- Fiber can be a maintenance problem (splicing more difficult than for
wire) and a single-point failure.
- Thin net must be supported
- Serial connections must be supported within most work centers
- Appletalk support desirable, especially in the Science Bldg
- Remote work areas with a substantial number of experiments should be
divided into independent local networks (address, physical) to improve
operability, independence from external failures, and portable address
configuration. Recommended areas are Clean Air (and surrounding
experiments), CARA, CMBR (while different), Remote experiments
(Skylab, IRIS), and Station.
- Connect own machine to station within 1 hour of arrival
- Account on station machines within one hour of arrival
- Access methods tcp/ip, Appletalk, serial, [decnet]
- Access to network when satellite visible
- Access to network should not require addition of software to
import machines - address configuration ok
- Open access as feasible
- Support for access to printers, i/o etc.
- Common spares - SCSI disks, printers, monitors, keyboards
- Printer support - Postscript, HP
- Some printers should be supported on network, some by direct connection
- Single point failures have work-around
- Centralized storage - buffering requirements only
- Researchers prefer to use software service with which they are
familiar (editor, mail)
- Home environment preferred for analysis (which implies import
of disks and/or CPUs
- Message preparation
- A substantial amount of keyboard time is spent in message preparation &
- Number of public terminals for this should = 10% of the summer station
- Standard character terminals are adequate for this purpose, should
be able to connect to most station machines (via terminal servers).
Cost per connection = $500.
