  1. FS/ILG House Managers IAP 2005 Oliver Thomas Information Services & Technology

  2. Agenda • Networking (Data) • General network architecture • Problem reporting and escalation chain • Useful e-mail addresses and contacts • Upcoming bandwidth upgrades • Demise of Service Level Agreements • Telephones

  3. General Network Architecture • On-campus ILG’s and ILG’s on Mass Ave have (MIT) fiber to the building • Off-campus ILG’s currently have Verizon T1’s from one of MIT’s routers to the ILG • Bandwidth is 1.54 M-bits/sec • Planned upgrades • Line conditioner, router

  4. Cisco Router (2000 series)

  5. MITnet Map (Overview)

  6. MITnet Map (Detail)

  7. Network Internal to House

  8. Hubs, Switches and Routers • Each ILG has a large address space (don’t use back-end networks) • Home routers generally don’t work well in this context (look for “bridging mode” in documentation) • Want access points, switches, or hubs to extend networks

  9. General Service Model • MIT maintains the entry equipment • Verizon maintains the T1’s • ILG’s maintain everything inside the entry router • Most MITnet services are available inside ILG subnets • DHCP registration service • Moira host database • Security scans and notifications

  10. Problem Reporting and Escalation Chain • Tiered model • Tier 1: ILG Network Contacts • Tier 2: ILG Coordinators(ilg-net-help@mit.edu) • Tier 3: MIT Network Operations / Verizon • Generally problem reporting should start with the ILG Network Contacts • If ILG Net Contacts cannot be reached HM’s should use ilg-net-help list directly (please make sure to identify yourself and say that you tried to reach the Net Contact)

  11. Net Contact Responsibilities • Help residents connect to MITnet • Create proper hostname entries and keep them current • Cooperate with IS&T staff to resolve problems • Adhere to MITnet rules of use and the rules in the Quick Guide • Keep ilg-net-help@mit.edu updated with changes to network contacts

  12. Outages • Equipment beyond the MIT router is the responsibility of the ILG • Attempt to debug the problem • Ping other hosts on your subnet • Ping your router • Ping some other host on MITnet that isn’t on your subnet • Connect one machine to the networking equipment and see if that machine can reach your router and other hosts on MITnet • If the problem isn’t internal, follow the contact instructions in the QuickGuide

  13. DHCP Registration • Active in all FSILG’s • Set “obtain IP address automatically” • Set “obtain DNS servers automatically” • Browse to any web address

  14. Maintaining Connectivity • Highly cooperative effort between MIT, Verizon, and ILG • Because of the number of players involved we occasionally run into “passing the buck” problems • Open and reliable communication is critical • Important to keep Net Contacts up to date

  15. Useful Contact Information • Your ILG Network Contacts • Designate one primary Network Contact • https://web.mit.edu/rescomp/ILG/ilg-contacts.txt • Keep address records current • ilg-net-help@mit.edu list • Adam D’Amico • Angie Kelic • Oliver Thomas

  16. Upcoming Bandwidth Upgrades (Spring 2005)

  17. Demise of Service-Level Agreements Transition to a more cooperative and less segregated approach (Risks and opportunities)

  18. Telephones

  19. Discussion and Q&A Contact info: Oliver Thomas othomas@mit.edu
