Topics  Tulane campus network  From the inside to the outside  Goldring/Woldenberg Hall to the Internet  Connection to the Internet  Hardware/Connections  Protocols

Goldring/Woldenberg Hall  100-Base-T (100 Mbps) switched Ethernet  Cabletron Systems router (SSR-8)  Cabletron Systems switches (SS-6000, SS-2200)  Cabletron Systems hubs (ELS-100)  10-Base-T (10 Mbps) switched Ethernet  Cabletron Systems hubs (MicroMmac-80)  Other hub manufacturers (Bay, Asante)  Wired to central wiring closets on each floor  Floors connected by copper riser  Fiber riser work budgeted for FY

Goldring/Woldenberg Hall  Connected to campus fiber backbone and the Internet  Cabletron SmartSwitch Router (SSR-8)  100 Mbps, full-duplex  3 subnets managed behind our router  x  x  x  Major protocols  TCP/IP  IPX

Notebook connectivity  Network connections throughout the building provide connection to the Freeman network and the Internet  76 in the Atrium  26 in the Library  40 (total) in Breakout rooms  “Connected” classrooms – 130, 140, 141, 151

The campus connection  G/W Hall  Router to campus fiber backbone  Richardson Building  Campus fiber backbone to router  TCP/IP is the only allowed protocol on the campus fiber backbone 100 Mbps G/W Hall Richardson Bldg RS/6000 Mailhost Admin MVS systems Router to Internet

The campus connection  A buildings is connected to the campus backbone by a router  Card access system communicates over fiber backbone, too  Building/room access  Security gates  Debit card

Campus connectivity (now)  Connection to other campuses and ISP  3-port NMLI  Native Mode LAN Interface  10 Mbps  Uptown, Medical Center, BellSouth  Creates a “bridged domain”  Looks like a big Ethernet segment  Connected to Cisco router

Campus connectivity (now) Uptown Medical Center ISP Internet 10 Mbps

Campus connectivity (future)  Connection to other campuses and ISP  Frame relay over DS3  Full DS3 (45 Mbps published standard)  CIR 15 Mbps  Single connection Uptown  Med Center connected to Uptown by 100 Mbps link  Connected to a Cisco 7507 router

Campus connectivity (future) Uptown Medical Center ISP Internet 100 Mbps 15 Mbps

ISP Connectivity  BellSouth (the world)  Full DS3 out of New Orleans  45 Mbps  Connected to Dallas and Houston  Pipe gets larger as you get closer to the hub

Tulane Dial-up  Managed by TIS  Ascend Max (17)  391 total lines  All lines are PRI  Primary rate interface  Digital back to switch  Support PPP and asynchronous (character-based)  Point-to-Point Protocol

Internet 2  Will be packet over Sonet  Synchronous Optical Network  At STS-3 (155 Mbps)  A published standard Sonet speed  Reserved for research

Thank you!
