                      NETWORK HOST STATUS

This RFC reports on the status of most Network Hosts from July 3 to July 14.

No testing was done on July 4 as BBN took a holiday to celebrate Independence Day. No testing was done on July 11 and 12 as I was on vacation.

Several Hosts are currently excluded from the daily testing as they are presently intended to be users only. Included here are the Terminal IMPs, which are presently in the Network (AMES, MITRE, RADC, NBS, ETAC, USC, GWC, NOAA, SAAC, ARPA, and BBN*). This category also includes the Network Control Center computer (Network address 5) which is used solely for gathering statistics from the Network. Finally, included among these Hosts are the following:

Network Address Site Computer

The tables on the next two pages summarize the Host status for this period.





  • The BBN Terminal IMP (Network Address 158) is a prototype and as such

is frequently not connected to the Network, but being used to refine and debug the Terminal IMP programs.

where

D = Dead (Destination Host either dead or inaccessible [due to network
 partitioning or local IMP failure] from the BBN Terminal IMP.)
F = Full (Destination Host opened a connection, informed user that all
 Network ports were in use, and immediately closed the connection.)
H = 1/2 Open (Destination Host opened a connection but then either
 immediately closed it, or did not respond any further.)
O = Open (Destination Host opened a connection and was accessible to
 users.)
R = Refused (Destination Host returned a CLS to the initial RFC.)
T = Timed out (Destination Host did not complete the ICP and open a
 connection within 60 seconds.)

  • The only service currently offered by the UCLA IBM-360/91 is a Network

Job Service (NETRJS), however, the BBN Terminal IMP is not equipped to test NETRJS. We are assuming that initial connection to the NETRJS logger indicates that NETRJS is also functioning.

  1. These sites advertise that they may not have their system available at

these times.

with each user.
