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.

Newark Campus
Camden Campus
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).
