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 ILGBandwidth is 1.54 M-bits/secPlanned upgradesLine conditioner, router

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

Problem Reporting and Escalation Chain
Problem Reporting and Escalation Chain
Tiered modelTier 1: ILG Network ContactsTier 2: ILG Coordinators
([email protected])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)

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

Maintaining ConnectivityMaintaining 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
