3. 3 Introduction Discussion Points University Strategic Plan Outside Plant Data Network Services Voice Services Other Infrastructure Issues

4. 4 Introduction: Relationship to University Strategic Plan INITIATIVE FIVE: Ensure an administrative, operational and physical infrastructure that fully supports a first-class university. 2. Create and maintain an electronic networking infrastructure that provides the level of connectivity and data throughput required for our faculty and staff to excel in their research and scholarship and that facilitates innovative approaches to teaching and learning. Continue to upgrade the campus backbone and connections to buildings, aiming in the short term for 100 Mbit/sec to every desktop. Improve access to the campus network from remote and on campus locations and establish widely dispersed on-campus wired or wireless public network access points for the use of those with laptop computers or similar portable devices.

5. 5 Introduction  Replace the campus voice communication system, approaching the end of its useful life, with a state-of-the-art system that incorporates recent technological advances and the convergence of services onto a digital platform that is increasingly provided over data networks.  Develop strong partnerships with national telecommunications companies to aid the deployment and development of cutting-edge telecommunications technologies on campus.

7. 7 Conduit System: Issues Growth Points of Entry Limited access for outside vendors to enter Campus through our duct bank system and continue through campus

8. 8 Conduit System: Areas of Concern

9. 9 Conduit System: Future Construction

10. 10 Cable Plant Copper Cable Category 3 wiring installed in 1990 Category 5 installed in recent construction projects Lifecycle Issues – 20 to 30 year life span Fiber Optic Cable Multi-mode installed in 1990 Not sufficient for newer high speed equipment Distance limited Single-mode Recent installation for core network Need to install to individual buildings New Off-Campus projects are requiring services Coaxial Cable Used for cable television services

13. 13 Data Network Diagram

14. 14 Data Network Growth 17,380 active data connections for 23,669 machines in offices and classrooms 10,119 active data connections for resident students

15. 15 Data Network Service Academic/administrative data network service is switched 10Mb. This is adequate for most applications. However, 100 Mb and 1000 Mb is available for high end networking requirements. Special fiber attached connections are available for network servers. Gigabit Ethernet connections are currently available in the following buildings: Art-Sociology, Computer and Space Science, Engineering Classroom, Lefrak, McKeldin, Physics, Plant Sciences, Tydings Hall and Van Munching. Residence Halls data network service is shared 10Mb. 100Mb to the desktop is becoming standard in office environments. 11.65% of active data connections provide 100 Mb service Most of the campus data network jacks are wired with Category 3 wiring. New construction has Category 5 wiring.

16. 16 Data Network Upgrade Requirements Category 5/6 is required to upgrade data network services above switched 10 Mb. Funding for network service upgrade There are currently 390 equipment locations for 194 buildings More equipment locations are needed since data equipment must be placed within 90m of any twisted pair jack Issues to resolve for equipment locations : Unsuitable environments A/C, electrical, dust, steam and water problems Limited space

17. 17 Example of Unsuitable Equipment Location

20. 20 Wireless Data Network Extension to, not replacement of wired network. Mobility/Flexibility - Provide LAN users with access to real-time information anywhere in their building. Availability - Each wireless access point has a finite range within which a wireless connection can be maintained. Security - Wireless communications can present potential security issues since an intruder does not need physical access to the wired network in order to gain access to data communications. Public Open Network Service and Departmental Service Offerings

21. 21 Wireless Network Access

22. 22 Network Security Incident response, Proactive scanning Campus network security policies VPN Service Firewalls

23. 23 Remote Access Modem Pool 782 College Park lines, 92 Baltimore Lines using v.90 protocol for 56k modems Student access quota is 40 hours in a 14 day period Faculty access quota is 50 hours in a 14 day period Premium modem pool service available to departments for a fee Remote sites Off campus growth requiring campus data service is increasing Data service demands and costs vary Will always be more costly than on campus solutions T1 service meets needs of many projects Leased fiber is an option for larger or high bandwidth locations

24. 24 Internet Service Current connection via Qwest provides 95Mb service Redundant connection to MCI/Worldcom in progress to maintain a high level of service Internet usage doubles every year with associated increasing costs

25. 25 Internet 2 Consortium of over 180 Universities working in partnership with government and industry. Provides high speed connectivity to member institutions for advanced network services. Expands University research capabilities. Internet2 connection provided through relationship with the MidAtlantic Crossroads (MAX)

26. 26 Mid-Atlantic Crossroads Founded by: Georgetown University George Washington University University of Maryland Virginia Polytechnic Institute and State University Max represents a pioneer effort in advanced networking with the potential to incorporate a broad cross-section of constituencies interested in high performance applications and research, including: Higher Education K-12 Federal labs and agencies State and local government Not-for-profit community The Mid-Atlantic Crossroads (MAX) is a multi-state gigaPoP consortium that has deployed an OC48 (2.4 gigabits per second) network. Proximity to Washington, D.C. places it in an advantageous location to partner with: Federal agencies Post-secondary institutions of D.C., Maryland, and Virginia Business community

27. 27 Mid-Atlantic Crossroads

28. 28 Next Generation Internet eXchange (NGIX) NGIXs are “Meet-Me” points for exchange of peering traffic between national and international high-performance networks: UCAID’s Abilene MCI’s vBNS NASA’s Integrated Services Network (NISN) NASA’s Research and Educaton Network (NREN) Defense Research and Engineering Network (DREN) The University of Maryland is Operating the Federal Next Generation Internet Exchange Point for the East Coast. This is a prestigious selection and represents a unique resource and opportunity for the University of Maryland and the participating networks.

40. 40 Conclusion Communications is the key to the delivery of technology throughout the University. Time, distance and location constraints faced today will be overcome by high performance networks supported by a robust infrastructure Need to ensure equity of access to customers with diverse and various levels of technology needs--from simple to complex The University infrastructure is the foundation on which all technologies will run. No single investment will have a greater impact.
