  1. Networking and Telecommunications 17. RUNet-Rutgers Network

  2. Wan • 3 cities, t1 and t3 lines, oc3 • Multiple (3) connections to internet (2 to the commodity internet via Sprint -155 mbps, Verizon -35mbps, and 1 to I2 via Abilene - 155 Mbps (Internet II) -redundancy • Buildings on each campus wired via campus backbone (fiber) cable, routers and switches. Normally one router per building.

  3. Newark Campus CamdenCampus New Brunswick Campus Internet

  4. Lan • Offices and labs, primarily ethernet, twisted pair, star topology • Some older technologies exists or did in the past, including arcnet, token ring, thick and thin coax ethernet, bus topologies, etc.. • Buildings contain backbone cable (fiber or coax) to connect every floor's wiring closet. A hub and/or switch in each wiring closet, to network each lab/office in a star configuration. • Moving away from hubs, towards switches only (10/100 switches) • Campus backbone is based on fiber, switches and 1 gigabit ethernet

  5. tcp/ip, appletalk, ipx/spx • Main protocol is tcp/ip • Moving towards tcp/ip only • Novell, unix, nt, macs - client/server approach (no mainframes on Camden campus). ibm mainframe in central campus in N.B.

  6. Modem pools and access/terminal servers. 72 modems running v.90 (56k) in Camden. Moving towards reducing modem pool (many users have moved to DSL/Cable modems)

  7. RUNet 2000 • 5 year project, 100 million+. 600 building and backbone wiring/re-wiring. 3 cities, many campuses. Upgrade fiber wiring, routers, and switches as part of backbone. Upgrades between building and backbones within buildings. • Ethernet based (10/100/1000), tcp/ip only. Enhanced cat 5e TP wire. • Carry data, voice, and cable/video. Joint project with Bell Atlantic (Verizon). • Includes OC3 link (155Mbps) from Camden to N.B./Internet.

  8. 2 class B ip addresses • 128.6.xxx.xxx • 165.230.xxx.xxx • Use subnets (typically 3rd field in address) • Heavy Use of Switches and Vlans • Increasing the use of firewalls and private ip address space • VPN connections available

  9. Internet II • Non commercial traffic, research only. • Universities and major research labs. • Rutgers has OC3 pipe to I2 directly (155Mbps).
