network Uses feature-rich Broadworks software Local phone provisioning and configuration management handled by enterprise Back-end handled by Verizon Verizon has only small deployments to date Penn had a very mixed experience in a 90 day trial Many good features Others did not work as advertised or at all Long delays to get phones into service Some unexplained outages Not a full outsourced solution. Penn would still have significant costs and responsibilities Over a year of joint development necessary before we could roll it out widely on campus. Decision made to stay with PennNet Phone only for now. 18

    Slide 19:PennNet Phone Today

    Production-grade, enterprise VoIP Services Redundant servers, gateways and PRIs 24x365 monitoring and management Single-line features, email/voicemail integration 911 support equal to traditional system Location information able to be updated via web Roughly 1,500 VoIP phones in full production More than 80 LSPs involved today 19

    Slide 22:Recent Fixes and Coming Feature Releases

    Recently fixed a long-standing Consultative Call Transfer problem Currently in test/pilot Call Hunting Forward on ring-no-answer Forward on busy Planned Feature Release Bridged Line Appearance with Busy Indicator Find me/Follow me Set Ring Delay before voicemail Direct transfer to voice mailbox 22

    Slide 23:Voicemail

    PennNet Phone uses the popular voicemail service from Digium Asterisk is an open source project. Penn has contributed code to the project to implement many features important to our users A very basic version is in use today with PennNet Phone (about 1500 users) A more feature rich version is available to pilot users (about 150 users) An advanced version is in internal testing, with a very large set of Octel features. Full unified messaging has been developed. When you listen to your new voicemail through your e-mail client, your message waiting indicator will turn off! 23

    Slide 24:Telephony at Penn Going Forward

    Centrex remains the primary telephony service to thousands of campus customers today PennNet Phone is the direction forward for flexibility, application integration and ultimately for cost management The transition will take place over several years 24

    Slide 31:Wireless Update

    Current Status Wireless-PennNet Retirement on 06/30. Saved $180k/year. AirPennNet-Guest Network Operational July 1, 2008 Still designing and planning subnet IP ranges to provide scalability and management NOC will work with LSPs 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. 31

    Slide 32: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 32

    Slide 33: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 33

    Slide 34:Wireless Authentication Evolution

    34

    Slide 35: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 35

    Slide 36: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. 36

    Slide 37:Proposed Wireless Guest IP Funding Model

    Cost impact to CSF FY09 4041 IPs assigned for Wireless-PennNet in FY08. 10% cost of those IPs equals 404 * $4.29 * 12 = $20,798 per year. Costs would be absorbed by ISC in FY09 Potential cost impact to CSF FY10 8000 IPs assigned for AirPennNet projected 10% cost of those IPs equals 800 * $1.67 * 12 = $16,032 per year. This cost could be added to the CSF for FY10. 37
