All active wired network jacks in the three main Earth Sciences buildings (Mitchell, Green, and Geology Corner) support either 10BaseT (standard ethernet) or 100BaseT (fast ethernet) devices. Some jacks have been upgraded to support 1000BaseT (gigabit) as needed for researchers moving large data sets, upon request to the network manager. All active wired network jacks in the new Yang and Yamazaki Environment and Energy Building (Y2E2) support either 10BaseT, 100BaseT, or 1000BaseT devices. The network switches will autonegotiate to the correct speed.
In the closets, the network switches, with their high speed backplanes, create full-speed connections between pairs of devices. Trunk connections between closets run at speeds of 1 Gigabit/second (1,000 Megabits/second) or higher. Each building has a 1 Gigabit/second connection to the SUNet campus backbone network.
Because our network is fully switched - with each active jack in a room connected to its own switch port - the ability of hackers to spy on network conversations is severely limited. Traffic between pairs of devices goes only to the ports serving those devices and is not broadcast on the rest of the network.
